The lock mechanism 4 includes a locking base 41, a pawl 42, a pawl spring 43, and a lock gear 44. The pawl 42 includes a first restraint portion 42a that restrains movement of the pawl 42 in one rotating direction of the spool 2 while being located inside an outer periphery of the locking base 41, and a second restraint portion 42b that restrains the movement of the pawl 42 in an opposite rotating direction of the spool 2 while the movement is retrained by the first restraint portion 42a.
