In the tongue plate holder (seatbelt holder) described in Patent Document 1, the mounting portion of the seatbelt holder is fixed to the trim (the inner surface of the vehicle interior), and is positioned at a position separated by a substantially constant holding gap from the mounting portion. A main body is arranged. The main body portion is formed thick so as to provide an insertion hole for inserting the plate portion of the tongue plate. In this way, since the main body portion arranged at a position spaced apart from the inner surface of the passenger compartment is formed to be thick, there is a possibility that the amount of protrusion of the seatbelt holder from the inner inner surface of the passenger compartment to the passenger compartment side becomes large. On the other hand, if the main body is formed thin without providing an insertion hole in the main body, the tongue plate may vibrate when the vehicle vibrates and hit the interior surface of the vehicle, generating contact noise.

Accordingly, an object of the present disclosure is to provide a seatbelt retainer that can hold a tongue plate while suppressing the amount of protrusion from the interior surface portion toward the interior of the vehicle.

In order to solve the above-mentioned problems, a first aspect of the present invention is a seat belt holding device that holds the webbing and the tongue plate of a seat belt having a tongue plate and a webbing formed with locking holes on the vehicle interior surface side. A tool comprising a mounting portion and a holding portion. The attachment portion is attached to the interior surface of the vehicle.
