Abstract:
1. A flap door mechanism, comprising: a door member pivoted to a casing and comprising a pushing structure; a resilient member installed on the door member and for driving the door member to rotate in a first direction, the resilient member comprising a first end and a second end; and a spring arm member connected to the casing, the spring arm member comprising an abutting end for abutting against the first end, the second end of the resilient member abutting against the door member, the resilient member driving the first end to push the abutting end and the pushing structure pushing the spring arm member for bending the spring arm member to make the abutting end expand out of the casing when the door member rotates in a second direction opposite to the first direction, so as to reduce deformation between the first end and the second end of the resilient member.
