PROBLEM TO BE SOLVED: To fit a steering wheel to a shaft from the outside of a hub by providing a lock member provided between the hub of the steering wheel and the shaft movably between the lock position where the lock member is coupled with a peripheral groove at one end of the shaft and the release position where it can be extracted from the hub. SOLUTION: A cylindrical opening 12 is formed in an extension section 10 formed on the hub of a steering wheel, and a slot 14 is formed on one side facing the opening 12. A hole 16 is formed on the extension section 10 while crossing the slot 14, and a bolt 18 is rotatably inserted into the hole 16. A cam 22 is fitted to the shank portion of the bolt 18 to be rotated together as a lock member coupled with a peripheral groove 32 and connecting or fixing a shaft 5 and the hub so that the shaft 5 is not moved in the vertical axial direction. When the cam 22 is to be unlocked, it may be merely moved to the release position via the bolt 18, and the wheel can be easily removed from the shaft 5 in this state. |
