1. A vibration generating device, comprising:
a stationary body including a bottom surface;
a movable body disposed in an upper space of the bottom surface; and
an elastic support disposed between the stationary body and the movable body and configured to support the movable body so as to be vibratable in a forward-backward direction with respect to the stationary body, wherein
the elastic support includes
a fixed portion fixed to the bottom surface,
an upright portion extending upward from the fixed portion,
an elastically deformable portion extending from the upright portion in a leftward-rightward direction, and
a movable body-attaching portion that extends from the elastically deformable portion and to which the movable body is attached,
the elastic support includes a projection extending from the upright portion in the leftward-rightward direction at a position in the upright portion, the position being different from a position in the upright portion at which the elastically deformable portion extends from the upright portion in the leftward-rightward direction, and
a buffer is included between the projection and the stationary body.
