Abstract
There is provided a vibration generation device superior in responsivity compared to the related art. The vibration generation device includes a stator, a rotor provided to the stator so as to be able to rotate around the central axis, and having a weight having a gravity center at a position shifted from the central axis, and an air resistance reduction part provided to the weight, and reducing the air resistance to the weight when the rotor rotates. The weight is formed to have a semicircular shape viewed from the axial direction, and the air resistance reduction part has an arcuate part adapted to connect an end edge on the upstream side in the rotational direction of the rotor in the outer circumferential surface of the weight and an end edge on the downstream side in the rotational direction to each other so as to form a circular arc shape.
