To provide an outboard motor and a damper member for a propeller unit capable of suppressing an increase in replacement frequency of the damper member by suppressing an increase in consumed amount of bushing.SOLUTION: An outboard motor 100 includes a propeller shaft 5 and a propeller unit 6. The propeller unit 6 includes a damper member 10, a cylindrical unit 20, and a blade unit 30. The damper member 10 includes: a bush 60 fixed in the periphery of the propeller shaft 5 and having a bush direction pushing surface 62a for pushing a cylindrical direction pushing surface 52a of an inner periphery surface 50b of the cylindrical unit 20 in the circumferential direction; an elastic member 11 for engaging with the inner periphery surface 50b of the cylindrical unit 20 to be capable of elastic deformation; and a reinforcing member 70 formed separately from the bush 60 and arranged between the bush direction pushing surface 62a and the cylindrical direction pushing surface 52a.SELECTED DRAWING: Figure 7
【課題】ブッシュの摩耗量の増大を抑制することにより、ダンパー部材の交換頻度の増大を抑制することが可能な船外機およびプロペラユニット用のダンパー部材を提供する。【解決手段】この船外機100は、プロペラシャフト5とプロペラユニット6とを備える。プロペラユニット6は、ダンパー部材10と筒状部20と羽根部30とを含む。ダンパー部材10は、プロペラシャフト5の周囲に固定され、筒状部20の内周面50bの筒方押圧面52aを周方向に押圧するブッシュ方押圧面62aを有するブッシュ60と、筒状部20の内周面50bに弾性変形可能に係合する弾性部材11と、ブッシュ60とは別個に形成され、ブッシュ方押圧面62aと筒方押圧面52aとの間に配置されている補強部材70とを有する。【選択図】図7
