ABSTRACT:
In a pushbutton tuner wherein cross arms are mounted with their flat surface parallel with the surface of the tuner base, a cross arm mechanism includes a pivotally supporting portion of a frequency setting member inserted in an engaging hole of a fixing plate mounted along the cross arm, a slit which is formed in the fixing plate so as to open at one end of the same to be inserted in the pushbutton extends to a hole formed in the same by passing through the engaging hole, and a pair of side faces for receiving a force which narrows the slit are formed at both sides of the end of the fixing plate where the slit opens, so that contacting portions formed on a slide member slidable in response to advance of the pushbutton come to stress the side faces.
