A variable vent mechanism has an air bag having a vent hole, a flap attached to the air bag at a first fix portion and covering the vent hole, a strap extending from a connection end of the flap, fixed to an attachment portion at a second fix portion, and fixing the flap in a closed position where the vent hole is closed, and a device which brings the strap into a free state. A relationship L3/L4 between a maximum length L3 between the first fix portion and the connection end in a first direction connecting the first and second fix portions, and a maximum length L4 of the first fix portion in a second direction orthogonal to the first direction satisfies 0.5≤L3/L4≤3.0. A length of the flap in the second direction is shorter on the connection end side than on the first fix portion side.
