A through anchor includes: a through anchor body that includes a through hole, through which the webbing belt passes, and a support, which is molded using a metal mold and forms part of an inner peripheral surface of the through hole, with a parting line produced during molding being formed on or near the support in the inner periphery of the through hole; and a low-friction member that passes through the through hole and is adhered onto the support, the low-friction member including modified portions and first and second ends in the direction in which the low-friction member passes through the through hole. By aligning the modified portions with the parting line when the low-friction member is passed through the through hole and adhered to the support, the length of the low-friction member at either side of the parting line is proportionally the same.
