PURPOSE: To facilitate proper operation of a push button. CONSTITUTION: A push button 14 coupled to the tip part of a handle 8 through a transverse pivot 13 and a lock claw part 11 is arranged at the tip part of a leg part 10 protruded from the back side of a push button 14. Since a support part 20 with which the lock claw part 11 is engaged is formed in a protruding manner on a horizontal passing through the transverse pivot 13, the direction of reaction exerted on the lock claw part 11 through operation by the spring reaction force of a spring 9 for drive arranged between the handle 8 and a locking shaft 5 is in the horizontal direction to a pivot 13, and the rotation force of the push button 14 by a spring reaction force is not generated. |
