The body fixing part 95 extends from the top of the base 911 to the body first fixing band 951, and extends from the bottom of the base 911 and selectively with the body first fixing band 951. The body may include a second fixing band 955 to be connected.

The body first fixing band 951 may be provided to have a wider left and right width than the body second fixing band 955, and the body first fixing band 951 may include the body second fixing band 955. There may be provided a plurality of band insertion holes (951a) to be selectively inserted.

In addition, one surface of the second fixing band 955 may be provided with a body first attaching member 956 and a body second attaching member 957 selectively coupled with the body first attaching member 956. The first body attaching member 956 and the second body attaching member 957 may be formed of a velcro that can be coupled to each other.

Accordingly, when the body second fixing band 955 is inserted into the band insertion hole 951a and the body first attaching member 956 and the body second attaching member 957 are coupled to each other, the arm is fixed to the user's arm. The body band 90 may be firmly coupled.

On the other hand, the body band 90 may be coupled to other parts such as the user's waist as well as the arm.

Referring to Figure 9, it can be seen another embodiment in which the body band 90 is worn on the waist of the user.

Basically, as described above, when the body band 90 is fixed to the waist of the user, the body first fixing band 951 and the body second fixing band 955 are respectively left and right sides of the base 911. It would be desirable to be provided to extend at the end.

Even if the effects are not described in the present specification, the present invention may additionally have different effects of the above-described elements, and may have new effects different from those of the prior art according to the organic coupling relationship between the above-mentioned elements. Of course.

In addition, the embodiments shown in the drawings may be embodied in other forms, and should be regarded as belonging to the scope of the present invention if it is carried out including the configuration claimed in the claims of the present invention or within the equivalent scope. something to do.
