To provide a lock device for a bicycle that can perform locking and unlocking operations smoothly if the locking and unlocking operations are repeated for a long period of time, and avoids the situation where a latch does not return into a lock case in the time of unlocking.SOLUTION: The lock device for a bicycle is provided for a bicycle wheel. The inside of the lock device is provided with an arc-shaped latch 11 and an arc-shaped storage space 12 that can store the latch 11, and the lock device has an open part 13. The lock device includes a lock case in which openings 12a in the storage space 12 are disposed so as to face each other through the open part 13, and a tension spring 19, one end of which is attached to a rear end 11a of the latch 11, and that biases the latch 11 in a direction where the latch 11 is stored in the storage space 12. A low friction member 30 that has a coefficient of friction lower than iron is provided at a contact part between the lock case and the latch 11.SELECTED DRAWING: Figure 9
