Abstract: A method for producing a belt molding includes: inserting an insertion portion of an end cap into a molding body such that the insertion portion faces a facing portion of the molding body while the facing portion is positioned on a vehicle interior side relative to the insertion portion; and forming a protruding portion in the molding body. The protruding portion protrudes on a vehicle exterior side relative to a vehicle interior side surface of the insertion portion. The protruding portion is formed by deforming a portion of the facing portion which is closer to the lid portion of the end cap relative to the catch surface.

Abstract: A glass run channel assembly of the invention includes a connecting glass run channel that is connected to first and second glass run channels, respectively. A base bottom portion of the connecting glass run channel is formed with an insertion hole to which an engaging member can be attached, and lateral inner walls that configure the periphery of the insertion hole are formed with locking portions that are locked to a trunk portion when the engaging member is inserted into the insertion hole.
