Beschreibung
Zusammenfassung:	A driving device includes: a shaft; and a cylindrical bush having an insertion hole into which the shaft can be inserted. The insertion hole includes an opening portion having an inner diameter decreasing from a first end surface toward a second end surface of the bush, and a small-diameter hole portion extending from an end of the opening portion to the second end surface. The shaft includes a shaft portion having an outer diameter smaller than an inner diameter of the small-diameter hole portion, and an abutment portion having an outer diameter greater than the inner diameter of the small-diameter hole portion. The bush has a sealing surface defining the opening portion. The abutment portion of the shaft abuts on the sealing surface of the bush in an axial direction of the insertion hole to seal a gap formed between the shaft and the bush inside the insertion hole.
