To provide a wind direction adjustment device capable of appropriately generating operation torque of a blade member with respect to a housing to obtain excellent operability of a blade member.SOLUTION: A wind direction adjustment device has a housing and a blade member rotatably connected to the housing. On one of the housing and the blade member, a rotary shaft part is provided, and on the other one, a bearing part 30 for supporting the rotary shaft part is provided. The bearing part 30 has a bush body 40 having elasticity, and a holding part 50 for accommodating and holding the bush body 40. On the outer peripheral side surface of a bush main body 41 in the bush body 40, a plurality of concave parts and convex parts 47 are alternately provided in a rotation direction of the rotary shaft part, and a bottom surface 46a of the concave part is formed on an arcuate curved surface.SELECTED DRAWING: Figure 4
