PROBLEM TO BE SOLVED: To stabilize a behavior of a driven gear for transmitting rotational power and suppress displacement.SOLUTION: An outboard motor 1 comprises: a first driven gear 32 and a second driven gear 51 which are engaged with a drive gear 31 which rotates and to which rotational power is transmitted from an engine unit 14; a first taper-roller bearing 52 and a second taper-roller bearing 53 arranged in a cross direction in a manner of facing opposite orientations each other on an outer periphery of a cylindrical part 513 of the second driven gear 51; and a nut 544 which is provided so as to freely displace in an axial direction, on the outer periphery of the cylindrical part 513 of the second driven gear 51. By the nut 544, a preload can be applied to the first taper-roller bearing 52 and the second taper-roller bearing 53, and the first taper-roller bearing 52 and the second taper-roller bearing 53 can be held to the outer periphery of the cylindrical part 513 of the second driven gear 51.SELECTED DRAWING: Figure 3

    【課題】回転動力を伝達する被動歯車の挙動の安定と変位の抑制を図る。【解決手段】船外機1は、エンジンユニット14から回転動力が伝達されて回転する駆動歯車31と噛み合う第1の被動歯車32および第2の被動歯車51と、第2の被動歯車51の筒状部513の外周に互いに反対向きで前後方向に並べて設けられる第1の円錐ころ軸受52と第2の円錐ころ軸受53と、第2の被動歯車51の筒状部513の外周に軸線方向に変位可能に設けられるナット544とを有し、ナット544によって、第1の円錐ころ軸受52と第2の円錐ころ軸受53とに予圧を掛けるとともに、第1の円錐ころ軸受52と第2の円錐ころ軸受53とを第2の被動歯車51の筒状部513の外周に保持する。【選択図】図3
