Claims

[Claims for Utility Model Registration] A drive shaft equipped with a variable intake control valve for substantially changing the intake pipe length of an engine, the drive shaft having two drive shafts, a first drive shaft and a second drive shaft. A first connecting member is attached to the tip of the first drive shaft, and a second connecting member is attached to the tip of the second drive shaft,
The second connecting member has an annular shape, the first connecting member has a substantially cylindrical shape, the first connecting member is fitted into the second connecting member, and the first connecting member is fitted into the second connecting member. An adjustment bolt is screwed onto the connection member, the adjustment bolt extends in the radial direction of the first connection member, and the adjustment bolt has a head for engaging a tool, a body, a screw portion screwed onto the first connecting member, and the body portion of the adjustment bolt is aligned with a through hole drilled in the second connecting member. In the drive shaft of the valve, a center line extending in the axial direction through the center of the body of the adjustment bolt is aligned with a center line extending in the axial direction through the centers of the head and threaded portion of the adjustment bolt. A drive shaft of a variable intake control valve characterized by being eccentric with respect to the drive shaft.
