Abstract
A vibration generator includes a housing, a vibrating body arranged inside of a circumferential wall portion of the housing, and a band-like leaf spring arranged between the vibrating body and the circumferential wall portion. The leaf spring includes a connection portion connected to the vibrating body, an attachment portion attached to the circumferential wall portion of the leaf spring and an intermediate portion formed between the connection portion and the attachment portion to extend around the vibrating body. The connection portion and the attachment portion are arranged at one transverse side and the other transverse side of the vibrating body along a direction intersecting a vibration direction of the vibrating body. The intermediate portion is arranged in a vibration-direction outer region of the vibrating body and formed in a single layer to extend across the vibration direction of the vibrating body.
