Description of the invention (l2 After the belt 15 is moved, the walking is linked to a pair of roller units 2 1. Thus, the lift The users on the outer packaging 20 are massaged by the massage rollers 68 and 69 provided inside and outside each roller unit 21, and are massaged by the vibration of the vibration device 81 provided on one of the roller units 21. 81 is attached to the first and second mounting portions 75 and 77 of the supporting member 73 and the restricting member 76. To this end, after a user's load is applied to the vibrating device 81 through the outer package 20, the vibrating device 81 is supported by The spring force of the member 73 is elastically pushed to the back of the user, and at the same time, the restriction member 76 is elastically deformed in accordance with the uneven shape of the back of the user, and is elastically inclined to the left and right along the axis direction of the roller shaft 51 As a result, since the vibration device 81 is reliably contacted to the back of the user with a certain pushing force by the spring force of the support member 73 and the restriction member 76, the vibration Device 8 丨 The back of the user is massaged. When the load applied to the vibration device 81 is biased in one end side and the other end side of the long hand direction along the roller axis 51, the As described above, the vibration device 81 is inclined to the left and right while elastically deforming the restricting member. Even if the vibration device 81 is inclined to the left and right direction, the restricting member 76 can be elastically deformed. The restricting member 76 is elastically deformed in the left and right directions. The winding portions 76 a at both ends are not restricted to the roller shaft 51 and cannot be rotated, and can maintain the state of rotation. Therefore, the roller shaft 51 can be prevented from following the restricting member 76 by the vibration of the vibration device 81. The vibration is in the up-down direction, so the roller unit can be prevented. 21 This paper size applies the Chinese national standard A4 specification (21〇 > < 297mm) 16 ........ .... Installation-(Please read the precautions on the back before filling this page) Order:: line 516956 A7 B7 V. The vibration of the invention description (IS). It (Please read the precautions on the back before filling this page ) As shown in Figure 14, The width dimension in the axial direction of the roller shaft 5 J. Of the restriction member 76 is set to be larger than the width dimension of the branch member 73, that is, the width dimension of the first mounting portion 75. In this embodiment, The length of the vibration device 81 is set to be approximately the same as that of the frame 82 of the vibration device 81. When the vibration device 81 is supported only by the support member 73, the weight of one end portion of the vibration device 81 in the long hand direction and the other end portion are different. It is easy to incline the axial direction of the roller shaft 51, and it is difficult for the user's back to be strongly pressed. However, in this embodiment, the vibrating device 81 is not only borrowed by the support member 73 ', but even if it is larger than the width of the support member 73. The restricting member 76 can also be elastically pushed. For this reason, even if the load on one end and the other end in the long-hand direction of the vibrating device 81 is deviated, the vibrating device 81 is difficult to incline to the axial direction of the roller shaft 51, so it is strongly pressed to the user's On the back, you can improve the massage effect. A pair of winding portions 7 6 a formed at both ends of the above-mentioned restricting member 76 is positioned outside the pair of inner massage rollers 68. For this reason, even if the winding portion 76a is rotatably mounted on the roller shaft 51, the movement along the axial direction of the roller shaft 51 is restricted by the above-mentioned inner massage roller 68, so the restricting member 76 moves in the axial direction of the roller shaft 51 The mounting state of the vibration device 81 does not cause instability. In the implementation form described above, one end of the support member 73 is engaged with one of the pair of support shafts 58 of the roller unit 21, but even if it is engaged with another paper size, the Chinese national standard (0 ^ 5) is applied.

Further, the structure in which the support member 73 is engaged with the roller unit 21 is formed by the support shaft 58 forming an engagement hole. 74. Conversely, even if one end of the supporting member 73 is wound around the supporting shaft 58 thereof. < Effect of hair bun > According to the present invention, a support member and a restriction member formed and formed by a wire having a spring action are mounted on a roller shaft, and a vibration device is mounted on a mounting portion forming the support member and the restriction member. . Therefore, even if the user's weight is biased to the vibration device, the above-mentioned restricting member can elastically deform and absorb its weight bias. Because the vibration of the vibration device does not restrict the movement in the vertical direction, the vibration of the vibration device can be used. Prevents the entire roller unit from vibrating with the roller shaft. In addition, since the vibration device is connected to the supporting member and the restricting member, by virtue of the spring action of the supporting member and the restricting member, the vibrating device can be strongly pushed to the user and the massage effect can be improved. <Brief Description of Drawings> Fig. 1 is a plan view showing a massage device in which a part of an outer package is removed according to an embodiment of the present invention.
