And a positive terminal body having elasticity provided opposite to the second holding portion so that the side end face is pressed by the second holding portion. A side surface electrically connected to the motor minus electrode is elastically pressed and held by the first holding portion and the minus terminal body, and further, the motor plus electrode in a direction orthogonal to the side surface. Side end surface which is electrically connected,
It is elastically pressed and held by the second holding portion and the plus terminal body. At the time of assembling, the motor may be inserted against the elasticity of the minus terminal body and the plus terminal body. Electrical connection is made stable by the elastic contact of the motor negative electrode and the negative terminal body and the motor positive electrode and the positive terminal body at the same time as the assembly. There is no need to perform this, and assemblability is improved.

[0007] Further, the present invention provides a common terminal by using at least one of the negative terminal body and the positive terminal body as a power supply terminal installed in an apparatus main body on which a motor is mounted. Thus, the number of parts can be reduced and the terminal structure can be simplified.

The present invention is also effective when applied to holding a cylindrical vibration motor installed in a small radio receiver.

And a side end surface 13 electrically connected to the positive electrode of the motor in the direction.

The small radio receiver main body 14 as a device main body on which the motor main body 11 is installed has a plate-shaped negative terminal 15 having a spring property and an upper end portion 15a bent in a V shape.
And a plate-shaped plus terminal 16 having spring properties and having an upper end 16a bent. The minus terminal 15 and the plus terminal 16 are connected to a power supply (not shown) mounted on the small wireless receiver main body 14.

Further, the small radio receiver main body 14 is provided with a distance slightly smaller than the diameter of the peripheral side surface 12 of the motor main body 11 so as to protrude so as to face the pressed portion of the minus terminal 15. Pressing the plus terminal 16 with the motor holder 17 which is a first holding portion having a small curved surface portion 17a formed at an upper end portion, with a distance slightly smaller than a longitudinal dimension orthogonal to the peripheral side surface 12 Small plate-shaped ribs 18 are provided as second holding portions protruding so as to face the portions.

Therefore, as shown in FIG. 2, when the motor main body 11 is incorporated into the small radio receiver main body 14, the motor main body 11 is connected to the minus terminal 15, the plus terminal 16 and the motor holder 17 on the small radio receiver main body 14. , The negative terminal 15 and the positive terminal 16
The bent portion at the upper end portion moves outward due to the pressing force of the motor body 11, and the motor body 11 enters the space S. When the motor main body 11 is completely inserted into the space S, as shown in FIG. 1, the minus terminal 15 presses the peripheral side surface 12 of the motor main body 11 against the motor holder 17 by its own elastic force. Presses the side end surface 13 of the motor body 11 in the direction of the rib 18 by its own elastic force.
Due to the pressing of the plus terminal 16, the end face opposite to the side end face 13 comes into contact with the rib 18. Further, the upper end portion 15a of the minus terminal 15 bent in the shape of a letter and the small curved surface portion 17a of the upper end portion of the motor holder 17 hold and press down the peripheral side surface 12 of the motor main body 11.

Accordingly, the motor body 11 is pressed and clamped in the space S by the minus terminal 15 and the motor holder 17 to prevent the motor body 11 from slipping out in all directions perpendicular to the longitudinal direction and to prevent rattling. In this state, the negative terminal 15 is always in elastic contact with the peripheral side surface 12 electrically connected to the negative electrode of the motor, so that a stable power supply state can be achieved. Further, the motor body 11 has a positive terminal in the space S.
16 and the ribs 18 hold the longitudinal direction of the motor in such a manner that the longitudinal direction of the motor is prevented from coming out and rattling, and the plus terminal 16 is connected to the side end surface 13 electrically connected to the plus electrode of the motor. Since it is always in elastic contact, a stable power supply state can be achieved.

The minus terminal 15 and the plus terminal 16 are for supplying power from the small radio receiver main body 14 side, and both terminals 15 and 16 have a structure provided independently of the power supply. Also, the negative terminal 15 and the positive terminal
