Abstract
In a push-button tuner including a tuning slide member which has a positioning portion in one side edge and which is slidable in a predetermined direction, a lock member which is movable in a direction orthogonal to the sliding direction of the tuning slide member and which is provided with cam member grasping means, and a cam member which is turnably supported by the lock member. The cam member comes into engagement with the positioning portion of the tuning slide member and has its position in its turning direction fixed by the cam member grasping means. The positioning portion of the tuning slide member is provided with an elastic piece. When the lock member has been thrust to the tuning slide member, the cam member comes into pressed contact with the elastic piece, and the elastic piece retreats. Thus, the abutting force between the tuning slide member and the cam member is lightened.
