• a seal member provided proximate a side of the inner periphery supporting the bearing in an inner periphery of the annular support member, the seal member coming into slidable contact with an outer periphery of the stopper means;
• an outer end extending to an outer side in the axial direction of the annular support member, the outer end outer side being positioned proximate to an outer shell of the stopper means, and a gap is formed between the outer end outer side and the outer shell of the stopper means, the gap forms a labyrinth seal;
• wherein an outer periphery of the outer end of the annular support member is formed as an expanded portion, a diameter of the expanded portion increasing towards a periphery of the expanded portion in an axial direction, the expanded portion ending at said outer side.
