Abstract:
1. A hinge structure for mounting a swingable member which is swingable relative to a body member, comprising: a first knuckle formed on said swingable member; a second knuckle formed on said body member so as to be coaxial with said first knuckle; and a pivot pin extending through said first knuckle and said second knuckle to join said first knuckle and said second knuckle to each other; wherein said pivot pin is provided with at least one radial projection formed at one end thereof to extend radially outwards in a first direction, a width of said radial projection in a second direction, perpendicular to said first direction, being smaller than a diameter of said pivot pin; wherein one of said first knuckle and said second knuckle is provided with at least one groove which is formed in one end surface of said one of said first knuckle and said second knuckle, wherein said radial projection is fitted into said groove to prevent said pivot pin from rotating relative to said one of said first knuckle and said second knuckle, said radial projection being received into said groove in such a manner that a top surface of said radial projection does not extend beyond said one end surface of said one of said first knuckle and said second knuckle, and wherein said radial projection extends within said groove to an outer periphery of said one of said first knuckle and said second knuckle; wherein said at least one groove comprises a plurality of grooves arranged at equi-angular intervals about an axis of said pivot pin; and wherein said at least one radial projection comprises a corresponding plurality of radial projections arranged at equi-angular intervals about said axis of said pivot pin to be fitted into said plurality of grooves, respectively.
