  • Air intake apparatus for internal combustion engine
    Patent number: 6520138
    Abstract: A rotating shaft and a drive shaft are used in an air intake apparatus for an internal combustion engine. At one end portion of the rotating shaft and the drive shaft a sphere portion and a projection portion are formed, and another end portion of the rotating shaft and the drive shaft a cup portion and a faucet portion are formed. The sphere portion is inserted to the cup portion and further the projection portion is engaged with the faucet portion, thereby a universal joint is formed. Since a connection structure between the rotating shaft and the drive shaft is constituted with few component elements, a cost reduction in the air intake apparatus for the internal combustion engine can be improved.
