Abstract
A drive device with an abnormality detection mechanism may include a drive source; a drive member to which power of the drive source is transmitted; a driven member operably coupled to the drive member; and a detector structured to output a signal in response to the driven member being turned in the second direction around the second axial line. The driven member may be structured such that, in response to the drive member being turned in a first direction around a first axial line, the driven member is turned in a first direction around a second axial line; and, in response to transmission of the power from the drive member being disconnected, the driven member is turned in a second direction around the second axial line.
Claims16
A drive device with an abnormality detection mechanism comprising:
- a drive source;
- a drive member to which power of the drive source is transmitted;
- a driven member operably coupled to the drive member and structured such that:
- in response to the drive member being turned in a first direction around a first axial line, the driven member is turned in a first direction around a second axial line;
- and
- in response to transmission of the power from the drive member being disconnected, the driven member is turned in a second direction around the second axial line, and
- a detector structured to output a signal in response to the driven member being turned in the second direction around the second axial line, wherein a signal outputted in a normal state that the driven member is normally turned is different from a signal outputted in an abnormal state that turning of the driven member is prevented.
A damper device comprising:
- a drive device with an abnormality detection mechanism comprising:
- a drive source;
- a drive member to which power of the drive source is transmitted;
- a driven member operably coupled to the drive member and structured such that:
- in response to the drive member being turned in a first direction around a first axial line, the driven member is turned in a first direction around a second axial line;
- and
- in response to transmission of the power from the drive member being disconnected, the driven member is turned in a second direction around the second axial line, and
- a detector structured to output a signal in response to the driven member being turned in the second direction around the second axial line, wherein a signal outputted in a normal state that the driven member is normally turned is different from a signal outputted in an abnormal state that turning of the driven member is prevented
- a baffle which is turnable around the second axial line together with the driven member;
- and
- a frame comprising an opening part which is opened and closed by the baffle.
