サージ効果が低下することを防止できる。Further, the roller (5) is connected to the convex portion (53a) of the roller.
Since the elastic sleeve (57) is slightly pressed against the outer surface and urged outward, the lateral movement of the fir ball drive unit (6) can be effectively suppressed, and the end of the roller (5) is raised. There is almost no wear of the part (55). This is the elastic sleeve (57)
Is because the repulsive force increases rapidly when deformed beyond a certain dimension in the axial direction, so that the effect of suppressing the lateral movement of the fir ball drive unit (6) is greater than that of the conventional coil spring. There is no rattling noise, and the massage effect can be prevented from lowering.

ることを防止できるのである。Further, the outward urging force of the elastic sleeve (57) against the roller (5) is equivalent to the deformation of the sleeve (57), that is,
Since the end surface of the sleeve (57) is only slightly cut into the convex portion (53a) of the roller, the urging force can be reduced as compared with the case where the entire end surface of the sleeve (57) is deformed. For this reason,
When the roller (5) is fitted on the guide rail (22), the force for urging the roller (5) against the bottom surface of the guide rail (22) can be minimized. This allows the roller
Excessive pressure is applied to the contact portion between the raised portion (55) of (5) and the guide rail (22), so that the raised portion (55) on the end face of the roller (5) can be prevented from being worn.

It can be effectively suppressed, and there is almost no wear of the raised portion (55) on the end face of the roller (5). This is because, when the elastic sleeve (57) is deformed beyond a certain dimension in the axial direction, the repulsive force increases rapidly, so that the effect of suppressing the shaking in the axial direction, that is, the left and right direction of the fir ball drive unit (6) is the conventional effect. This is because it is larger than the coil spring, and no rattling noise is generated, and a decrease in the massage effect can be prevented. In the embodiment, the roller (5)
Although the connecting plate (53) was applied to the elastic sleeve due to the shape of the roller (5), the roller (5) bites into the end surface of the elastic sleeve (57) and slightly touches the convex portion (53a) and the guide rail ( Two

Since the end face of the sleeve (57) is only slightly cut into the connecting plate (53), the urging force can be reduced as compared with deforming the entire end face of the sleeve (57). Therefore, when the roller (5) is fitted on the guide rail (22),
The force for urging the roller (5) against the bottom surface of the guide rail (22) can be minimized. This can prevent excessive pressure from being applied to the contact portion between the raised portion (55) of the roller (5) and the guide rail (22), and can prevent wear of the raised portion (55) on the end surface of the roller (5). is there.

By rotating the screw shaft 26 with a small force, the ball drive unit 6 can be raised and lowered smoothly. still,
In this embodiment, the screw shaft (26) is positioned substantially at the center of the left and right length of the frame (21), so that the fir ball drive unit (6)
The left and right balance was achieved, but the fir ball drive unit (6)
When the weight itself is not balanced at the left and right centers, the position of the screw shaft (26) may of course be arranged not at the left and right center of the fir ball drive unit (6) but at a position where the weight is balanced. It is.

音は発生せず、静寂な運転が可能となった。When the screw shaft (26) is arranged near one side of the frame as in the conventional example of FIG. 8, abnormal noise occurs when the screw shaft (26) is rotated. Thus, when the screw shaft (26) is located in the middle of the frame (21) and the screw shaft driving motor (65) is arranged near one end of the frame (21), the abnormal noise when rotating the screw shaft is It has become so small that it can hardly be heard. In pursuit of this cause, FIG.
In the case of the conventional example, the distance between the motor (65) and the screw shaft, that is,
The length of the belt (67), the thickness of the belt, and the speed of the belt (67) are in a relationship of causing the belt (67) to resonate by the rotation of the motor (65), and the resonance of the belt (67) causes abnormal noise. I knew it would happen. When the screw shaft (26) is located at the center of the frame (21) as in the embodiment, as a result, the belt (67) is shorter than before, the resonance of the belt (67) is eliminated, and abnormal noise is reduced. It did not occur and quiet driving became possible.
