PROBLEM TO BE SOLVED: To provide a fan unit which achieves an easier mounting work of a bearing at a low cost and with a simple structure. SOLUTION: A hole 38 and a groove 39 on the side opposite to the hole 38 are provided in an internally semi-cylindrical bearing base 14 which is integrally formed with a casing 11 to support almost the semi-circumference of a bearing 19. An internally semicircular bearing presser 25 for supporting almost a semi-circumference of the bearing 19 is provided with a protrusion part 40 to be inserted into the hole 38 and a protrusion piece 41 to be retained in the groove 39 facing the bearing base 14. The protrusion part 40 of the bearing base presser 25 is inserted into the hole 38 of the bearing base 14 and the bearing presser 25 is turned to fit the protrusion piece 41 of the bearing presser 25 into the groove 39 of the bearing base 14. Thus, the bearing 19 is supported by the bearing base 14 and the bearing presser 25. |
