The band-shaped portion 10 is provided so as to extend from the lower leg portion through the knee 36 to the thigh portion and to be able to apply a contact force to the flexor muscle group that contributes to the bending of the knee 36.

  According to this configuration, since the band-shaped portion 10 can apply a compressive force to the flexor muscle group that contributes to the bending of the knee 36, the extensor muscle group of the leg 30 can be relaxed. As a result, the movement of the knee 36 becomes smooth, and fatigue around the knee 36 is relieved.

  The band-shaped portion 10 extends in the extension direction of the leg 30 from the calf to the thigh flexor muscle group through the space between the calf 36b and the anterior-posterior boundary of the leg 30 at a position where a contact force is applied to the flexor thigh muscle group and the flexor thigh muscle group. The first and second strip-shaped portions 14 and 16 may be included. The first and second belt-shaped portions 14 and 16 may be separated from each other with the popliteal cavity 36j interposed therebetween, and may approach each other as approaching the toes of the foot, and may be connected at the left and right central portions of the calf. In this case, by including the first and second belt-shaped portions 14 and 16, a compressive force can be applied to the flexor leg muscles and the flexor femoral muscle group, so that the extensor group corresponding to these flexor muscles can be relaxed.

  The band-shaped portion 10 may include third and fourth band-shaped portions 12 and 18. The third band-shaped portion 12 may extend in the extending direction of the leg 30 across the anterior-posterior boundary of the leg 30 from the calf to the position beyond the knee 36 at a position where a contact force is applied to the inner part of the soleus muscle. The fourth band-shaped portion 18 may extend in the extending direction of the leg 30 across the anterior-posterior boundary of the leg 30 from the calf to the position beyond the knee 36 at a position where a contact force is applied to the outer part of the soleus muscle. In this case, since the compressive force can be directly applied to the inner side portion and the outer side portion of the soleus muscle, the extensor group corresponding to these flexor muscles can be relaxed.

  The third strip-shaped portion 12 may be separated from the first strip-shaped portion 14 and extend substantially parallel to the first strip-shaped portion 14, or may be shorter than the first strip-shaped portion 14. In this case, if the third strip 12 is too long, the knee 36 is difficult to bend, but since the knee 36 is not too long, the knee 36 is easy to bend.

  The fourth strip-shaped portion 18 may be separated from the second strip-shaped portion 16 and extend substantially parallel to the second strip-shaped portion 16, or may be shorter than the second strip-shaped portion 16. In this case, if the fourth strip 18 is too long, the knee 36 becomes difficult to bend, but since the knee 36 is not too long, the knee 36 is easy to bend.

  The third and fourth belt-shaped portions 12 and 18 may be extended while avoiding the kneecap 36h. In this case, it is possible to suppress a decrease in the compressive force of the third and fourth belt-shaped portions 12 and 18 near the knee 36. Further, when the third and fourth belt-shaped portions 12 and 18 pass through the kneecap 36h, the kneecap 36h feels uncomfortable when the knee 36 is flexed, but the kneecap 36h does not pass, so the discomfort can be alleviated.
