In a through anchor, it enables a piece to be moved to an attachment position of the piece in a metal core by moving the piece toward a vehicle front lower side in a state in which a lower end portion of a guide portion of a guide groove of the piece is abutted with a guide projection formed at a metal core lower portion of the metal core.

Anchor for seatbelt device

In a through anchor, a thinned portion is formed at a metal core lower portion of a metal core. This thereby enables an increase in body size of the through anchor to be prevented or suppressed even when a mold portion is made thick at the portion of the metal core where the thinned portion is formed.

In the present pretensioner, press contact portions are formed further to a side of an open end of a packing housing section than central portions of opposing faces along a depth direction of the packing housing section. Accordingly, when a packing is being fitted into the packing housing section, no great resistance is imparted to a curved face side of the packing from a press contact wall of a housing section body and the opposing face, and the packing is fitted comparatively smoothly therein. Consequently, even when fitting the packing into the packing housing section, a packing main body is largely resilient-deformed, such that a large collapse in a through hole can be prevented, and the sealing ability of the seal due to deformation of the packing main body can be effectively enhanced.
