PROBLEM TO BE SOLVED: To provide a vent cap that can correct a mounting position by simple operation according to the deviation width of a sleeve, and at the same time has superior design by finely adjusting height and distance for mounting the bent cap. SOLUTION: A vent cap is composed of a cylindrical grill 1 where a lattice 12a for preventing a small animal from entering is formed on a front surface, and a hooking part is formed at an edge part on a rear surface, a fitting surface 21 that can be fitted onto the rear surface of the grill, and an insertion member 2 that is formed a position deviating from the center of the fitting surface and has a cylinder part 22 penetrating through the fitting surface. When the insertion member 2 is mounted to the grill 1, the insertion member is rotated for positioning at a specific position while the edge part of the fitting surface 21 of the insertion member is loosely fitted to a hooking part 11a of the grill. When the insertion member 2 is positioned, the hooking part 11a of the grill 1 is fitted to the edge part of the fitting surface 21 of the insertion member, and the insertion member is sealed to the grill. |
