Claims

[Scope of utility model registration request]

In a bolt connection part with a detent, the bolt is inserted into the flange from a detent washer brought into contact with the flange surface, and the end of the detent washer is bent to prevent the bolt from turning. The flange side structure is formed by forming a small recess or protrusion in a portion of the flange surface that is located outside the outer periphery of a box wrench that operates the bolt.
