Abstract

PROBLEM TO BE SOLVED: To improve attaching and detaching operability and to elastically and flexibly attach a band. SOLUTION: Hollow hem members 8 of soft materials having cylindrical hollow parts 11 are attached to both side end parts parallel with the lengthwise direction of a band member 7 in the shape of band composed of a cloth member and inside the hollow part 11 of this hollow hem member 8, a shape memory alloy wire 9 having elasticity shape-stored into loop is inserted. Thus, the band member 7 in the shape of band is freely bent into loop by the restitutive force of the shape memory alloy wire 9 shape-stored into loop. Accordingly, when the band is attached while being extended against the elastic force of the shape memory alloy wire 9 at the time of attaching to and detaching from the arm, the band is elastically attached by the restitutive force of the shape memory alloy wire 9. Thus, at the time of attaching and detaching, attaching and detaching operability is improved because the shape and attaching state of the band member 7 is stabilized and the band can be flexibly attached while being fit by the elastic force of the shape memory alloy wire 9 after attaching.
