<P>PROBLEM TO BE SOLVED: To provide a rolling bearing apparatus with a pulley capable of preventing muddy water or dust having entered an opening between a cover member and a seal member from accumulating. <P>SOLUTION: This apparatus includes a rolling bearing 20, the seal member 60, a pulley member 70 and the cover member 80. The cover member 80 includes: an inner diameter side annular part 82 disposed on an inner wheel 30 or a shaft member 10 of the rolling bearing 20; an inner diameter side cylindrical part 83 formed at an outer radial end of the inner diameter side annular part 82; an outer diameter side annular part 86 extending radially outward from an end of the inner diameter side cylindrical part 83; and an outer diameter side sheathing part 87 extending from the outer radial end of the outer diameter side annular part 86 toward a circumference of an inner diameter side cylindrical part 71 of the pulley member 70. An annular concaved portion 84 for receiving and discharging the muddy water or the like entering from the opening between the cover member 80 and the seal member 70 is formed on a circumferential side of the inner diameter side cylindrical part 83. <P>COPYRIGHT: (C)2012,JPO&INPIT |
