To inhibit deformation of a floor panel caused by a load from a seat belt.SOLUTION: A first plate part 27 of a rear mount rail 16 is fixed to a rear end 14a of a floor panel 14 and erected from the rear end 14a of the floor panel 14 along a vehicle width direction. A reinforcement 18 is fixed to a rear surface of the first plate part 27 of the rear mount rail 16, extends in the vehicle width direction, and reinforces the rear mount rail 16 at a rear end lower part of a cab 2. A reinforcement member 19a is a member which reinforces the floor panel 14 and has: a front fixture part fixed to a bolt fixture part of the floor panel 14; and a rear fixture part 36 fixed to the reinforcement 18. The reinforcement member 19a extends in an anteroposterior direction along a lower surface 14b of the floor panel 14 and a lower surface 18b of the reinforcement 18 and connects the bolt fixture part of the floor panel 14 with the reinforcement 18.SELECTED DRAWING: Figure 4

    【課題】シートベルトからの荷重によるフロアパネルの変形を抑える。【解決手段】リヤマウントレール16の第1板部27は、フロアパネル14の後端部14aに固定されてフロアパネル14の後端部14aから車幅方向に沿って起立する。レインフォース18は、リヤマウントレール16の第1板部27の後面に固定されて車幅方向に延び、キャブ2の後端下部のリヤマウントレール16を補強する。補強部材19aは、フロアパネル14を補強する部材であって、フロアパネル14のボルト固定部に対して固定される前側固定部と、レインフォース18に対して固定される後側固定部36とを有する。補強部材19aは、フロアパネル14の下面14b及びレインフォース18の下面18bに沿って前後方向に延び、フロアパネル14のボルト固定部とレインフォース18とを連結する。【選択図】図4
