Patent ID: 8206172

Claim:
A plug lock structure that locks a power feeding plug to an inlet, which is fixed to a power feeding subject, wherein the inlet includes a catch, and the power feeding plug includes a hook, which can be hooked to the catch, and an operation portion, which separates the hook from the catch to unhook the hook, the plug lock structure comprising: a lock member that is pivotable in a direction in which the lock member forces the hook against the catch with an urging force, wherein when the hook moves away from the catch, the lock member is pivoted in a direction in which the lock member moves away from the catch together with the hook; and a lock block that moves between a first position, at which the lock block permits pivoting of the lock member when the hook moves from a state hooked to the catch, and a second position, at which the lock block restricts pivoting of the lock member by contacting the lock member when the hook moves from the hooked state.
