Abstract

PURPOSE: To facilitate removal of crankshaft of a bicycle having the end of a tapered crankshaft fitted to the end of a pedal crank by forming a crankshaft fitting hole and a screw hole for removing the crankshaft concentrically on the crank. CONSTITUTION: The end 2 of a pedal crankshaft 1 is formed so that its cross section may be almost square and close to a truncated pyramid shape towards the free end. A pedal crank 3 is formed with a hole 4 corresponding to the cross section of the pedal crankshaft 1 end 2 and a through screw hole 5 coaxially to the hole 4. The screw 5 has run through it the shaft of a head screw 7 screwed to the screw hole 6 on the crankshaft 1 and the crankshaft 1 is connected to the crank 3 by tightening the screw 7. To disconnect the connection of the two cranks 1, 3, the screw 7 is removed, after which a standard screw 14 is screwed into the scew hole 5 and the crankshaft 1 is pushed out from the crank 3 by screwing the screw 14.
