In addition to the two axial lips 32, 33, a radial lip 34 is attached. As a result, since the outer seal 3 and the outer ring 21 of the outer ring 21 are inserted into the annular groove 52, the overall axial length of the vehicle bearing device 5 can be further shortened, and the radial lip 34 is added. The outer seal 3 has an annular groove 5
Since it goes into 2, the sealability of the vehicle bearing device 5 is further improved, which is preferable. (2) In the above embodiment, the vehicle bearing device 5 is provided with the double row outward tapered roller bearing 2 as an example, but instead of this, a vehicle bearing provided with any other type of rolling bearing. A device is mentioned. For example, as shown in FIG.
Instead of the rolling elements of the tapered rollers 22a, 22b, balls 26a,
The vehicle bearing device 6 and the like are provided with the double-row outward angular ball bearing 20 of 26 b.

作業コストの低減に貢献できるようになる。As described above, in the vehicle bearing device according to the first aspect of the invention, the outer seal is attached to the end of the outer ring of the outer ring on the vehicle outer side. In the above, since the outer seal can be preliminarily attached to the outer ring before the outer ring is assembled to the hub wheel, the assembly work of the vehicle bearing device becomes easy and the number of manufacturing steps can be reduced.
It becomes possible to contribute to the reduction of work cost.

Along with this, the degree of freedom in designing a vehicle equipped with this device is increased, and it is expected that the usage will be expanded. In addition, since it can contribute to the weight reduction of this device, it becomes possible to improve the fuel consumption of the vehicle using this device.

Also, the weight can be reduced. Also, as the outer seal enters the annular groove,
It is preferable because the sealing property can be improved.
