Abstract:
A vibrating motor includes a stationary portion, and a movable portion able to vibrate with respect to the stationary portion along a center axis extending in a vertical direction. The stationary portion includes a bearing portion which supports the movable portion to be able to vibrate along the center axis and has a tubular shape extending along the center axis, and a coil which directly or indirectly opposes at least a portion of the movable portion in a radial direction. A lower end portion of the bearing portion has a tubular shape extending along the center axis. A communication hole which penetrates in the vertical direction and allows an outside of the bearing portion and an inside of a portion above the lower end portion of the bearing portion to communicate with each other is provided on a radially inner side of the lower end portion.
