Title:
EXTERNAL FORCE ABSORPTION DEVICE AND DRIVE DEVICE
Document Type and Number:
WIPO Patent Application WO/2018/003414
Kind Code:
A1
Abstract:
An external force absorption device which can absorb an external force applied to a driven member, and a drive device are provided. An external force absorption mechanism (9) (the external force absorption device) comprises a driven member (3) which is rotatably supported on a support shaft (35) via a holder (31), a first support member (81) which cannot rotate relative to the support shaft (35), and a second support member (82) which is rotatably supported on the support shaft (35). Further, the external force absorption mechanism (9) also comprises a first biasing member (91) which biases a second support member (82) in one direction (R351) around the support shaft (35), a contact member (85) which restricts rotation of the second support member (82) in one direction (R351) around the support shaft (35), and a second biasing member (92) which is provided between the second support member (82) and the driven member (3). The second biasing member (92) applies to the driven member (3) a biasing force resisting relative rotation of the driven member (3) about the support shaft (35) with respect to the second support member (82).
