A slide assist device includes a draw-in unit including a case attached to one of a main body or a mobile body, a slider slidably placed on the case, a latch pivotally supported in the slider and switchable between a standby position locking in a corresponding portion of the case and a draw-in position releasing the locking; and an urging device; and an actuating member attached to the other of the main body or the mobile body, switching the latch from the standby position to the draw-in position, or from the draw-in position to the standby position. The latch includes an axis portion having a flat surface and rotatably fits in an axis hole of the slider and forming a positional control surface corresponding to the flat surface. When the latch is switched to the standby position, the flat surface and the positional control surface face each other.

1. A slide assist device, comprising: a draw-in unit including: a case adapted to attach to one of a main body or a mobile body,a slider slidably placed on the case,a latch pivotally supported in the slider and capable of switching between a standby position in which the latch is locked in a corresponding portion of the case and a draw-in position in which the latch is released from the case, andan urging device connected to the slider and arranged to accumulate an urging force thereof, andan actuating member adapted to attach to the other of the main body or the mobile body, and arranged to be able to engage with the latch so that the latch is switched from the standby position to the draw-in position, or to be able to disengage from the latch so that the latch is switched from the draw-in position to the standby position,wherein when the latch is switched from the standby position to the draw-in position, the urging force accumulated in the urging device moves the mobile body from a first position on a main body side to a second position through the actuating member,wherein the latch includes an axis portion having a D-shape including a circular portion and a flat surface along an axis direction, and the slider includes an axis hole to rotatably fit the axis portion, and the axis hole having a D-shape including a circular portion corresponding to the circular portion of the axis portion and a positional control surface corresponding to the flat surface, andthe draw-in unit is arranged so that when the latch is switched to the standby position, the flat surface of the axis portion and the positional control surface of the axis hole face each other, and when the latch is switched to the draw-in position, the flat surface of the axis portion abuts the positional control surface of the axis hole and prevents the axis portion from further rotation. 2. A slide assist device, comprising: a draw-in unit including: a case adapted to attach to one of a main body or a mobile body,a slider slidably placed on the case,a latch pivotally supported in the slider and capable of switching between a standby position in which the latch is locked in a corresponding portion of the case and a draw-in position in which the latch is released from the case,a resistance-imparting portion provided on a sliding-and-contacting surface of the slider or the latch in which the sliding-contacting surface is a surface between the latch and the slider, and acting as a resistance or a friction force when the latch is turned as a supporting point of a pivot portion relative to the slider, andan urging device connected to the slider and arranged to accumulate an urging force thereof; andan actuating member adapted to attach to the other of the main body or the mobile body, and arranged to be able to engage with the latch so that the latch is switched from the standby position to the draw-in position, or to be able to disengage from the latch so that the latch is switched from the draw-in position to the standby position,wherein when the latch is switched from the standby position to the draw-in position, the urging force accumulated in the urging device moves the mobile body from a first position on a main body side to a second position through the actuating member, andthe resistance-imparting portion has a concave-convex shape in which a convex portion of the resistance-imparting portion is positioned in the middle of a rotating direction of the pivot portion, and in which a concave portion is disposed on the opposite side of the convex portion. 3. A slide assist device, comprising: a draw-in unit including: a case adapted to attach to one of a main body or a mobile body,a slider slidably placed on the case,a latch pivotally supported in the slider and capable of switching between a standby position in which the latch is locked in a corresponding portion of the case and a draw-in position in which the latch is released from the case, andan urging device connected to the slider and arranged to accumulate an urging force thereof,an actuating member adapted to attach to the other of the main body or the mobile body, and arranged to be able to engage with the latch so that the latch is switched from the standby position to the draw-in position, or to be able to disengage from the latch so that the latch is switched from the draw-in position to the standby position,a piston braking device comprising a structural member, for damping a moving speed by an urging force of the mobile body,a fixing ring as a temporary fixing member arranged in the slider or the case to temporarily fix the structural member of the braking device, andan attachment member to be attached to the slider or the case to firmly fix the structural member of the braking device to the slider or the case,wherein when the latch is switched from the standby position to the draw-in position, the urging force accumulated in the urging device moves the mobile body from a first position on a main body side to a second position through the actuating member, andthe draw-in unit includes a connecting portion to hold the attachment member, and the fixing ring is disposed inside the connecting portion, so that the fixing ring is arranged to temporarily fix the structural member of the braking device to the draw-in unit and the attachment member is placed over the connecting portion to firmly fix the structural member and engage with the connecting portion. 4. A slide assist device according to claim 2, wherein the convex portion is disposed on the slider to stably hold the latch in the standby position when the latch is rotated. 5. A slide assist device according to claim 4, wherein the latch has an end portion having a flat surface to contact the convex or concave portion. 6. A slide assist device according to claim 2, wherein the convex portion is disposed on a lower surface of an end of the latch. 7. A slide assist device according to claim 2, further comprising a cover disposed over the case, wherein the cover has a guide portion including a straight groove extending in a longitudinal direction of the draw-in unit and a locking groove having an L-shape on two ends of the straight groove, andthe guide portion is arranged to fit the latch, and the latch slides along the straight groove and engages with the locking groove to lock the latch. 8. A slide assist device according to claim 2, wherein the latch further comprises an assist engaging device to engage with the actuating member when the latch is in the draw-in position by a mis-actuation so as to be capable of switching the latch from the draw-in position to the standby position. 9. A slide assist device according to claim 3, wherein the structural member is a piston rod having a locking groove on an outer circumference at one end thereof to engage with the fixing ring, the connecting portion further comprises a housing portion to house the fixing ring attached to the one end of the piston rod to fix the piston rod to the draw-in unit, andthe attachment portion is arranged to detachably attach to the connection portion so that when the piston rod is temporarily fixed in the housing portion through the fixing ring, the attachment portion is placed over the housing portion to fix the braking device to the draw-in unit.
