けなければならないため、取付け工数大により、コスト
アツプの要因となつていた。For the cover 3, for example, a mylar or the like must be prepared by attaching it with a double-sided adhesive tape or the like, or a cylindrical one must be attached, which causes a cost increase due to the large number of attachment steps.
経時変化により、両面接着の剥離及び圧入取付の抜
け、割れにより、電磁クラツチの摩擦面にカバー３が抜
け落ち、２次障害発生の原因となつていた。Due to the change over time, peeling of the double-sided adhesive and disconnection and cracking of the press-fitting attachment caused the cover 3 to slip off on the friction surface of the electromagnetic clutch, causing a secondary failure.
本考案者は上述の問題点について種々検討し、本考案を
見出したものである。The present inventor has made various studies on the above problems and found the present invention.
即ち、本考案の目的とする所は、 外部粉塵、油の進入を防止し、クラツチ特性に影響を
与えないカバーを提供すること、 取付が容易でローコストなカバーを提供すること、 経時変化のない安定したカバーを提供すること、 等である。In other words, the object of the present invention is to provide a cover that prevents external dust and oil from entering and does not affect the clutch characteristics, provide a cover that is easy to install and low cost, and does not change over time. Providing a stable cover, etc.
