A slide assist mechanism includes a case attached to one of a main body or a moving body; a slider disposed freely slidably in the case; a latch supported by the slider so as to be switched between a standby position which locks in a corresponding portion of the case and a draw-in position which releases the locking; a draw-in unit including an urging device; and an operation member attached to the another of the main body or the moving body and switching the latch from the standby position to the draw-in position, or switching the latch from the draw-in position to the standby position. When the latch is switched from the standby position to the draw-in position, due to an urging force which has been accumulated in the urging device, the slide assist mechanism allows the moving body to move from a first position to a second position on a main body side through the operation member. In the slider, the urging device is disposed on a lower surface side, and also one end in a sliding direction includes an attachment device for the urging device.

A slide assist mechanism according to claim 1, wherein the slider includes a supporting groove, and the latch includes a supporting shaft, which form the control device; the supporting groove has an arc-shape groove notched in an arc shape around a pivotal center of the latch; andthe supporting shaft includes a neck portion inserted laterally slidably through an entrance opening of the supporting groove, and a head portion preventing the neck portion from escaping in a state in which the neck portion is inserted through the supporting groove. 3. A slide assist mechanism according to claim 1, wherein the slider includes a shaft hole, and the latch includes a shaft portion inserted in the shaft hole, the shaft hole and the shaft portion forming the control device; the shaft portion includes a collar portion projecting circumferentially around the shaft portion and rotatably supported on the slider; andthe shaft hole includes a level difference portion fitted to the collar portion. 4. A slide assist mechanism according to claim 1, wherein the latch includes an abutting piece forming the control device; and the abutting piece projects upward from one portion of the latch and contacting freely slidably with a corresponding portion of the slider. 5. A slide assist mechanism, comprising: a case adapted to be attached to one of a main body or a moving body;a slider including a supporting groove and disposed slidably in the case, the supporting groove having an arc-shape notched in an arc shape;a latch arranged under the slider and including a supporting shaft projecting upwardly to be inserted in the supporting groove, the supporting shaft having a neck portion inserted laterally slidably through an entrance opening of the supporting groove and a head portion at one end of the neck portion to prevent the neck portion from escaping in a state that the neck portion is inserted through the supporting groove, the latch being supported to the slider switchably between a standby position where the latch is locked in a corresponding portion of the case and a draw-in position where the latch is released from locking;a draw-in unit comprising an urging device for urging the slider;an operation member adapted to be attached to another of the main body or the moving body, and switching the latch from the standby position to the draw-in position, or switching the latch from the draw-in position to the standby position; anda control device including the supporting groove and the supporting shaft, and provided between the latch and the slider such that the latch is suspended from the slider through the supporting shaft and the supporting groove,wherein the control device is arranged such that when the latch is switched from the standby position to the draw-in position, an urging force is accumulated in the urging device, and the moving body is moved from a first position to a second position on a main body side through the operation member, andwhen the latch is switched between the standby position and the draw-in position through the operation member, the control device prevents the latch from inclining relative to the slider to maintain a horizontal rotational movement of the latch. 6. A slide assist mechanism according to claim 5, wherein the arc-shape groove includes a level difference portion formed along an upper edge thereof, and the head portion protrudes circumferentially from the neck portion; and the head portion is arranged on the level difference portion to support the latch on the slider such that the neck portion passes through the supporting groove. 7. A slide assist mechanism according to claim 6, wherein the latch further comprises a shaft portion formed at one end portion thereof corresponding to the pivotal center of the latch, and a projection formed on the other end portion thereof spaced from the shaft portion, the supporting shaft being arranged between the shaft portion and the projection, and the shaft portion and the projection projecting in a direction parallel to the supporting shaft; and the slider further comprises a shaft hole formed at a portion corresponding to the shaft portion such that the shaft portion is inserted therein, and an escape groove notched outside of the arc-shape groove such that the projection is laterally slidably inserted therein through an entrance opening of the arc-shape groove, the an arc-shape groove being arranged between the shaft hole and the escape groove. 8. A slide assist mechanism according to claim 7, wherein the projection has a height higher than the shaft portion and the supporting shaft relative to a projecting direction from the latch, and the escape groove has the entrance opening larger than that of the supporting groove. 9. A slide assist mechanism according to claim 8, further comprising a cover including a guide portion and attached to the case, wherein the guide portion includes a straight-line groove and locking grooves formed at two ends of the straight-line groove, and the projection is fitted in the guide portion to slide along the straight-line groove and to engage the locking grooves to lock a sliding of the latch. 10. A slide assist mechanism according to claim 7, wherein the latch includes an inclined-surface guide portion formed at a side opposite to the projection and tapered in a direction toward the other end portion, and a concave portion connecting the inclined-surface guide portion and concaving from the side opposite to the projection to engage the operation member when the latch is improperly positioned in the draw-in position.
