PROBLEM TO BE SOLVED: To lessen rotational vibration, reduce the number of parts items, and make the propeller light in weight and small in size. SOLUTION: This propeller is equipped with a casing at the lower part of the propeller, a power transmitting mechanism 20 transmitting power to the propeller, and with a forward/reverse change-over mechanism 21 making chanceover for shifting for forward movement, reverse movement and a neutral position. In this case, a bush 40 is engaged with a propeller shaft 33 driving the propeller by way of a damper 47 in such a way that it can be integrally rotated, and a part of the outer circumference of the bush 40 is brought into contact with the inner circumference of the boss part 7a of the propeller. |
