As shown in FIG. 1, the pair of vibrating massaging devices 21A and 21B in which the motor mounting frame 41 is vibration-proofly fixed to the case member 2 has the vibrator 55 mounted on the leg 9a. Inside the quadrangle formed by the straight lines ad connecting 9d to 9d, for example, they are arranged near the legs 9b and 9d. Moreover, as shown in FIG. 1, the vibrators 55 of both the massaging devices 21A and 21B are provided so that the large-diameter projections 53 of the head 52 are close to each other and the small-diameter projections 54 are arranged to be far from each other. There is. The interval between the protrusions 53 is set to be approximately the same as the interval between the acupuncture points located so as to sandwich the spine of the back acupuncture points on both sides of the user's spine.

Due to the mutual arrangement of the heads 52, when the user sits on a chair and massages the arch of the foot, a protrusion 54 having a small diameter is mainly used to eliminate contact between the both feet, and at the same time, to the arch of the foot. It is possible to prevent the arch from being excessively overloaded by depositing the weight on the chair, even though the protrusion 54 having a small contact area is used for the massage. Further, when massaging an affected area such as the back or the waist, a large-diameter projection 53 is mainly used to secure a large contact area to the affected area, and it is possible to prevent the affected area from becoming too painful due to the effect of weight. .

Moreover, the pair of vibration type abraders 21A and 21B are arranged in an inverted C shape in FIG. 1 so that the vibrators 55 are narrow and the motors 42 are wide. The control device 22 is attached to the case member 2 by utilizing the space between the containers 21A and 21B. As a result, a large installation space for the control device 22 can be secured, so that the printed wiring board 24 can be made large, and the circuit pattern can be easily designed. Further, since the control device 22 and the motor 42 can be provided at positions close to each other, the length of the lead wire extending between them can be shortened.

As representatively shown in FIG. 6, the heads 52 of the vibrators 55 included in the massaging devices 21A and 21B having the above-described configurations are separately passed through the through holes 11a and 11b, respectively, and the main body case 1 Is projected out of. The head 52 of the vibrator 55 is always in contact with the inner surface of the cover 12 by the spring force of the second coil spring 49, and pushes up the cover 12 to maintain the tension state.

As shown in FIG. 4, the longitudinal distance E between the pair of vibrators 55 and one end of the main body case 1 on the concave portion 7 side is equal to that of the pair of vibrators 55 and the concave portion 8 side of the main body case 1. It is smaller than the longitudinal distance F between the other end. The distance E is set to such a length that the pair of vibrators 55 correspond to the height of the waist of the sitting user when the main body case 1 is erected with the concave portion 7 facing downward. F is set to a length such that the pair of transducers 55 correspond to the height of the portion between the body case 1 and the scapula hips on the back of the seated user when the body case 1 is erected downward. ing.

As shown in FIGS. 1 and 6, elastic bodies 61 made of sponge rubber or the like are sandwiched between the bottom wall of the case member 2 of the main body case 1 and the vibrator 55. . The elastic body 61 is elastically deformed while being compressed when the vibrator 55 is pushed by the affected area, and the elastic force biases the vibrator 55 toward the affected area. Reference numeral 62 in FIGS. 1 and 6 denotes a connecting plate which is laid across a pair of vibrators 55, and prevents the vibrators 55 from being twisted due to the second coil spring 49, and corrects the affected parts. It is provided to obtain the pressing state. Further, reference numeral 63 in FIG. 1 denotes a reflection type photo switch fixed to the inner surface of the case member 2, which is turned on when the reflected light from the connecting plate 62 is received and is a motor for both the abraders 21A and 21B. The 42 is supposed to start at the same time.

The massaging device M having the above configuration is mainly used as a foot massager. At this time, the user C sits on a chair as shown in FIG. 9 (A), and puts the arches of both feet on the pair of transducers 55 through the covers 12 separately. Then, as the vibrator 55 is pushed down by the weight of the foot, the connecting plate 62 intersects the optical path of the photo switch 63, so that the switch 63 is turned on by receiving the reflected light from the connecting plate 62. As a result, the motors 42 of the pair of massaging devices 21A, 21B are activated.

