PROBLEM TO BE SOLVED: To improve a soundproof function working between an engine room and a passenger compartment while inhibiting the deterioration of the production efficiency of a dash silencer.SOLUTION: In a vehicle 10, a cowl silencer 60 and a pillar silencer 54 which are formed by members different from a dash silencer 50 and the dash silencer 50 insulate a passenger compartment from sounds from an engine room. In particular, the cowl silencer 60 and the pillar silencer 54 achieve sound insulation between a front pillar 30 and a cowl panel. The structure improves sound insulation effect between the front pillar 30 and the cowl panel, and thus it is not necessary to extend the dash silencer 50 to an area between the front pillar 30 and the cowl panel. Accordingly, addition of a molding process, a trimming process, etc. for the dash silencer 50 is inhibited. Therefore, the structure improves a sound insulation function working between the engine room and the passenger compartment while inhibiting the deterioration of the production efficiency of the dash silencer 50. |
