(54) Hollow guide shaft unit, air-jet spinning device and spinning machine


(57) 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.