As a result, the output shaft 42a of the motor 42 rotates the eccentric weight 45 via the first coil spring 44, so that the entire vibrator 55 vibrates with this rotation. 52 is transmitted to the arch through the cover 12 so that the soles of both feet can be massaged respectively.

When used as a foot massager in this way, the remote control storage recess 4 (whether or not the remote controller 31 is stored) between the pair of vibrators 55 is seated on a chair. The user's C foot can be used as a guide when placing the foot of the user C on a fixed position, that is, on the pair of massage parts 5 and 6, respectively. It is useful. Even if the remote controller 31 is housed in the remote controller housing recess 4, since the thickness of the remote controller 31 is smaller than the depth of the remote controller housing recess 4, the remote controller 31 housed in the remote controller housing recess 4 is It does not get in the way when the foot is placed on the main body case 1 by being projected onto the remote control storage recess 4. Therefore, both feet can be easily set (placed) on the pair of vibrators 55, respectively.

Further, as shown in FIG. 9B, the calves of both feet can be massaged by placing the calves of both feet separately on the pair of transducers 55 while sitting on the floor. .

Then, as shown in FIG. 9 (C), in the state of sitting on the chair, the massage device M is inserted between the back of the chair and the back of the chair, with the concave portion 7 thereof facing upward, By leaning on the back, the motors 42 of the pair of massaging devices 21A and 21B can be activated and the back can be massaged by the pair of vibrators 55.

Similarly, the massaging device M is inserted between the backrest and the waist of the chair with the concave portion 7 thereof facing downward, and leans against the backrest to vibrate the pair of vibrators 55, respectively. You can massage the lower back.

When using FIG. 9 (C), the remote controller 31 is detached from the remote control accommodating recess 4 and placed at the user's C hand. Therefore, if the operation mode is changed during this use, the operation can be performed by hand operation, and the massaging device M can be taken out from between the backrest of the chair and the upper body of the user C to operate the operation mode. There is no need to change the mode. Also, when using FIG. 9B, it is possible to drive with the remote controller 31 at hand.

In the use of the massaging device M as described above, a pair of vibrating massaging devices 21A and 21B are provided, and the pair of vibrators 55 are individually driven by the power of the respective motors 42. Unlike the case where a plurality of vibrators are driven by, the power of the motor is not distributed to each vibrator according to the number of vibrators, and therefore the affected area can be strongly massaged by the pair of vibrators.

In addition, the vibrators 55 of the pair of vibration type massagers 21A and 21B are spaced apart in conformity with the intervals of the user's back and waist pots, and the vibrators 55 are connected to the four legs 9a to 9d. Since the pair of massaging devices 21A and 21B are arranged inside the quadrangle formed by the straight lines a to d that connect them, and the pair of massaging devices 21A and 21B are built in the main body case 1, put the feet on the pair of vibrators 55, When using the massaging device as a foot massager, the posture of the body case 1 can be kept stable.

That is, by arranging the pair of vibrators 55 with respect to the four legs 9a to 9d provided on the main body case 1 as described above, the point of action of the load applied to the massaging device M by the foot can be changed by the way of placing the foot. In any case, it can be formed inside a quadrangle formed by a straight line connecting between the four legs 9a to 9d protruding from the bottom wall of the main body case 1. Therefore, there is no problem that the body case 1 tilts depending on how the foot is placed, and the stability of the posture of the body case 1 when the foot is placed on the vibrator 55 can be secured, which is convenient for use.

The present invention is not limited to the above-mentioned embodiment. For example, the through holes 11a and 11b of the main body case 1 may be one through hole. Alternatively, the cover 12 may be omitted and the affected part may be directly contacted with the vibrator 55.
