Slip anchor for seat belt device

A slip anchor for a seat belt device adapted to be attached to a vehicle for guiding a webbing, comprising:

• a fixing plate to be attached to the vehicle and having a back surface,
• a guide member including an upper section fixed to the fixing plate, a lower section situated parallel to the upper section, and two side sections connecting the upper and lower sections at lateral sides thereof to thereby form a guide hole between the upper and lower sections, said lower section being located parallel to and at a predetermined distance away from a plane extending through the back surface of the fixing plate and including a rear surface facing said plane and having an upper end, a lower surface facing in a direction away from the upper section and having a front end, a curved upper surface extending from the upper end of the rear surface to the front end of the lower surface so that the webbing extending along the rear surface changes a direction along the curved upper surface to smoothly guide the webbing, and a curved bottom surface extending between the rear surface and the lower surface so that the lower section has an elongated curved shape in cross section perpendicular to said plane, and
• a resin coating coated over the lower section of the guide member.
