Claims

[Scope of Claim for Utility Model Registration] (1) A forward rotation bevel gear and a reverse rotation bevel gear each having a clutch engaging portion are supported in a lower gear housing facing each other via bearings, and an outboard motor, an inboard/outboard motor A propulsion shaft support for an outboard motor, an outboard motor, which has a propulsion shaft that meshes with a bevel gear provided on the propulsion drive shaft of the engine, and has a clutch body slidably disposed on the forward rotation and reverse rotation bevel gears. A propulsion shaft support structure for an outboard motor or an inboard/outboard motor, characterized in that the bearing of the normal rotation bevel gear is fitted with a gap into a wear-resistant sleeve press-fitted into the lower gear housing. (2) A bevel gear for forward rotation and a bevel gear for reverse rotation, each equipped with a clutch engagement portion, are supported in a lower gear housing facing each other via bearings, and are also provided on the propulsion drive shaft of an outboard motor or an inboard/outboard motor. In a propulsion shaft support structure for an outboard motor or an outboard motor, the propulsion shaft support structure for an outboard motor or inboard/outboard motor has a propulsion shaft that meshes with a bevel gear and has a clutch body slidably disposed on the forward rotation and reverse rotation bevel gears. A propulsion shaft support structure for an outboard motor or an inboard/outboard motor, characterized in that a threaded bolt presses an outer race of a bearing of the normal rotation bevel gear to prevent rotation. (3) The propulsion shaft support structure for an outboard motor or an outboard motor according to claim 2, further comprising a rotation preventing friction member interposed between the tip end surface of the bolt and the outer peripheral surface of the outer race of the bearing.
