Abstract

　静音効果が高く、シールの位置合わせ作業の不要な転動装置を得る。 　転動装置は、内方部材と、外方部材と、これら内方部材と外方部材との間に転動自在に配設される複数の転動体とを備えることにより、内方部材に対する外方部材の相対的な回転運動又は直線運動を自在とした装置である。このような転動装置において、外方部材の端部にはエンドプレート２４が設置されている。そして、このエンドプレート２４は、エンドプレート本体部２４ａと、外方部材との当接面に設置されるパッキン部材２４ｃと、内方部材に対して隙間なく摺接するように設置されるシール部材２４ｂとを備えており、さらに、エンドプレート本体部２４ａ、パッキン部材２４ｃおよびシール部材２４ｂが一体成形されている。
