Claims (1)

[Scope of utility model registration request] Either a pendulum ball row formed by suspending a plurality of balls with thin wires from two beams so that the centers of each of the balls are on the same horizontal line and adjacent balls are in contact with each other, or this pendulum ball row A piezoelectric element is fixed to a support by attaching a patch plate to the vibrating surface so that the direction of vibration caused by applying a pulse voltage coincides with the horizontal straight line at a position away from one end, and a piezoelectric element that is in contact with the patch plate and is horizontally aligned with the horizontal line. and a batted ball suspended from the beam at a height such that when swung in a plane including a straight line, the ball collides with the ball at the end of the backing plate side of the pendulum ball array, and a pulse voltage is applied to the piezoelectric element. The interior toy is characterized in that the batted ball and the end of the pendulum ball row opposite to the contact plate are automatically caused to swing repeatedly.
