As is apparent from the above description, according to the guide anchor for the seat belt of the present invention, the guide piece is temporarily fixed to the guide plate to prevent the guide piece from being displaced or falling off the guide plate. It is difficult to generate the guide plate when the guide piece is temporarily attached to the guide plate by an automatic machine, when the mold is closed by an automatic machine, or when the guide piece and the guide plate are transported by the automatic machine. Position of the guide piece with respect to the guide plate and the guide piece can be prevented from falling off the guide plate. Thereby, breakage of the mold or the guide piece can be prevented.

Further, the guide piece is temporarily fixed to the guide plate by press-fitting the guide piece using elastic deformation of the guide piece by the wedge effect of the inclined portion or elastic deformation of the guide piece by the locking projection. Since the guide piece is simply pressed into the guide plate, the guide piece can be easily and reliably temporarily fixed to the guide plate by an automatic machine or the like. In this way, it is possible to easily prevent the guide piece from being temporarily fixed and prevent the guide piece from being displaced or falling off. Therefore, the primary fixation and molding of the guide piece to the guide plate can be performed more quickly and more accurately, and mass production of the seat belt guide anchor can be performed with high quality. .
