Abstract:
1. A through anchor comprising: a main body portion that is manufactured from metal, and at which a through hole, which is for forming an insertion hole through which a webbing that restrains an occupant is inserted, is formed; a piece that is assembled to the main body portion so as to cover a portion of an inner peripheral edge portion of the through hole, and whose face configures a slide contact portion that makes sliding contact with the webbing; a covering portion that is formed by molding integrally with the piece and the main body portion with the slide contact portion being in an exposed state, that covers another portion of the inner peripheral edge portion of the through hole, and that configures an inner peripheral portion of the insertion hole together with the piece; a groove portion that is formed at a boundary portion between the piece and the covering portion; a piece side inclined face that configures a side face of the groove portion at a piece side, with an angle formed between the piece side inclined face and the slide contact portion being set as an obtuse angle as viewed in a cross-section orthogonal to the groove portion, and a covering portion side inclined face that configures a side face of the groove portion at a covering portion side, with an angle formed between the covering portion side inclined face and a face of the covering portion being set as an obtuse angle as viewed in the cross-section orthogonal to the groove portion, wherein, as viewed in a cross-section orthogonal to the groove portion, a length of the piece side inclined face is longer than a length of the covering portion side inclined face, and an angle α2 formed between the piece side inclined face and the slide contact portion is larger than an angle α3 formed between the covering portion side inclined face and the face of the covering portion, the face being adjacent to the covering portion side inclined face.
