The working lever is energized in a manner to be retracted in the casing and a lock piece 4 to lock a member is disposed in the casing and opposite to the working lever. Its upper part is protruded from the upper part of the casing and situated in a manner to make contact with and separate from the working lever. The locking piece is energized against the working lever side and its upper part is situated in a state to make contact with the working lever. A protrusion part 12 corresponding to an expansion part formed at the working lever is formed at the lower part of the lock piece. The protrusion part is engaged with the expansion part when the working lever is pulled upward against energization. The locking piece is pressed against the locking piece and its upper part is separated away from the working lever and the locking state of the member locked at the locking piece is released.
