To provide a vehicle body joining structure stably enabling the relative movement of a cabin part to a deck frame even in an offset collision.
In a non-collision side connection member 100, a fragile part 110 having a bending strength set higher around the lateral axis of a vehicle than around the longitudinal axis of the vehicle is formed between a cabin side mounting part 110 and a frame side mounting part 102. A load in the lateral direction of the vehicle is applied to the connection member 100 by using the behavior of the rotation of the deck frame 10. Consequently, since the timing of the breakage of the connection member 100 on the non-collision side and the timing of the breakage thereof on the collision side are made close to each other, the cabin part 20 can be stably moved relative to the deck frame 10.
