PURPOSE:To improve the universality of a supporting system, by making a supporting point of an arm supporting a propeller body on the support bracket attached to the hull variable and making a tilting locus of the propeller body also variable. CONSTITUTION:A swivel bracket 3 is supported on a clamp bracket 2 via both upper and lower arms 7 and 9. An end of the upper arm 7 is rotatably connected to an upper part of the clamp bracket 2 by a support pin 9, while the other end is rotatably connected to an upper part of the swivel bracket 3 by a support pin 10 as well. On the other hand, one end of the lower arm 8 selects one of two support holes 13 formed in the clamp bracket 2 and is rotatably supported in a pivotal manner together with an intermediate arm 12 by a support pin 11, while the other end is rotatably connected to a lower part of the swivel bracket 3 by a support pin 14. |
