In addition, since the pressing protrusions 32b and 32c are positioned at the positions desired by the user, a good massage effect can be obtained.

In the second embodiment, the lateral movements of the respective moving plates 137 are made independently of each other, but this is done by using a rack mechanism, for example , to move the moving plates 137 at the same time to approach / separate at the same time. Alternatively, both moving plates 137 can be moved simultaneously . However, when both moving plates 137 are moved separately as in this embodiment, there is an advantage that the desired position can be finely adjusted even when the desired position is not symmetrical due to the body shape or the like. Also in the second embodiment, each pressing plate 32 is provided with two pressing protrusions 32b and 32c, but one or two or more are provided as in the first embodiment. Also, the shape may be an arbitrary shape.
