Of the cover 10, the cylindrical portion 10 of the cover 10
A projection 19 having a substantially triangular cross section is formed radially outward on b, and the internal space of the projection 19 is a grease reservoir 20. Further, a plurality of holes 21 are formed on the circumference of the protruding portion 19 to communicate the protruding portion internal space (grease reservoir) 20 and the inside of the bearing. In this embodiment, since the outer peripheral surface of the projecting portion 19 is the inclined surface 22, the grease inside the bearing is circulated and guided to the outer ring 1 side by the centrifugal force at the time of rotation of the bearing, thereby preventing the grease from leaking. Even if the grease leaks, the grease is held by the grease reservoir 20 of the cover 10, so that leakage to the outside of the bearing is prevented. Furthermore, since the projection 21 has the hole 21 formed therein, the grease stored in the grease reservoir 20 is returned to the inside of the bearing by centrifugal force when the bearing rotates, so that grease leakage to the outside of the bearing is further prevented. Is done.
