Abstract
A structure for suppressing noise into a vehicle passenger compartment includes: a dash panel that separates a vehicle passenger compartment and a power unit chamber that is disposed at a vehicle front side; an instrument panel that covers the dash panel from a vehicle rear side, and that has a lower wall portion which extends toward a vehicle front side and forms an opening portion with the dash panel; and a sound insulating member that is disposed so as to cover the opening portion or is disposed so as to partition a space portion, which is between the dash panel and the instrument panel, in a vehicle transverse direction.

A structure for suppressing noise into a vehicle passenger compartment, the structure comprising:
- a dash panel that separates the vehicle passenger compartment and a power unit chamber that is disposed at a vehicle front side;
- an instrument panel that covers the dash panel from a vehicle rear side, and that has a lower wall portion which extends toward a vehicle front side and forms an opening portion with the dash panel;
- and
- a sound insulating member that is disposed so as to cover the opening portion or is disposed so as to partition a space portion, which is between the dash panel and the instrument panel, in a vehicle transverse direction, wherein the sound insulating member has:
- a base portion that is mounted to a rear surface of the dash panel, and
- a partitioning portion that extends from the base portion toward the vehicle rear side, that contacts the lower wall portion, and that partitions the space portion into a driver's seat side and a front passenger's seat side.

- a partitioning portion that extends from the base portion toward the vehicle rear side, that contacts the lower wall portion, and that partitions the space portion into a driver's seat side and a front passenger's seat side, wherein:
- the base portion is elastically deformable,
- the sound insulating member has a high-density portion having a density higher than a density of the base portion, and
- the high-density portion is mounted to the base portion from the vehicle rear side further toward a vehicle lower side than the opening portion, wherein
- the sound insulating member has a cover portion that extends from the base portion toward the vehicle rear side, that contacts the lower wall portion, and that covers the opening portion.
