Abstract
A sleeve 18 spline-fitted in an outer periphery of a propeller shaft 4 is connected to a propeller boss 12 for surrounding the outer periphery of the sleeve by a damper rubber 20 interposed in superposed relation therebetween, and in a recess formed in the outer periphery of the propeller boss 12 so that a bottom surface thereof comes near the outer periphery of the damper rubber 20, propeller blades are rotatably supported on a blade shaft 33 parallel to the propeller shaft 4. With this arrangement, it is possible to provide a compact variable propeller for a boat which can be mounted on a relatively short propeller shaft and which is provided with a torque limiting device.
