摘要

A spindle unit (35) of a spinning device (9) includes a spindle (24), a holder main body (152), a lock member (153), and a spring section (183) . The spindle (24) includes a tip-end portion (30) for receiving an insert of a twisted fiber bundle, and a fiber passage (85) for receiving a passing of the inserted fiber bundle . The holder main body (152) supports the spindle (24). The lock member (153) mechanically couples the spindle (24) with the holder main body (152) . The spring section (183) generates force to act upon the spindle (24) so as to displace the tip-end portion (30) towards one side within a movable range under a state in which the spindle (24) is mechanically coupled with the holder main body (152) via the lock member (153) , the movable range being a range in which the tip-end portion (30) of the spindle (24) can be moved.
