## Abstract

A grille shutter device includes: a first bumper reinforcement extending in a vehicle width direction; and a shutter mechanism that is provided with a plurality of support members extending from the first bumper reinforcement in a direction intersecting with the vehicle width direction, is supported by the plurality of support members, and regulates a flow rate of air which flows into an engine room from a grille.

## Claims

### Claim 1

A grille shutter device comprising:
a first bumper reinforcement extending in a vehicle width direction; and
a shutter mechanism that is provided with a plurality of support members extending from the first bumper reinforcement in a direction intersecting with the vehicle width direction, is supported by the plurality of support members, and regulates a flow rate of air which flows into an engine room from a grille, wherein
the shutter mechanism includes a movable fin that is rotatably supported by the plurality of support members,
the movable fin has a distal portion provided with a seal member that is elastically deformable, and
a distance from a rotary shaft of the movable fin to a distal end of the seal member attached to the movable fin is set to be longer than a distance from the rotary shaft of the movable fin to the first bumper reinforcement, and a distance from the rotary shaft of the movable fin to the distal portion of the movable fin not including the seal member is set to be shorter than a distance from the rotary shaft of the movable fin to the first bumper reinforcement.

### Claim 2

A grille shutter device comprising:
a first bumper reinforcement extending in a vehicle width direction; and
a shutter mechanism that is provided with a plurality of support members extending from the first bumper reinforcement in a direction intersecting with the vehicle width direction, is supported by the plurality of support members, and regulates a flow rate of air which flows into an engine room from a grille, wherein
an end of the plurality of support members on a side opposite to the first bumper reinforcement is connected to a second bumper reinforcement extending in the vehicle width direction,
the shutter mechanism includes a movable fin that is rotatably supported by the plurality of support members,
the movable fin has a distal portion provided with a seal member that is elastically deformable, and
a distance from a rotary shaft of the movable fin to a distal end of the seal member attached to the movable fin is set to be longer than a distance from the rotary shaft of the movable fin to the first bumper reinforcement, and a distance from the rotary shaft of the movable fin to the distal portion of the movable fin not including the seal member is set to be shorter than a distance from the rotary shaft of the movable fin to the first bumper reinforcement.

### Claim 3

A grille shutter device comprising:
a first bumper reinforcement extending in a vehicle width direction; and
a shutter mechanism that is provided with a plurality of support members extending from the first bumper reinforcement in a direction intersecting with the vehicle width direction, is supported by the plurality of support members, and regulates a flow rate of air which flows into an engine room from a grille, wherein
an end of the support member on a side opposite to the first bumper reinforcement is connected to an absorber,
the shutter mechanism includes a movable fin that is rotatably supported by the plurality of support members,
the movable fin has a distal portion provided with a seal member that is elastically deformable, and
a distance from a rotary shaft of the movable fin to a distal end of the seal member attached to the movable fin is set to be longer than a distance from the rotary shaft of the movable fin to the first bumper reinforcement, and a distance from the rotary shaft of the movable fin to the distal portion of the movable fin not including the seal member is set to be shorter than a distance from the rotary shaft of the movable fin to the first bumper reinforcement.
