Since the pole member rotates in the stretch device disclosed in Patent Literature 1, the pole member needs to have considerable rigidity and is hard. Therefore, when the pole member presses against the user's body, the user feels pain.
In addition, in the column of [Background Art] in Patent Document 1, a stretch device using an elastic columnar material is disclosed, but a stretch device using an elastic material is in use. Temporarily deforms and the feeling of hitting the body changes.
In other words, stretching is performed by stretching the muscles and muscles or holding the relaxed state for a certain period of time, and changing the stretched muscles and muscles. For example, stretch the whole body by changing the stretched part from the muscles of the back to the muscles of the side.
For example, the back is pressed against the pole member for a relatively long time such as one minute. Then repeat this several times before moving on to the next muscle stretch. For example, the side is pressed against the pole member, and this state is maintained for a certain time.

  As mentioned above, if you stretch a part of your body first and then stretch other parts, when you stretch later, the pole member of the stretch device will remain deformed when stretched first.

  As shown in FIG. 2, the stretch device 1 according to the present embodiment includes a binding block 6 inserted into a bag body 2, and the binding block 6 is built in a slightly compressed state.

  Since the stretch device 1 of the present embodiment has a triangular prism shape as shown in FIG. 1, it has three corners A, B, and C. In each corner A, B, C there is a cylinder 5.

  In the above-described embodiment, the six cylindrical bodies 5 are bound and inserted into the bag body 2. However, the number of the cylindrical bodies 5 is not limited to six. For example, the stretch device shown in FIG. 30 may be obtained by binding three cylindrical bodies 5 together.

  The usage method of the stretch devices 1 and 30 is arbitrary. For example, as shown in FIG. 8, the person may lie on his back on the stretching devices 1 and 30 and press the corner A against the muscles around the spine. Alternatively, the whole body force may be removed with the angle A applied to the spine muscles, and the muscles around the spine may be relaxed and stretched.

Further, as shown in FIGS. 9 and 10, the stretch devices 1 and 30 may be arranged so as to intersect with the user, and the corner A may be applied to the hip bone or the rib.
Furthermore, as shown in FIGS. 11 and 12, the corner A of the stretch device 1 or 30 may be applied near the elbow.

In addition, if the surface of the stretch device 1, 30 is recessed during use, and it becomes difficult to return to the original shape even if the force is removed, the stretch device 1, 30 is rotated and the corner B or C is faced upward. Or press the body against the corner C.
While using the corner B or the corner C, the recessed portion of the previous corner A swells and returns to the original shape. Therefore, the corner A can be used later.
