PROBLEM TO BE SOLVED: To provide a driving device capable of restraining the occurrence of abnormal sound caused by irregularly repeated rotation and stop of a flat washer.SOLUTION: A driving device comprises a first flat washer 27 constituting a thrust bearing by sliding and making contact with an end part side in the axial direction of a driving shaft 24, and a housing 29 having a second receiving part 29B in which the first flat washer 27 is accommodated and an engaging part 29C provided in the second receiving part 29B and being engageable with an outer periphery 27A of the first flat washer 27. Thus, since the first flat washer 27 housed in the second receiving part 29B engages with the engaging part 29C provided in the second receiving part 29B, rotation of the first flat washer 27 is regulated. Accordingly, the occurrence of abnormal sound caused by irregularly repeated rotation and stop of the first flat washer 27 can be restrained.SELECTED DRAWING: Figure 8

    【課題】 平ワッシャが回転及び停止を不定期に繰り返すことに起因する異音の発生を抑制可能な駆動装置を提供する。【解決手段】 駆動軸24の軸線方向端部側に滑り接触してスラスト軸受を構成する第1平ワッシャ27と、第1平ワッシャ27が収納される第2収納部29Bを有するとともに、当該第1平ワッシャ27の外周27Aと係合可能な係合部29Cが第2収納部29Bに設けられたハウジング29とを備える。これにより、第2収納部29Bに収納された第1平ワッシャ27は、当該第2収納部29Bに設けられた係合部29Cに係合するので、当該第1平ワッシャ27の回転が規制される。したがって、第1平ワッシャ27が回転及び停止を不定期に繰り返すことに起因する異音の発生を抑制でき得る。【選択図】図8
