Referring to FIGS. 5 to 7, the structure of another head cap 70 that can be mounted on the head body 22 in place of the head cap 28 shown in FIG. 1 will be described. The head cap 70 is made of a conductive material similarly to the head cap 28, and the screw 2
2a, and female screws 70a, 7
.. Are engraved a plurality of times. These female screws 70a, 70
The diameter of a ... is the shaft portion 72 of a generally marketed cotton swab 72.
It is set to be the same as or slightly thicker than a. Therefore, as shown in FIG. 6, the shaft 72a of the cotton swab 72 is cut near the head 72b, and as shown in FIG. 7, the cut portion is inserted from the outside into the female screw 70a of the head cap 70 with the cut end pointed and rotated. Let it. This insertion and rotation causes the swab 7
The cotton of the second head 72b is formed into the screw shape of the female screw 70a, and is screwed as if it were a bottle, so that it does not easily move at least in the pulling-out direction.
The heads 72b, 72b,... Of the cotton swabs 72, 72,... Are immersed in water or the like so as to appropriately contain water, and the water is used to obtain conductivity so that low-frequency pulse electric signals are transmitted.
The heads 72b, 72b,... Of the swabs 72, 72,.

In such a configuration, one of the head caps 28 or 70 is selected as desired and the head main body 22 or 70 is selected.
, And the hand grips 14, 14 are grasped with one hand, and the pins 30, 30,... Or the implanted cotton swabs 72, 72,.
The power switch 4 in contact with the skin to be stimulated.
When 2 is input, an electric signal of a low-frequency pulse is given to the contacted skin together with the vibration. Here, when the vibration is given together with the electric signal of the low-frequency pulse, the tingling sensation caused by the electric signal of the low-frequency pulse is reduced as if by the stimulation by the vibration, and the user feels discomfort. Less, and can be used safely by women. Furthermore, if the user feels resistance in contacting the pins 30, 30,... Made of conductive material with sensitive parts such as the face, the head cap 70 is selected and the heads 72b, 72b. It only has to be in contact with the skin. The cotton swabs 72, 72... Can be applied to the skin in the same manner as the pins 30, 30. It can give a sense of security.

The motor 24 as a vibrating means has a rotating shaft disposed substantially parallel to the longitudinal direction of the hand grips 14, 14, so that one end of the motor 24 is swung with respect to the hand grips 14, 14. The movement is such that the tip of the handgrips 14 is swung as if it were a fulcrum at the point where the handgrips 14 are gripped, and the vibration applied to the gripping hand is small. This is a remarkable difference as compared with the case where the motor 24 is arranged with its rotation axis orthogonal to the longitudinal direction of the handgrips 14, 14. Further, the handle portion is hollowed at its middle portion by the hand grips 14 and 14 to reduce the weight, and the head portion is configured to be relatively heavy with respect to the handle portion. Therefore, the motor 24 is provided. The weight of the device is concentrated at the location, and the larger the mass, the more the pins 30, 30,.
The vibration applied to 2, 72... Becomes strong.

In addition, the handgrips 14, 14 are used as one electrode and the pins 30, 30,... Or the swabs 72, 72. , 14 and the pins 30, 30,... Or the cotton swabs 72, 72,... When the pins 30 are brought into contact with the skin of another person, an electrode may be wound around the arm or the like of the person to be massaged and electrically connected to the terminal 56 of the control unit 34.

In the above embodiment, the oscillating means performs a circular motion constituted by an eccentric motor 24 having a weight 26. However, the present invention is not limited to this. Vibration means may be used. Then, the vibrating means is arranged in a direction in which the vibration direction (the direction of the plane of the rotation locus in the case of circular movement, the direction of movement in the case of reciprocating movement) is substantially orthogonal to the longitudinal direction of the handgrips 14, 14. For example, hand grip 14, 14
Vibration can be reduced. Further, the handle portion is entirely formed of an insulating resin, and the hand grip 14,
An electrode layer made of a conductive material may be provided on the outer surface of a portion corresponding to 14 by plating or the like to form an electrode. Further, the number of pins 30, 30,... To be protruded and the number of heads 72b, 72b,.
