Japanese Patent JP2015163805
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide an assembled camshaft 10 which can rigidly join a cam piece 14 to a shaft 12.SOLUTION: A cam piece 14 partitions an insertion hole of a shaft 12 by internal peripheral faces 14b, 14c. The internal peripheral face 14b is formed so that a diameter of the insertion hole becomes large as progressing toward the outside of the insertion hole. A ring-shaped member 16 is inserted between the shaft 12 and the internal peripheral face 14b. A male screw part 14d is formed at a side of an external peripheral face corresponding to the internal peripheral face 14b. Then, a bearing nut 18 is fastened to the male screw part 14d. The bearing nut 18 contacts with an end part of the ring-shaped member 16, and the ring-shaped member 16 is pushed to the internal peripheral face 14c side by the fastening of the bearing nut 18 to the cam piece 14. As the bearing nut 18 is fastened to the cam piece 14, a joining force between the shaft 12 and the cam piece 14 is increased.
