Sound insulation structure for vehicle

A sound insulation structure for a vehicle, in which a sound insulator is provided in a void space surrounded by:

• a front fender panel;
• a cowl side member disposed on a vehicle inward side with respect to the front fender panel to extend in a vehicle front-rear direction;
• and a mud guard disposed just below the front fender panel and the cowl side member to form a wheel housing, wherein the sound insulator is formed using a single-piece elastically-deformable material, and fixed in the void space by means of its own compressive reaction force, the sound insulator comprising:
• a vertical wall portion formed on a surface thereof on the side of the cowl side member, the vertical wall portion having a vehicle front-rear directional length which is set to a value less than a vehicle front-rear directional length of the sound insulator;
• and
• a slit formed in the vertical wall portion capable of clamping an elongated line component laid to extend in the vehicle front-rear direction and pass through the void space,
• and wherein the sound insulation structure comprises a guiding cavity for guiding the elongated line component insertably toward the slit, the guiding cavity being formed on the side of an inlet of the slit by a V-shaped inclined surface provided on the vertical wall portion,
• and wherein:
• the guiding cavity is formed to be capable of housing an additional elongated line component laid to extend in the vehicle front-rear direction and pass through the void space;
• and
• the slit is formed to extend from the surface of the sound insulator on the side of the cowl side member toward the front fender panel, in a vehicle width direction.
