To provide a rotation transmission device capable of operating stably in an environment in which foreign matter such as slurry may adhere.SOLUTION: A rotation transmission device comprises: an input shaft 3 with one end housed in a case 2; an output shaft 4 arranged on the same straight line as the input shaft 3; an inner ring 5 provided in a housing portion of the input shaft 3 in the case 2; an outer ring 6 formed into an annular shape so as to surround the inner ring 5; rollers 7a, 7b incorporated between the inner circumference of the outer ring 6 and the outer circumference of the inner ring 5; an armature 31 supported so as to move in the axial direction by energization of an electromagnet 30; and a ball lamp mechanism 33 that converts the axial movement of the armature 31 into the movement of a roller holding 8 from an engagement position to a disengagement position. The rotation transmission device is provided with a cover member 42 of an aluminum ring plate, an O ring 55, and an oil seal 57.SELECTED DRAWING: Figure 1
【課題】泥水などの異物が付着するおそれのある環境で安定して動作する回転伝達装置を提供する。【解決手段】一端がケース2内に収容された入力軸3と、入力軸3と同一直線上に配置された出力軸4と、入力軸3のケース2内への収容部分に設けられた内輪5と、内輪5を囲む環状に形成された外輪6と、外輪6の内周と内輪5の外周との間に組み込まれたローラ7a,7bと、電磁石30の通電により軸方向に移動するように支持されたアーマチュア31と、アーマチュア31の軸方向の移動を、ローラ保持器8が係合位置から係合解除位置に移動する動作に変換するボールランプ機構33とを有する回転伝達装置において、アルミ製の環板のカバー部材42とOリング55とオイルシール57とを設ける。【選択図】図1
