PROBLEM TO BE SOLVED: To provide a thumb-turn device that furthermore enhances air tightness of a gap between a thumb-turn shaft and a fixed cylinder, and enables the thumb-turn shaft to rotate smoothly during locking and unlocking.SOLUTION: A thumb-turn device includes: a thumb-turn shaft 7 rotatably held in a fixation cylinder 6; an annular plate type oil seal 9 fitted in a receiving space between an outer circumferential surface of the thumb-turn shaft 7 and an inner circumferential surface of the fixation cylinder 6; a water stop elastic body 11 where an inner circumferential surface of a central opening is externally fitted in an adherence state in the outer circumferential surface of the fixation cylinder 6, and a vertical inside surface becomes a contact state to an inner wall surface of an opening/closing member 1; and a tightening cylindrical screw 12 screwed in the male screw section of the fixation cylinder 6 so that the vertical inside surface of the water stop elastic body 11 may be brought into press-contact with the inner wall surface of the opening/closing member 1.SELECTED DRAWING: Figure 1
【課題】サムターン軸と固定筒との隙間の気密性をより一層高めると共に、施・解錠時、サムターン軸が滑らかに回転するサムターン装置を提供する。【解決手段】固定筒６に回転可能に保持されるサムターン軸７と、サムターン軸７の外周面と固定筒６の内周面との間の収納空間に嵌め込まれる環状板型オイルシール９と、中央開口の内周面が固定筒６の外周面に密着状態に外嵌合すると共に垂直内側面が開閉体１の内壁面に対して接触状態となる止水弾性体１１と、止水弾性体１１の垂直内側面が開閉体１の内壁面に圧接するように固定筒６のオネジ部に螺合する締付け筒状螺合体１２を備えるサムターン装置。【選択図】図１
