RESIN CASTING STRUCTURE OF BOLT OR NUT

PROBLEM TO BE SOLVED: To prevent co-rotation of a bolt or a nut, even if high torque is applied to the bolt or the nut embedded in the resin molding, when installing the resin molding, and thereby to install a resin molding without severely managing torque. SOLUTION: A resin casting structure of a b...

Zusammenfassung:	PROBLEM TO BE SOLVED: To prevent co-rotation of a bolt or a nut, even if high torque is applied to the bolt or the nut embedded in the resin molding, when installing the resin molding, and thereby to install a resin molding without severely managing torque. SOLUTION: A resin casting structure of a bolt or a nut is molded by casting a spanner hooking part of the bolt or the nut in resin when forming the resin molding. Hard resin molding bodies 14 and 24 of diametrically expanding an outer diameter of the spanner hooking part by a hard resin 13, are constituted by casting the spanner hooking parts 22a and 12a of the bolt 22 or the nut 12 in the resin 13 harder than the resin molding 7a, and the resin molding 7a is molded by casting the hard resin molding bodies in the resin. At least one of a recessed part 13c or a projection part 13d is desirably formed on an interface surface with the resin molding 7a of the hard resin molding bodies 14 and 24, or on an interface surface with the hard resin molding bodies 14 and 24 of the bolt 22 or the nut 12.
