A bearing structure containing: a rotary control shaft (100) having a retention part (120) extending in the axial direction from one end of a control part (110) and having a small outer diameter so as to form a step part (100S), and a drive part (130) extending further in the axial direction from the retention part (120); and a bearing (200) into which the retention part (120) is inserted, and which faces the step part (100S) at one end and has a shaft hole (230) for holding the retention part (120) in a rotatable manner. An electric machine signal control unit (600) is disposed on the other end of the bearing (200). A tapered surface (100T) extending from the central position of the step part in the radial direction to the outer circumferential surface of the retention part (120) is formed on the rotary control shaft (100). A tapered surface (200T) of which the inner diameter becomes larger towards the outside is formed on the one end of the bearing (200) at the inner circumferential edge of the shaft hole (230). A cut annular ring spring (300) is attached to the bearing (200) by being sandwiched between the tapered surfaces (100T, 200T). |
