PURPOSE:To reduce size and weight, to simplify operation, and to increase a response speed by a method wherein a variable pitch propeller device for an outboard motor for a small high speed ship comprises a rack engaged with a pinion and a rack operating means to reciprocate the rack, and through operation of the rack operating means, the pitch angle of a propeller is varied. CONSTITUTION:When a rack 46 is operated by means of a rack operating means and an adjust screw 37 is rotated by means of a pinion 45 engaged with the rack 46, a screw part 37A is joined in a screwed-in state with a fixed nut 42, whereby the adjust screw 37 is reciprocated through rotation. Thereby, a control rod 35 coupled to an adjust screw 37 through a bearing 36 is reciprocated. A link 39 coupled through a pin 38 is pulled and closed and a propeller 40 is rotated around a rotary shaft 41 through an eccentric pin 43 coupled to the link 39. This constitution changes the pitch angle of the propeller 40. |
