To provide a self-propelled vibratory machine capable of constraining a vibration body to prevent damage during transportation and movement without depending on the deterioration state of an elastic member.

The self-propelled vibratory machine includes: a traveling body 1; a conveyor frame 15 provided on the traveling body 1; two or more posts 38 erected on the conveyor frame 15; a hopper frame 39 constructed on the two or more posts 38; a vibration sieve body 31 elastically supported to the conveyor frame 15 through the elastic member 30; a hopper 4 supported to the hopper frame 39 to be located above the vibration sieve body 31; a support member 34 provided for the vibration sieve body 31; a stopper 46 provided for the hopper frame 39 to have a vertical positional relationship with the support member 34; and a spring cylinder 47 that biases the vibration sieve body 31 to bring the support member 34 into contact with the stopper 46.
