A lock device locks a lid, which protects the inlet, and a power supplying plug. The lock device includes a helical gear rotated by the motor. A helical gear is connected to a control shaft. The control shaft is moved to a hook lock bar lock position when the helical gear rotates counterclockwise from the reference position. The helical gear is connected by a transmission member to a lid lock bar. The lid lock bar is constantly urged toward a lid lock position by a coil spring. When the helical gear rotates clockwise from the reference position, the lid lock bar moves to the lid unlock position against the urging force of the coil spring.

1. A lock device that locks a lid and a power supplying plug, wherein the lid protects a power reception connector, the lock device comprising: a plug restriction member that moves between a plug lock position and a plug unlock position, wherein the plug restriction member restricts removal of the power supplying plug from the power reception connector at the plug lock position, and the plug restriction member permits removal of the power supplying plug from the power reception connector at the plug unlock position;a lid restriction member that moves between a lid lock position and a lid unlock position, wherein the lid restriction member engages the lid and restricts opening of the lid at the lid lock position, the lid restriction member permits opening of the lid at the lid unlock position, and the lid restriction member is constantly urged toward the lid lock position; anda drive mechanism including a drive source and a rotating body, wherein the drive source generates drive force and rotates the rotating body in first and second directions from a reference position,wherein the drive mechanism is directly or indirectly connected to the plug restriction member to move the plug restriction member from the plug unlock position to the plug lock position when the rotating body rotates from the reference position in the first direction,the drive mechanism is directly or indirectly connected to the lid restriction member to move the lid restriction member from the lid lock position to the lid unlock position against an urging force acting on the lid restriction member when the rotating body rotates from the reference position in the second direction,when closing the lid with the lid restriction member held at the lid lock position, the lid restriction member engages the closing lid and moves toward the lid unlock position thereby permitting the lid to close, andthe lid restriction member is formed to be returned to the lid lock position by the urging force at a timing at which the lid reaches a close position. 2. The lock device according to claim 1, further comprising a transmission member connected to the rotating body and the lid restriction member and formed to generate linear motion when the rotating body rotates, wherein the lid restriction member is located in a movement path of the transmission member, andthe lid restriction member is moved by the linear motion of the transmission member between the plug lock position and the plug unlock position. 3. The lock device according to claim 1, wherein the power supplying plug includes a movable hook,the power reception connector includes a cooperative member that moves in cooperation with the hook and a hook seat, which engages the hook, andthe plug restriction member rotates integrally with the rotating body in a range between the plug lock position, which is located on a movement path of the cooperative member, and the plug unlock position, which is separated from the movement path of the cooperative member. 4. The lock device according to claim 2, wherein the transmission member includes a first valley formed by a first slope and a second slope that are inclined relative to a movement direction of the transmission member, andthe lock device includes a follower pin that pushes the first valley in a direction perpendicular to the movement direction of the transmission member. 5. The lock device according to claim 4, wherein the transmission member includes a second valley and a ridge,the second valley is formed by a third slope and a fourth slope that are inclined relative to the movement direction of the transmission member, andthe ridge is formed by the second slope and the third slope. 6. The lock device according to claim 1, further comprising a manual operation portion manually operated to rotate the rotating body from outside the lock device. 7. The lock device according to claim 1, wherein when the lid restriction member is pushed by the lid at the lid lock position as the lid closes, the lid restriction member temporarily moves from the lid lock position toward the lid unlock position without using the drive force of the drive source to permit closing of the lid. 8. The lock device according to claim 1, wherein the power reception connector is installed in a vehicle including a travel motor and a battery that supplies the travel motor with power. 9. A lock device mounted on a vehicle, wherein the vehicle includes a battery, a travel motor powered by the battery, a power reception connector for a power supplying plug that charges the battery, and a lid for closing the power reception connector, the lock device comprising: a movable stopper pivotally supported by the power reception connector to engage with and disengage from a power supplying plug connected to the power reception connector;a rotating body connected to a drive source and rotated by the drive source in first and second directions from a reference position;a control shaft coupled to the movable stopper and the rotating body and rotated by the rotating body from a plug unlock position to a plug lock position when the rotating body rotates from the reference position in the first direction, wherein the control shaft is shaped to move the movable stopper to a position at which the movable stopper engages the power supplying plug when the control shaft rotates to the plug lock position; anda lid lock bar coupled to the rotating body and linearly moved by the rotating body from a lid lock position to a lid unlock position against an urging force acting on the lid restriction member when the rotating body rotates from the reference position in the second direction, whereinwhen the lid is manually operated to close the power reception connector while the lid lock bar is held at the lid lock position, the lid lock bar is urged toward the lid unlock position by the closing lid thereby permitting the lid to close, andthe lid lock bar is formed to be returned to the lid lock position by the urging force at a timing at which the lid reaches a close position.
