To provide an abnormal sound prevention structure of a curtain unit that does not generate abnormal sound from an arm.SOLUTION: In a shank 33, a side face on a tip 36 side in an axial direction of the shank 33 of a bottomed groove 35b is so made as to be a first engagement part 37a, and a step surface connecting a large diameter part 34 and a small diameter part 35 is so made as to be a second engagement part 37b. In a bushing 40, a tip side face of a protrusion 44 is so made as to be a first engaged part 45a which can engage with the first engagement part 37a, and a step surface connecting a large inner diameter part 40a and a small inner diameter part 40b is so made as to be a second engaged part 45b which engages with the second engagement part 37b. In an assembled state, the first engagement part 37a and the first engaged part 45a, and the second engagement part 37a and the second engaged part 45b are engaged, whereby movement of the bushing 40 in the axial direction of the shank 33 is regulated, an arm part 43 is so arranged as to face the bottomed groove 35b, and a gap is provided between the arm part 43 and the shank 33.SELECTED DRAWING: Figure 4
【課題】アームからの異音を発生させないカーテンユニットの異音防止構造を提供する。【解決手段】軸部33は、有底溝35bの軸部33の軸線方向における先端部36側の側面が第一係合部37aとされ、大径部34と、小径部35とを繋ぐ段差面が第二係合部37bとされる。ブッシュ40は、突部44の先端側面が、第一係合部37aと係合可能な第一被係合部45aとされ、大内径部40aと小内径部40bとを繋ぐ段差面が、第二係合部37bと係合可能な第二被係合部45bとされる。組み付けられた状態において、第一係合部37aと第一被係合部45a、第二係合部37bと第二被係合部45bが、係合されることで、ブッシュ40が軸部33の軸線方向への移動を規制され、アーム部43が有底溝35bと対向するように配され、アーム部43と軸部33との間に隙間を有するように配設されている。【選択図】図4
