The slinger blows away foreign matter using centrifugal force to prevent foreign matter from entering the inside of the slinger, and the detection portion formed thereon also serves as a conventional pulsar ring. Therefore, the overall size is reduced and the number of parts is reduced. Further, since the sensor is attached to an annular mounting bracket that is press-fitted and fixed to the outer circumferential surface of the inner ring or the inner circumferential surface of the outer ring, the sensor mounting structure is simplified. Further, when a labyrinth is formed between the mounting bracket and the slinger, it is possible to prevent foreign matter from reaching the seal member, and the durability of the seal member can be improved.

構造が簡単で全体寸法が小さくなる。Hereinafter, the present invention will be explained in detail with reference to illustrated embodiments. FIG. 1 is a sectional view of this embodiment, and FIG. 2 is an enlarged view of the main part of FIG. 1. In FIG. 1, ■ is an inner ring consisting of a main body 2 having an outer flange 2a and an annular member 3 fitted around the stepped outer periphery of the main body 2, 5 is an outer ring having an outer flange 5a, and 6.7 is an inner ring. The poles as rolling elements are arranged in two rows between I and the outer ring 5, and 8.9 is the above-mentioned hole 6.
．． This is a holder that holds 7. One side of the space between the inner ring I and the outer ring 5 where the hole 8°9 exists is a sealing member IO.
The other side of the space is sealed by a sealing member 11. The seal member 11, as shown in FIG. It is press-fitted around the circumference and fixed. Lips 13a and 13b of this seal member 11 protrude inwardly in a V-shape, and lip 13c protrudes outward in the axial direction. A slinger 15 is press-fitted and fixed onto the outer peripheral surface of the annular member 3 of the inner ring 1. This slinger I5 has a small diameter part 16, a large diameter part 17, and a stepped part 18.
It has a stepped cylindrical shape, and its small diameter 116 is press-fitted into the outer peripheral surface of the annular member 3 and fixed. Above step part 1B
A lip +3c of the sealing member 11 extends near the step wJ+8, and a labyrinth 22 is formed between the lip 13c and the step wJ+8. Further, the large diameter portion 17 is a portion to be detected, and has slits 21 formed at equal intervals in the circumferential direction. The lips 13a and I3b of the sealing member are in sliding contact with the outer peripheral surface of the small diameter cylindrical portion 16 of the slinger 18. On the other hand, a large diameter cylindrical portion 26 of a hook-shaped cross section mounting fitting 25 having a large diameter cylinder M26 and seven small diameter cylinders 1127 is press fitted into the inner circumferential surface of the outer ring 5 into which the seal member 11 is press fitted and fixed. The end of this mounting fitting 25 is in contact with the seal member 11. A hole 29 provided in a portion of the large diameter cylindrical portion 26 that protrudes axially outward from the small diameter cylindrical portion 27 of this mounting bracket 25
In this case, the sensor 31 is press-fitted and fixed so as to face the slit 21 of the detected part ]7. A labyrinth 32 is formed between the tip of the small diameter cylindrical portion 27 of the mounting fitting 25 and the corner between the stepped portion 18 of the slinger 15 and the detected portion 17. According to the above configuration, as the inner ring l rotates, the slinger 1
5 rotates, and the centrifugal force blows off foreign matter attached to the slinger 15, preventing the foreign matter from reaching the location where the sealing member II exists, improving the durability of the sealing member II, and ball 6.7. Prevent foreign matter from entering the space where the Further, a labyrinth 22 is formed between the slinger 15 and the tip of the small diameter cylindrical portion 27 of the mounting bracket 25,
Furthermore, since the labyrinth 22 is formed between the lip 13c of the seal member 11 and the stepped portion I8, foreign matter is prevented from entering the area where the lips 13a, 13b of the seal member 11 are present. The rotation angle of the inner ring I is detected by a sensor 31 fixed to the mounting bracket 25 detecting passage of the detected portion 26 of the slinger I5 through the slit 21. As described above, in this embodiment, the slinger I5 also serves as a conventional pulser ring, and the sensor 31 is fixed by the mounting bracket 25 press-fitted into the inner peripheral surface of the outer ring 5, so that the overall dimensions are reduced. It is smaller and has fewer parts. In addition, when installing the sensor 31, the seal member 1
Since the sensor 31 is press-fitted into the hole 29 of the mounting bracket 25 that is press-fitted into the outer ring 5 in the vicinity of the outer ring 5, the sensor 31 can be easily attached. Furthermore, since the labyrinth 32 is formed between the slinger 15 and the mounting fitting 25, it is possible to prevent foreign matter from reaching the sole member 11. FIG. 3 shows another embodiment, in which the knoll member 11, slinger 15, mounting bracket 25 and sensor 31 have exactly the same structure as the embodiment shown in FIGS. 1.2. In this embodiment, the outer ring 43 is provided with a flange, and the inner ring 40 consisting of annular members 41 and 42 is also not provided with a flange, and each has a substantially simple cylindrical shape. Rolling elements 45 and 46 are arranged between the inner ring 40 and the outer ring 43, and the side opposite to the seal member 11 is sealed with a seal member 47. The above slinger 15. The functions of the mounting bracket 25 and the sensor are exactly the same as in FIG. 1.2. FIG. 4 shows the main part of another embodiment. A cylindrical portion 52 of an annular slinger 51 having an angular cross-section is press-fitted into the outer peripheral surface of the inner ring 1 and fixed thereto. The end face 53 of this slinger 51 is provided with axial through holes 55 at equal intervals in the circumferential direction. On the outer periphery of the cylindrical portion 52 of this slinger 53,
Lips 13a and 13b of the seal member 11 press-fitted and fixed to the inner peripheral surface of the outer ring 5 come into sliding contact. Further, a labyrinth 60 is formed between the lip 13c of the sealing member 11 and the end surface 53.
is formed. On the other hand, a cylindrical part 57 of a mounting bracket 56 having an angular cross-section is press-fitted into the inner circumferential surface of the outer ring 5 and fixed, and a through-hole 59 is provided in the inner flange part 58 facing the pitch circle in which the through-hole 55 exists. A sensor 61 is inserted into this through hole 59 and fixed. Therefore, as the inner ring 1 rotates, the slinger 51
The through hole 55 passes in front of the sensor 61, and the rotation angle of the inner ring 1 can be detected by the sensor 61. Also,
A labyrinth 61 formed between the end face of the slinger 51, that is, the tip of the outer flange 53 and the inner circumference of the cylindrical portion 57 of the mounting bracket 56, and a labyrinth 60 formed between the lip 13c of the sealing member 11 and the slinger 51. , it is possible to prevent foreign matter from reaching the lips 13a and +3b. In this embodiment as well, the slinger 51 provided at the location where the seal member 11 is present also serves as a conventional pulser ring, so the overall size is reduced and the number of parts is reduced. Further, the sensor 61 is connected to the sole member 1
Since the sensor 61 is fixed to the outer ring 5 by a mounting fitting 56 press-fitted into the inner circumferential surface of the outer ring 5 in the vicinity of 1, the mounting structure of the sensor 61 is simple and the overall size is small.

Since the mounting bracket that fixes the sensor facing the detected part of the slinger is press-fitted and fixed, the slinger doubles as a conventional pulser ring, and therefore the overall size is smaller and the number of parts is reduced. Therefore, the sensor can be installed with a simple structure.
