Claims

[Scope of utility model registration request]

A push button 3 made of a cylindrical body is inserted into the button hole 2 of the operation panel 1 so as to be pushable and rotatable against the bias of a spring 4, and a horizontal groove 5 in the circumferential direction is formed on the outer peripheral surface of the cylindrical portion of the push button 3. It consists of a cam pin 7 and a cam plate 9 which is swingably provided around a pivot 8 as a fulcrum to correspond to the cam pin 7 and the vertical groove 6 formed in the circumferential wall of the button hole. The cam plate 9 engages with the cam pin 7 to hold the push-in position when the push button is pushed in, and is released when pushed again to release the push-in position, and the push button is rotatable between the push-in position and the push-back position. The push button 3 is provided with two opposed guide cams 10 and 11, and the push button 3 is provided with a mechanism for locking and releasing the lock so that the push button 3 cannot be pressed again in a predetermined rotation range, and a protrusion 3b and an operation panel 1. 1. A locking device for a push button operation mechanism, characterized in that it is constituted by a stepped notch 1d provided in a button guide 1a.
