Abstract
Example embodiments include a driving device having: a plurality of vibrating members that may vibrate when the vibrating members are driven; and a holding part that may hold the vibrating members. The holding part may include a first member with which one or more of the vibrating members may be brought into contact, and a second member with which one or more of the vibrating members may be brought into contact. The first member and the second member may be partially coupled to each other. A grounding member for electrically grounding a member held by the holding part may be brought into contact with one of the first member and the second member that is more difficult to vibrate.
Claims11
A driving device comprising:
- a driving source;
- a plurality of vibrating members that vibrate when the plurality of vibrating members are driven, the plurality of vibrating members including an internal gear;
- and
- a holding part configured to hold the plurality of vibrating members, wherein
- the holding part includes a first member in which one or more vibrating members of the plurality of vibrating members are brought into contact, and a second member with which one or more vibrating members of the plurality of vibrating members are brought into contact,
- the first member and the second member are partially coupled to each other;
- and
- a grounding member configured to electrically ground a member held by the holding part, the grounding member contacting one of the first member and the second member that is more difficult to vibrate.
A driving device comprising:
- a driving source;
- one or more vibrating members that vibrate when the one or more vibrating members are driven, the one or more vibrating members including an internal gear;
- and
- a holding part configured to hold the one or more vibrating members, wherein
- the holding part includes a first member and a second member with which the one or more vibrating members are brought into contact,
- the first member and the second member are overlapped with each other and are partially coupled to each other,
- the first member and the second member are coupled at three or more coupled portions, and
- the one or more vibrating members abut against the first member and the second member inside a polygon formed by connecting the three or more coupled portions.
