PROBLEM TO BE SOLVED: To provide a valve capable of suppressing collision noise due to opening/closing of a valve body without providing another member to the valve body or the rotational shaft of the valve body.SOLUTION: A valve 10 has a contact part 14 that contacts to a valve body 12 to regulate rotation of the valve body 12 when the valve body 12 is switched from a first state to a second state. The contact part 14 is formed into a projected or truncated shape by being welded to the inner wall of a case 11. The contact part 14 contacts only to a region near a valve rod 13 to be a rotational shaft in the valve body 12, and does not contact to a region far away from the valve rod 13 with respect to the region near the valve rod 13. |
