進軸支持装置。[Scope of Claim for Utility Model Registration] (1) The propulsion shaft of an outboard motor or an outboard/outboard motor propulsion device is lowered by bearings press-fitted into the forward rotation bevel gear and the reverse rotation bevel gear meshed with the bevel gear of the drive shaft. In the propulsion shaft support device supported in the gear housing, a sleeve with an O-ring insertion step formed on the rear end surface is press-fitted into the outer ring of the bearing press-fitted into the reversing bevel gear, and these reversing bevel gears and the bearing are press-fitted. The sleeve is integrated into the lower gear housing through an adjustment shim and inserted into the lower gear housing with an intermediate or clearance fit, and an O-ring is inserted into the O-ring insertion step of the sleeve, and the tip side of the propulsion shaft support housing is connected to the sleeve. A propulsion shaft support device for an outboard motor or an inboard/outboard motor propulsion device, characterized in that the device is fitted between a lower gear housing. (2) The propulsion shaft is composed of a forward/reverse transmission shaft and a propeller shaft, a spline is provided at the rear end of the forward/reverse transmission shaft, the propeller shaft is provided with an internal spline that meshes with the spline, and a tapered roller bearing and a propeller shaft are provided. The propulsion shaft support device according to claim 1, wherein the propulsion shaft support device is fitted into and supported by the propulsion shaft support housing via a support housing.
