Claim Text:
1. A belt member comprising: a strip member having an elongate shape; a fastener disposed along a longitudinal direction of the strip member; and an opening-closing device that opens or closes the fastener, wherein for reducing a contact pressure of the belt member per unit area, the fastener is opened by the opening-closing device to unfold the belt member into a form of a wide strip so that a width of the belt member is increased, the fastener extending less than an entire length of the strip member in the longitudinal direction of the strip member such that only a portion of the belt member is configured to unfold into the wide strip form, and when the fastener is closed by the opening-closing device, the belt member takes a form of a narrow tube so that the width of the belt member is reduced, wherein the opening-closing device is separate from the strip member and engages the fastener to open and close the fastener.
