Claims

[Scope of utility model registration request]

a synchronized slide member having a positioning portion on one side edge and capable of sliding in a predetermined direction; a lock member movable in a direction substantially perpendicular to the sliding direction of the synchronized slide member; and a synchronized slide member that moves together with the lock member; and a cam member supported by the lock member and having a cam portion and a cam shaft, and a pressing member that moves together with the lock member and presses the cam member toward the lock member to sandwich the cam member between the lock member and the lock member. Prepare,
In the device that transmits the pressing force from the push button to the pressing member by a return spring interposed between the pressing member and the push button, the return spring is a combination of a part with a dense coil pitch and a part with a sparse coil pitch. A push-button tuner characterized by comprising:
