Abstract

PURPOSE: To provide straps capable of being simply adjusted to an optional length, generating no obstructive portion, and capable of being compactly stored by providing a means capable of winding the straps and keeping its state on a shoulder pad. CONSTITUTION: A winding tube 6p of straps 2, 2' erected at the center of the inner face of a winding disk 6 is idly inserted into the outer diameter of a tube shaft 3p erected on a shoulder pad bottom plate 3, and it is pressed upward by a spring 7 in the tube shaft 3p. A clutch plate 5 couples a clutch pawl 5t with a clutch gear to press the flange section 6f of the winding disk 6. When the winding disk 6 is thrust against the excitation of the spring 7, the clutch gear of the flange section 6f is released from the coupling of the clutch pawl 5t of the clutch plate 5 and turned CW, and the straps 2, 2' are wound on the winding tube 6p. When the thrust of the winding disk 6 is released, the winding disk 6 is returned by the spring 7, the clutch pawl 5t of the clutch plate 5 is coupled with the clutch gear of the flange section 6f, and the wound state is maintained. When the center section of the winding disk 6 is pushed by a finger to release the coupling between the clutch gear and the clutch pawl 5t, the straps 2, 2' are drawn out.
