Claims

[Scope of utility model registration request]

Overlap each end of the front inner channel and rear inner channel, which have a U-shaped cross section, and
The ends of one inner channel and the U-shaped outer surface of the other inner channel are linearly connected by welding, and the U-shaped side surfaces of both inner channels are connected to the U-shaped side surfaces of the frame side rails, which have a U-shaped cross section. In an inner channel joint structure formed by overlapping and welding the side ends of the frame side rails and the U-shaped side surfaces of both the inner channels, a side surface portion extending in the direction of the other inner channel, or an outer surface portion welded to the outer surface of the other inner channel at the end of the one inner channel is formed with a notch in a direction away from the other inner channel. An inner channel joint structure characterized by:
