In a reel 24 of a lanyard, a cam 46 is rotatable to change an orientation among a free orientation, a locking orientation, and a waiting orientation. The free orientation represents an orientation in which the cam 46 can be rotated in any of directions. The locking orientation represents an orientation in which a locking engagement portion 82 engages with a latching portion 96 of a cam receiver 52. The waiting orientation represents an orientation in which a waiting engagement portion 84 engages with a plate spring 48. When the bobbin rotates in one direction, the cam 46 changes from the free orientation to the waiting orientation. When the bobbin rotates in the other direction, a tip 82a of the cam 46 in the waiting orientation is guided by a guiding surface 100, to change the cam 46 from the waiting orientation to the locking orientation. |
