Claims

[Scope of Claim for Utility Model Registration] 1. Attachment of a buckle of a shoulder belt having a shaft rod for fitting and a buckle having a protruding boss portion with a shaft hole through which the shaft rod of this buckle is inserted. the shaft rod has a flange-shaped head that abuts on the circumferential surface of the shaft hole on the upper surface of the boss, and the free end portion abuts on the circumferential surface of the shaft hole on the lower surface of the boss. A backpack buckle, characterized in that an engaging protrusion is provided, and the shaft hole has an insertion groove for the engaging protrusion extending between the upper and lower opening surfaces. 2. An engaging protrusion is provided on the lower surface of the brim-shaped head of the shaft rod, and a step-like protrusion having an upright engaging surface with which the engaging protrusion engages is provided on the circumferential surface of the shaft hole on the upper surface of the boss. 2. The backpack buckle according to claim 1, further comprising a chevron-shaped protrusion formed of a gentle slope and a steep slope, which allow the engaging protrusion to cross over a mountain, and are provided at intervals in the circumferential direction.
