PURPOSE:To reduce the shift extent with a releasing action in a lock release mode by providing a member to be locked on a rocking member which can revolve freely and setting the axis of the rocking member on a line set in the same direction as the releasing direction of the member to be locked. CONSTITUTION:A holding member 2 revolves on the basis of a fulcrum 3 and is connected to a lock member via a fulcrum 4. The member 1 contains a small hole 1a and a lock part 5 formed at the side opposite to the fulcrum 4. A member 6 to be locked is set on the tip of a rocking member 17 which can freely revolve on the basis of a shaft 18 and revolved together with the member 17. Both member 6 and 17 are always energized with power P in the lock releasing direction and move forward against the power P when a driving mechanism which moves the shaft 18 is active. The shaft 18 of the member 17 is set on the same line (l) as the direction of the lock releasing power P. Therefore the fulcrum 4 is fixed on same line as the direction of the releasing power P together with the shaft 18 when the member 2 is fixed in a lock mode. |
