Abstract

A strap comprising a main body portion formed in a belt shape and provided with a first loopback end portion formed by intermediate portion being looped back; and a locking mechanism provided with a first support portion slidably supports one region of the main body portion viewed from the first loopback end portion, and a second support portion supports an end portion provided at an opposite side from the first loopback end portion on an other region, and the locking mechanism being switchable between a free state and a locked state.

1 . A strap comprising:
 a main body portion formed in a belt shape and provided with a first loopback end portion formed by a length direction intermediate portion being looped back; and   a locking mechanism provided with a first support portion that slidably supports one region of the main body portion viewed from the first loopback end portion, and a second support portion that supports an end portion provided at an opposite side from the first loopback end portion on an other region of the main body portion, and the locking mechanism being switchable between a free state, in which sliding between the one region and the first support portion is enabled, and a locked state, in which the sliding is restricted.   
   
   
       2 . The strap according to  claim 1 , wherein
 the end portion provided at the opposite side from the first loopback end portion on the other region   is supported at the second support portion in a state in which relative movement with respect to the second support portion in the length direction of the main body portion is restricted.   
   
   
       3 . The strap according to  claim 1 , further comprising:
 a hanging portion formed in a belt shape and used by being hung round the body of a user; and   a third support portion that slidably supports the first loopback end portion and is connected to an end portion of the hanging portion, wherein   in the main body portion, an end portion provided at the opposite side from the first loopback end portion on the one region is connected to an attachment object, and   the locking mechanism is provided to be relatively movable with respect to the third support portion along the length direction of the main body portion.   
   
   
       4 . The strap according to  claim 1 , further comprising:
 a hanging portion formed in a belt shape and used by being hung round the body of a user; and   a third support portion that slidably supports the first loopback end portion and is connected to an end portion of the hanging portion, wherein   the second support portion slidably supports a second loopback end portion which is formed by a length direction intermediate portion of the other region of the main body portion being looped back,   in the main body portion, an end portion provided at the opposite side from the first loopback end portion viewed from the second loopback end portion on the other region is supported at the third support portion, and an end portion provided at the opposite side from the first loopback end portion on the one region is connected to an attachment object, and   the locking mechanism is provided to be relatively movable with respect to the third support portion along the length direction of the main body portion.   
   
   
       5 . The strap according to  claim 4 , wherein
 the second support portion is provided with a first roller that is turnable about an axis parallel with a width direction of the main body portion, and   the second loopback end portion of the main body portion is wound on an outer peripheral surface of the first roller.   
   
   
       6 . The strap according to  claim 3 , wherein
 the third support portion is provided with a second roller that is turnable about an axis parallel with a width direction of the main body portion, and   the first loopback end portion of the main body portion is wound on an outer peripheral surface of the second roller.
