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, the main body portion having an other region; 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; a second support portion that supports an end portion provided at an opposite side from the first loopback end portion on the other region of the main body portion; a lever portion configured to cause a free state and a lock state to be switchable from each other, where the one region is provided opposite to the first support portion across the main body portion and is slidable relative to the first support portion in the free state and is not slidable in the lock state,   wherein the locking mechanism holds the one region between the first support portion and the lever portion to realize the lock state.   
     
     
         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 a 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 around a 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 a 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 around a 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 5 , 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.   
     
     
         7 . The strap portion according to  claim 1 , wherein the lever portion is configured to adjust a length of the main body portion in the one region in a longitudinal direction of the main body portion during the free state.
