<p>PROBLEM TO BE SOLVED: To provide a rotary device that facilitates removal of a rolling bearing from a rotary shaft.SOLUTION: A rotary device includes a housing 10, a rolling bearing 70 that is fitted to an inner periphery of the housing 10, and a rotary shaft 20 that is fitted to an inner periphery of the rolling bearing 70. The rolling bearing 70 includes a ring-shaped outer ring 71, a ring-shaped inner ring 72 that is disposed on an inner periphery of the outer ring 71, and rolling elements 73. The inner periphery of the housing 10 is formed with a first fitting surface 13 to which the outer periphery of the outer ring 71 is fitted, and formed with a first step surface on which one end surface of the outer ring 71 abuts. The outer periphery of the rotary shaft 20 is formed with a second fitting surface 27 to which the inner periphery of the inner ring 72 is fitted, and formed with a third step surface 26 on which one end surface of the inner ring 72 abuts. The outer periphery of the rotary shaft 20 is formed with a male screw part 25. The male screw part 25 is screwed with a nut 85, and the nut 85 is moved to the housing 10 side while rotating the nut 85 from a state where the other end surface of the nut 85 abuts on one end surface of the housing 10.</p> |
