PROBLEM TO BE SOLVED: To provide a double row ball bearing whose torque is small and a pinion shaft support device for a vehicle whose operation cost is low.SOLUTION: A radial dimension of a first annular part 150 of a first retainer 140 is larger than the value obtained by adding a radial dimension of a second annular part 151 of the first retainer 140 and a radial dimension of a third annular part 152 of the first retainer 140. A second columnar part 174 of a second retainer 141 has an inner surface constituted of a part of a conical surface increased in the inner diameter thereof as going to the outer side in the axial direction. A liquid inflow suppression part includes an end surface of the radial outer side of the first annular part 150 of the first retainer 140, and a liquid outflow promotion part includes the inner surface of the second columnar part 174 of the second retainer 141. |
