PROBLEM TO BE SOLVED: To inhibit a bearing member from rotating around a center axis relative to an elastic member.SOLUTION: A bearing device 25 includes: an annular bearing member which rotatably supports a shaft 31 extending vertically along a center axis 9; and an annular elastic member which surrounds a radial outer side of the bearing member and has higher elasticity than the bearing member. An outer peripheral surface of the bearing member and an inner peripheral surface of the elastic member at least partially contact with each other. The bearing member has a protruding part 55 which protrudes radially outward from the outer peripheral surface. On the other hand, the elastic member includes a groove part 62 which is recessed radially outward from the inner peripheral surface. The protruding part of the bearing member is disposed in the groove part of the elastic member.SELECTED DRAWING: Figure 3 |
