First closing plate and second closing plate close opening portions at both ends of cylindrical member in an axial direction. Base is housed in a space formed by cylindrical member, first closing plate, and second closing plate, and rotates around an axis in the same direction as the axial direction of cylindrical member. Resin layers are formed on thrust surfaces of base. Groove C is a plurality of concentric circular grooves or a spiral groove formed on each resin layer, and the center of circles of the circular grooves or the center of a spiral of the spiral groove is different from the rotation center of base.
