Abstract: There is provided a holding structure to hold a vibration motor on a circuit board with a sufficient holding strength using an inexpensive and simple means such as caulking and bonding and a vibration motor held on a circuit board using the holding structure. The holding structure having a holder clamps a vibration motor body having an eccentric weight at an end of the rotation shaft around the outer periphery from the outside and supports the vibration motor at the lower part.

Abstract: A weight for a vibration motor, the weight including: a resin part including: a semi-cylindrical portion having a shaft hole in which a rotary shaft is fitted and expanding radially from the shaft hole at a given center angle so as to be eccentrically weighted with respect to the shaft hole; and a pair of locking projections respectively disposed at both axial end areas of an outer circumferential surface of the semi-cylindrical portion so as to extend radially outwardly therefrom; and a metal part attached to the resin part so as to sit on the outer circumferential surface of the semi-cylindrical portion, the metal part including: a pair of locking recesses positioned and configured to correspond respectively to the locking projections of the resin portion, wherein an elevated portion formed between the pair of locking recesses makes contact with the pair of locking projections of the resin portion.

Abstract: In order to provide a vibration motor surface mounting structure capable of preventing a vibration motor from tipping over without using a part such as metal holder requiring complicated assembly, for a vibration motor having an eccentric weight mounted on the rotating shaft of the motor and mounted on a surface of a printed circuit board, a support member having extensions extending to the side of the rotating shaft on which the eccentric weight is mounted is used, a portion of this is fixed to the motor or the frame thereof, and a bottom surface including the extensions of the support member is secured to the mounting surface of the printed circuit board by soldering.

Abstract: In a vibration motor holding structure for retaining a vibration motor having eccentric weights at rotation shaft ends and holding the vibration motor on a circuit board, there is provided a metal holder having support legs provided along a part of the length of the vibration motor and protruding horizontally in the direction orthogonal to the longitudinal direction of the vibration motor on both sides thereof. Thus, the vibration motor can be prevented from falling over during the mounting process and be held on the circuit board at solder-applied positions.
