A propeller apparatus of a ship propulsion machine includes a tubular member inserted into an insertion hole so as to be movable in a circumferential direction with respect to a hub. First concave portions arranged in a circumferential direction are formed in an outer peripheral surface of the tubular member. Second concave portions arranged in the circumferential direction so as to respectively face the first concave portions are formed in an inner peripheral surface of the insertion hole. Each of the elastic bodies has a spherical or columnar shape, a first portion of each of the elastic bodies is disposed in each of the first concave portions, a second portion of each of the elastic bodies is disposed in each of the second concave portions, and the elastic bodies are rotatably held between the first concave portions and the second concave portions facing each other.
