Description

このシールリング10は、薄鋼板を曲げ形成する事により全体を円輪状に形成して成る芯金11と、ゴムの如きエラストマー等の弾性材により造られ、この芯金11により補強されたシール材12とから成る。このうちの芯金11は、外周縁部に形成した断面略C字形の折り返し部13を、上記係止溝8に係止する事により、上記外輪3の一端部内周面に係止している。又、上記シール材12は、上記折り返し部13の内外両周面部分を含む、上記芯金11の外径寄り部分の他、この芯金11の内径寄り部分にも添着している。このうち、内径寄り部分に添着したシール材12の一部は、上記芯金11の内周縁よりも直径方向内方に突出して、内径を弾性的に拡縮自在なシールリップ14を構成している。そして、このシールリップ14の内周縁部を、上記1対の傾斜面9、9のうちの一端側の傾斜面9に、全周に亙り弾性的に当接させている。この構成により、上記シールリング10が、上記外輪3の一端部内周面と上記内輪5の一端部外周面とを、全周に亙り塞いでいる。 The seal ring 10 is made of a core metal 11 formed by bending a thin steel plate to form an entire ring shape, and an elastic material such as an elastomer such as rubber, and is reinforced by the core metal 11. It consists of twelve. Of these, the core metal 11 is locked to the inner peripheral surface of one end of the outer ring 3 by locking the folded-back portion 13 having a substantially C-shaped cross section formed on the outer peripheral edge portion to the locking groove 8. .. Further, the sealing material 12 is attached not only to the outer diameter side portion of the core metal 11 including the inner and outer peripheral surface portions of the folded portion 13, but also to the inner diameter side portion of the core metal 11. Of these, a part of the sealing material 12 attached to the portion closer to the inner diameter protrudes inward in the radial direction from the inner peripheral edge of the core metal 11 to form a sealing lip 14 whose inner diameter can be elastically expanded or contracted. .. Then, the inner peripheral edge portion of the seal lip 14 is elastically brought into contact with the inclined surface 9 on one end side of the pair of inclined surfaces 9 and 9 over the entire circumference. With this configuration, the seal ring 10 covers the inner peripheral surface of one end of the outer ring 3 and the outer peripheral surface of one end of the inner ring 5 all around.
