PROBLEM TO BE SOLVED: To provide a strap fastener that makes a loop with a desired dimension, superior appearance, and high safety and that has a smaller number of components thereby having suppressed cost. SOLUTION: The strap fastener includes a connecting component 3 attached to one end of a strap 2 and a length adjusting component 4 attached to the other end of the strap 2. In the length adjusting component 4, a holder portion 15 is formed that slidably holds the middle of the strap 2. In the connecting component 3, a loop-shaped strap-through portion 39 is formed that passes an intermediate part between the other end of the strap 2 attached to the length adjusting component 4 and the middle of the strap held by the holder portion 15. The strap-through portion 39 is released so that the strap 2 put through the strap-through portion 39 may come out of it when an external force is applied thereto. COPYRIGHT: (C)2011,JPO&INPIT |
