PROBLEM TO BE SOLVED: To provide a small ratchet part that is superior in handleability to be formed in a small type, returns to an original hexagonal shaft replacing type driver when unnecessary, and is formed as a ratchet driver by adding the ratchet function to an existing hexagonal shaft replacing type driver.SOLUTION: A ratchet ring 2 is rotated, and is set in a rightward idle rotation and leftward idle rotation position and a neutral (fixed) position, and a ratchet claw 15 is engaged with a ratchet claw holding long groove 23 of the ratchet ring 2 and a ratchet bit holder 3 and a gear part 10, and thereby, can be formed as a rightward rotation and leftward rotation ratchet driver. |
