PROBLEM TO BE SOLVED: To provide a vehicular shutter in which problems of engine burning-in, heat deterioration, etc. due to flaps with blocked power transmission being held at closing postures can be prevented with a simple structure.SOLUTION: A vehicular shutter 10 which can open and close an outer air introduction passage 8 for introducing the outer air into an engine room comprises: flaps 13 which can open and close the outer air introduction passage 8 by rotating around shaft centers traversing the outer air introduction passage 8; and drive means which drives the flaps to open and close. The position of the center of gravity G of each flap 13 is set so that operation force to the opening posture acts on the flap 13 due to gravity. Wind pressure receiving areas at both sides of the rotation center of each flap 13 are set so that operation force to the opening posture acts on the flap 13 due to wind pressure of the outer air introduced into the engine room through the outer air introduction passage 8. |
