1. A locking device that locks a power feeding plug to a power receiving connector and locks a lid covering the power receiving connector, one of the power feeding plug and the power receiving connector including a hook, the other one of the power feeding plug and the power receiving connector including a catch, the locking device comprising: a first hook restriction member moved between a first hook lock position, at which the first hook restriction member holds the hook on the catch, and a first hook unlock position, at which the first hook restriction member permits the hook to move away from the catch, wherein when the hook moves away from the catch, the first hook restriction member moves to the first hook unlock position in cooperation with the hook;a second hook restriction member moved between a second hook lock position, at which the second hook restriction member engages with the first hook restriction member located at the first hook lock position and restricts movement of the first hook restriction member, and a second hook unlock position, at which the second hook restriction member disengages from the first hook restriction member and permits movement of the first hook restriction member;a lid restriction member moved between a lid lock position, at which the lid restriction member engages with a lid engagement member arranged on the lid and restricts opening and closing of the lid, and a lid unlock position, at which the lid restriction member disengages from the lid engagement member and permits opening and closing of the lid; anda drive source operably coupled to both of the second hook restriction member and the lid restriction member. 2. The locking device according to claim 1, further comprising a cam that moves in cooperation with the drive source, wherein the second hook restriction member is engaged with the cam and thereby moved between the second hook lock position and the second hook unlock position, while the lid restriction member is engaged with the cam and thereby moved between the lid lock position and the lid unlock position. 3. The locking device according to claim 2, wherein: the first hook restriction member is pushed by the hook and moved to the first hook unlock position when the power feeding plug is connected to the power receiving connector;the cam includes a first projection projected radially from the cam, wherein the first projection moves the second hook restriction member from the second hook lock position to the second hook unlock position as the cam rotates; andthe cam stops at a position where the first projection engages with the second hook restriction member. 4. The locking device according to claim 3, further comprising an urging member that urges the lid in an opening direction, wherein: the cam includes a second projection projected radially from the cam, wherein the second projection moves the lid restriction member from the lid lock position to the lid unlock position as the cam rotates, andthe first projection and the second projection are arranged at separate positions in the direction in which the cam rotates so that the second projection does not engage with the lid restriction member when the first projection engages with the second hook restriction member and so that the first projection does not engage with the second hook restriction member when the second projection engages with the lid restriction member. 5. The locking device according to claim 2, further comprising: a first case that accommodates the first hook restriction member and is fixed to the power receiving connector; anda second case that accommodates the second hook restriction member, the drive source, and the cam, wherein the first case and the second case are arranged at separate positions. 6. The locking device according to claim 5, wherein the second case further accommodates the lid restriction member. 7. The locking device according to claim 2, wherein the drive source includes a motor, and the motor rotates the cam in a single direction to move the second hook restriction member to the second hook unlock position and the lid restriction member to the lid unlock position at different timings. 8. The locking device according to claim 3, wherein the first projection is triangular. 9. The locking device according to claim 3, wherein: the cam includes a second projection projected radially from the cam, wherein the second projection moves the lid restriction member from the lid lock position to the lid unlock position as the cam rotates; andthe second projection engages with the lid restriction member within a rotational angular range in which the first projection engages with the second hook restriction member.
