ABSTRACT:
A vibration motor comprised of a motor body, a motor shaft projecting from the motor body, an eccentric weight attached to the motor shaft, and a mounting frame for setting the motor body on one surface of a board, wherein the mounting frame has a pair of feet straddling a motor case in its thickness direction and extending in parallel with the motor shaft and wherein a plane including the back surfaces of the pair of feet intersects with a circular orbit of the outermost point of the eccentric weight at two points, thereby enabling the vibration motor to be mounted on a thinner board, and a board mounting structure of the same.
