<p>PROBLEM TO BE SOLVED: To provide a motor capable of eliminating noise generated when an outer ring of a rolling bearing collides with an inner periphery of a holder portion.SOLUTION: A tapered first taper face 56 is formed on inner peripheries of holder portions 54c, 56, holding members 57, 58 are inserted between the first tapered face 56 and an outer ring of a rolling bearing 81 in a radial direction of an output shaft 38, tapered second taper faces 57a, 58a kept into contact with the first taper face 56, are formed on the outer peripheries of the holding members, cylindrical fitting faces 57c, 58c kept into contact with an outer periphery of the outer ring of the rolling bearing 81 are formed on inner peripheries of the holding members, flange portions 57d, 58d kept into contact with an end face of the outer ring of the rolling bearing 81 are formed on the holding members in a state of projecting in an inner diameter direction, the holding members have reduction function so that the second taper faces and the fitting faces are radially reduced according to the first taper face 56, and an elastic member 95 is disposed to press the holding members in the direction to bring the second taper faces into contact with the first taper face 56 through the flange portions.</p> |
