Claims

[Scope of utility model registration request]

In construction machinery, etc., in which rotation of the pin is prevented by stopping a bracket fixed to one end of the pin that connects the first member and the second member via a stopper welded to the supporting member of the pin. In the pin locking structure,
A structure for preventing rotation of a pin, characterized in that a stopper which also serves as a guard and is made up of an enveloping part surrounding the bracket and an opening part that sandwiches the tongue-like part of the bracket is welded to the supporting member of the pin.
