In the massage device M having the above structure, when the first drive source 44 is operated and the drive pulley 46 is rotationally driven in the clockwise direction indicated by arrow A in FIG. 5, first and second timings are obtained. The driven pulley 35 is also rotationally driven in the clockwise direction via the belts 49 and 52. The rotation of the driven pulley 35 is transmitted to the support shaft 3 via the gear train, and
It is also transmitted to the first driven shaft 34a via the one-way clutch 36.

When the support shaft 3 is rotationally driven, the mounting body 9 in which the massage body 15 is supported by the cam body 4 mounted on the support shaft 3 is eccentrically rotated according to the eccentricity e and tilted. The support shaft 3 swings in the axial direction according to the angle θ. That is, the pair of massaging bodies 15 are driven in the width direction along the axial direction of the support shaft 3 and in the vertical direction intersecting the axial line, and kneading on a plane to draw a loop-shaped locus shown by T in FIG. As we exercise, we rub and massage the user's body.

The first driven shaft 34a is rotationally driven together with the support shaft 3 via the one-way clutch 36, so that a third rotating body integrally provided on the first driven shaft 34a. 32 is rotationally driven. This third rotating body 3

Thereby,
Since the rolling guide 17 provided in the middle of each drive shaft 25, 26 eccentrically rotates (elliptical movement), the second ring body 16 provided on the rolling guide 17 also eccentrically rotates. Since the arm body 14 connected to the second ring body 16 is interlocked with the eccentric rotation, this arm body 1
The massaging body 15 provided at one end of the arrow 4 is indicated by an arrow Z in FIG.

If the ratio of the rotational speeds to 5, 26 is set to, for example, 1:20, the massaging body 15 moves in the vertical direction during one loop-shaped kneading motion shown by T in FIG. It will reciprocate 20 times and perform a striking motion.

The tapping motion of the pair of massaging members 15 is 180 degrees out of phase, so that the user can
The user will be hitting the part receiving the heat alternately, which also gives the user a comfortable massage effect.

Drive pulley 4 by the first drive source 44
When the rotation direction of 6 is opposite to the direction of arrow A, the one-way clutch 36 provided between the first driven pulley 35 and the first driven shaft 34a is attached to the first driven shaft 34a. Since it runs idle, only the support shaft 3 is rotationally driven through the worm gear train. Thereby, a pair of massaging bodies 1
5 is driven in the width direction shown by the loop-shaped locus T and in the vertical direction, and is not driven in the vertical direction. Therefore, the user is given only the massage by the rubbing motion. . That is, the user can select the massage by the hitting motion.

When the screw shaft 22 is rotated by operating the second drive source 58, a pair of mount plates screwed to the right screw portion 22a and the left screw portion 22b formed on the screw shaft 22. It is possible to drive the spout 9 in the direction of approach or in the direction of separation.

A massage body 15 is integrally attached to the pair of mount bases 19 via an arm body 14. Therefore, when the mount base 9 is driven, the message body 15 is interlocked with the mount base 9 and slides along the axial direction of the support shaft 3.
The distance between the body 15 can be adjusted. That is, by adjusting the interval between the pair of masage bodies 15 according to the physique of the user who receives the masage and the site where the masage is received, the masage can be received comfortably and effectively.

The distance between the pair of massaging members 15 is set to the maximum and the minimum by a pair of limit switches 66 provided on the inner bottom portion of the base 1. Therefore, the second drive source 54 is excessively operated in the separating direction, and the pair of mounting members 9
Hit the side walls of the base 1 or use a pair of mount bases.
It is possible to prevent the gas 9 from coming too close.

In the above embodiment, the striking motion, which is the vertical movement of the massager, applies the driving force of the first driving source to the first driving shaft and the second driving shaft via the one-way clutch. I tried to communicate. That is, although the support shaft and the first and second drive shafts can be driven by the first drive source, the support shaft and the first and second drive shafts are driven by separate drive sources. It may be configured.

Further, although the massage body is fixedly provided on the arm body, it may be formed in a roller shape so as to be rotatable. By doing so, when the massage device is provided on a chair or a mat so that it can travel freely as shown in FIGS. 9 and 10, the travel can be performed smoothly.
