By selectively pressing the push buttons 1 and 2 in the direction of arrow b, one of the sliding members 3 and 4 returns to the spring acting portion 1 of the spring 13.
8, 19 in the direction of arrow b, the pair of locking pawls 29, 30 integrally provided at the free ends of these sliding members 3, 4 are locked. It is configured to be selectively engaged and locked by a pair of engagement claws 31 and 32 that are integrally provided on the side surface of 26. However, in this case, the locking claw 2
9 and 30 are selectively locked to the locking pawls 31 and 32, the lock plate 26 moves in the direction of the arrow c, due to the cooperation with a return spring (not shown) that biases the lock plate 26 back in the direction of the arrow d.
One reciprocating motion is made in the d direction. As the lock plate 26 moves forward in the direction of arrow c, one of the previously locked sliding members 3 and 4 is unlocked and returned by one of the spring action parts 18 and 19 of the spring 13. It is moved back in the direction of arrow a.

Note that push buttons 1 and 2 of this push button device are configured as a record button, a play button, a fast forward button, a rewind button, a stop button, etc. of a tape recorder. The signal is transmitted to the mode switching mechanism of the tape recorder via the moving members 3 and 4, and the mode of the tape recorder is switched.
