PROBLEM TO BE SOLVED: To suppress an influence to the rigidity of a cab, and to effectively reduce noise.SOLUTION: A rear pillar part 11 has a pillar internal space 15 therein. Internal openings 16 are formed at lower ends of internal plate parts 8b of rear pillars 8, and external openings 17 are formed at upper ends of outer ends 5a of a back panel 5. A back panel trim 24 is arranged in a position separated to a front part from a back panel part 12, and defines a cab rear space 19 between the back panel part 12 and itself. A back panel trim 24 has a plurality of slits 25 at a lower end of a center part in a vehicle width direction. An indoor space 26 communicates with a vehicle outside space 18 via the slits 25 of the back panel trim 24, the cab rear space 19, the internal openings 16 of the internal plate parts 8b of the left and right rear pillars 8, the pillar internal space 15, and the external openings 17 of the left and right outer ends 5a of the back panel 5.SELECTED DRAWING: Figure 3 【課題】キャブの強度に対する影響を抑え、且つ騒音を効果的に低減する。【解決手段】リヤピラー部１１は、内部にピラー内部空間１５を有する。リヤピラー８の内板部８ｂの下端部には、内部開口１６が形成され、バックパネル５の外端部５ａの上端部には、外部開口１７が形成される。バックパネルトリム２４は、バックパネル部１２から前方へ離間した位置に配置され、バックパネル部１２との間にキャブ後部空間１９を区画する。バックパネルトリム２４は、車幅方向中央部の下端部に、複数のスリット２５を有する。室内空間２６は、バックパネルトリム２４のスリット２５、キャブ後部空間１９、左右のリヤピラー８の内板部８ｂの内部開口１６、ピラー内部空間１５、及びバックパネル５の左右の外端部５ａの外部開口１７を介して車両外部空間１８と連通する。【選択図】図３
