The first keyway 44 is provided at an angle of 130 degrees. Therefore, the roller bearing 41 can swing in the front-rear direction within a range of 45 degrees with the first support shaft 38 as a fulcrum.

The roller bearing 41 is provided with a hollow second support shaft 45 as a block support shaft at both ends in the axial direction, which is a direction orthogonal to the first mounting hole 42. A flange 45a is formed at the distal end of the second support shaft 45, and a plurality of slits 45b are formed at predetermined intervals in the circumferential direction along the axial direction and open to the distal end surface. Thus, the distal end of the second support shaft 45 can be elastically deformed in the diameter reducing direction.

A pair of second support shafts 45 of each roller bearing 41
, A block 47 is rotatably mounted by fitting a third mounting hole 48 formed therein.
That is, the inner diameter of the third mounting hole 48 is equal to the second inner diameter.
Smaller than the outer diameter of the flange 45a of the support shaft 45,
The outer diameter of the portion other than the flange 45a is set slightly larger. Therefore, if the distal end of the second support shaft 45 is elastically deformed in the diameter reducing direction, the third mounting hole 48 of the block 47 is fitted therein, and then the reduced diameter state is released. The block 47 is rotatable and its end face is engaged with the flange 45a so that the block 47 cannot be pulled out.

On a pair of opposing side surfaces of each of the blocks 47, the axis is aligned with the roller mounting 41 in a direction orthogonal to the axis of the third mounting hole 48, that is, in a state of being mounted on the roller bearing 41. A pair of roller support shafts 49 protrude in a state perpendicular to the axis. Each roller support shaft 49 has a hollow shape, a flange 49a is provided at the distal end, and a plurality of slits 49 having one end opened at the distal end surface.

As shown in FIG. 4, a second key 51 is formed on the end face of the roller bearing 41 where the second support shaft 45 protrudes in a range of 40 degrees in the circumferential direction. The second key groove 5 with which the second key 51 is engaged is provided on the end face.
2 are formed in a range of 80 degrees in the circumferential direction. Therefore, the block 47 is swingable in a range of 40 degrees in the circumferential direction.

As shown in FIGS. 5 and 6, a massage roller 53 having a plurality of arc-shaped projections 53a (in this embodiment, ten) is rotatably mounted on each roller shaft 49 as described later. Have been. That is, each holder 2
There are 16 massage rollers 5 in each of 1a and 21b.
The massage roller 53 is provided with the roller bearing 41 and the block 47 with respect to the roller support 35.
And a roller shaft 49 for swinging in the front-rear direction and the left-right direction.

The massage roller 53 has a mounting hole 53b having a diameter smaller than that of the flange 49a of the roller shaft 49 and slightly larger than a portion other than the flange 49a.
Accordingly, if the mounting hole 53b of the massage roller 53 is fitted in a state where the tip end of the roller shaft 49 is elastically deformed in the diameter reducing direction, and then the diameter reducing state is released, the massage roller 53 can rotate freely. The flange 49a on the end face
Are engaged and cannot be pulled out.

After the roller bearing 41 is attached to the first support shaft 38, a spring ring (not shown) is attached to the end of the first support shaft 38 so that the roller bearing 41 cannot be pulled out. However, similarly to the block 48 and the massage roller 53, although not shown, the first support shaft 38 may be provided with a slit and a flange so that the first support shaft 38 cannot be pulled out.

As described above, the first support shaft 38 provided at one end of the roller support 35 around the boss 37 and the first support shaft 38 provided at the other end have a width as described above. In the direction by a predetermined dimension S. Thereby, each of the first
The massage rollers 53 which are attached to the support shaft 38 via the roller bearing 41 and the block 47 and are positioned at one end and the other end of the roller support 35 are also shifted by the dimension S.

Here, as shown in FIG. 6, the dimension S is set to a half of the distance P between the pair of massage rollers 53 attached to the pair of roller shafts 49 of one block 47. Therefore, the eight massage rollers 53 located in four rows on one end side of the roller support 35 and the eight massage rollers 53 located in four rows on the other end side are the same as those of the roller support 35. P in the width direction
/ 2 each. That is, when the massage rollers 53 in each row of the roller support 35 are reciprocally driven along the longitudinal direction of the base 1, each row runs at a different position in the width direction of the base 1.

The upper surface and the lower surface of the base 1 are covered with a cover 54 made of stretchable fabric. A tension is applied to the cover 54, whereby the cover 54 comes into pressure contact with the massage roller 53 provided on each of the holders 21a and 21b, thereby restricting the massage roller 53 from swinging freely. This state is shown in FIGS. 10 (a) and 10 (b).

Although not shown in detail, the cover 54 has a two-piece structure of a holding cover made of an elastic cloth for restricting the swing of the massage roller 53 and an exterior cover covering at least the upper surface side of the base 1. It may be. In this case, the holding cover may have a band shape that covers only the holding members 21a and 21b.

The massage roller 53 provided on the roller support 35 is prevented from swinging in the front-rear direction and swinging in the left-right direction by the first and second keyways and keys. Since the swing around the hollow shaft 22 is also regulated by the support shaft 27a provided between the supports 23, the swing of each massage roller 53 need not be regulated by the cover 54.

In the massage device having such a configuration, when receiving a massage, if the user lies on the cover 54, the drive source 12 is operated to activate the belt 15.
