It has a plurality of outward flanges 63 that are divided by circumferential grooves 62 and extend outward in the radial direction, and the outer ring side seal member 66 seals between the opposing joint surfaces of the split member that is divided into two in the circumferential direction. A seal holding ring 65 that is connected and connected in a divisible manner with a piece interposed therebetween, and a seal body 64 that has an end or is divided into an appropriate number of pieces held on the inner diameter side of the seal holding member 65.
The seal body 64 has a fixed part 641 held by the seal holding ring 65, and a plurality of inward flanges 643 separated by concave circumferential grooves 642 on the inner diameter side of the fixed part 641. A sealing device for a rolling bearing, in which the inward flanges 643 and the outward flanges 63 are assembled alternately in the axial direction to form a sealing portion 6 between them. (2) In paragraph 1 of the claims for utility model registration,
A sealing device for a rolling bearing in which the sealing portion 6 is a non-contact labyrinth seal. (3) In paragraph 1 of the claims for utility model registration,
A sealing device for a rolling bearing in which the sealing portion 6 is a contact type seal. (4) In paragraph 1 of the claims for utility model registration,
A sealing device for a rolling bearing in which the sealing part 6 is a combination type seal of non-contact and contact. (5) Scope of claims for utility model registration, paragraphs 1 to 4
In any of the above, the seal body 64 is made of rubber,
A sealing device for rolling bearings made of an elastic material such as synthetic resin. (6) Scope of claims for utility model registration, paragraphs 1 to 5
In any of the following paragraphs, the rolling bearing sealing device is a four-row tapered roller bearing. (7) Scope of claims for utility model registration, paragraphs 1 to 6
In any of the above items, the seal holding member 65 constituting a part of the outer ring side seal member 66 is spigot-locked to the end face of the single-row outer ring 3, and
