Title:
BEARING STRUCTURE FOR ROTARY CONTROL-TYPE ELECTRONIC COMPONENT
Document Type and Number:
WIPO Patent Application WO/2013/065506
Kind Code:
A1
Abstract:
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) for controlling signals by means of the rotation of a rotor (700) secured to the drive part (130) is disposed on the other end of the bearing (200). 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). An elastic ring (300) is attached to the retention part (120) by being elastically sandwiched between the tapered surface (200T) and the step part (100S).
