Note that the drive device 56 can be remotely operated by a switch dex (not shown).

Next, the case where the pine surgery device 1 having the above structure is used will be explained in terms of L/l. When the user lies face up on the massage device 1, the user operates a switch box (not shown) to activate the drive source 64 of the drive device 56. This drive source 64 operates and outputs i! When the '1 III 66 rotates in the direction indicated by the arrow X in FIG. The driving data IJ 80 of No. 3 rotates in the opposite direction. Therefore, the pair of belts 86 are respectively wound around the first driving pulley 70 and the fourth driving pulley 84, and their widths ((accordingly, the second driving pulley 76 and the third driving pulley 84) Since the belt 86 is fed out from the fifth pulley 80, the portion of the belt 86 inserted into the upper passage 2θ of the guide rail 10
The vehicle travels in the direction shown by arrow Z in the figure. Belt 8 like this
6 runs, the pair of holders 90 interlocks with the running of the belt 86, so a plurality of pine surge rollers 118 provided on the inner shaft 92 of the holders 90 move the outer fabric 162.
11, the protrusion 12θ hits the back of the user.

On the other hand, when the output shaft 66 rotates in the direction of arrow X, the first mounting shaft 72 rotates in the direction of arrow Y, and the control device 1
Twenty-four disk-like bodies 126 are interlocked. The plate-shaped body 126 is indicated by the arrow Y
When rotated in the direction, the shaft-shaped body 146 engaged with the eleventh and second guide grooves 130 and 132 of the plate-shaped body 126 moves relatively along the guide grooves 130 and 132, and the frame 142 It rotates in the direction shown by arrow T in Figure 12. Then, due to the rotation e of the plate-like body 126, one of the shaft-like bodies 146 engaged with the first guide groove 130 is displaced by the first step portion 134 in the direction of protruding from the first guide groove 130. When this happens, one leaf spring 144 that spans this shaft-shaped body 146 is elastically deformed as shown by the chain line in FIG. 14, thereby operating the first limit switch 152. Then, the rotation direction of the output shaft 660 of the drive source 64 is changed by the signal from the first limit switch 152, so that the running direction of the portion of the belt 86 inserted into the upper passage 20 is opposite to the direction of arrow Z. Become. Therefore, since the pair of holders 9o are interlocked with the running of the belt 86, the user is pine-surged by the pine-surge roller 118. Also, at this time, the plate-shaped body 126 is moved in the opposite direction to the tip Jν,
In other words, since it rotates in the opposite direction to arrow Y, the frame 14
;Jfi arrow Rotate in the same direction as the arrow. And the second
When the other shaft-like body 146 engaged with the guide groove 132 is displaced by the second step 136, this shaft-like body 14
The other leaf spring 144 to which 6 is attached is elastically deformed as shown in FIG.
Activate. Then, the second limit switch 154
Since the rotational direction of the output shaft 66 of the 5+4 mover 64 is changed by the signal from the back, the running direction of the pair of holders 9o becomes the Z direction again.

In this way, the pair of holders 9o are connected to the first limit switch 152 or the second limit switch 15.
4 is reciprocated over a distance corresponding to the rotational speed of the plate-like body 126 that is activated.

By the way, the length of the belt 86 wound around one driving pulley and the length of the belt 86 fed out from the other driving pulley are such that the outer diameter of the winding pulley gradually increases.
Since the outer diameter of the pulley that is being wound up gradually becomes smaller, the two do not match. Then, belt 8 is adjusted according to the difference.
Tension is generated at the guide rail 10, and this tension is applied to the guide rail 1o via the support pulley 48 and the frame 42, so there is a risk that the guide rail 10 will warp. However, the guide L/ −/l/ 10 Vj, g, i
Is the a side the base? The other parts are held slidably by the support 28, and since it is molded from synthetic resin (C), the length dimension is reduced by the tension and does not warp. .therefore,
The smooth running of the holding body 9o along the guide rail lθ is not impaired.

In addition, when the pine surge device B is not used, it can be removed from the middle part in the longitudinal direction of the base body 2, as shown in Figure 16.
