A bearing unit includes a shaft, a tubular bearing member, a planar plate fixed to a lower side of the bearing member and a lubricant filled between the shaft and an inner circumferential surface of the bearing member. In the bearing member, an inner circumferential wall portion is axially downwardly protruding from a lower surface of the bearing member and has a first surface contacting with and extending in a parallel with an upper surface of the plate and a second surface axially spaced apart from the upper surface of the plate. An outer circumferential wall portion is positioned radially outwardly of the second surface. The plate is fixed to the outer circumferential wall portion of the bearing member, and a radial inner side of the inner circumferential wall portion communicates with the outer circumferential wall portion through a gap formed between the second surface and the slate.
