Benefits of technology

[0012]Various aspects of the present invention are directed to providing an end piece for a camshaft, configured for having an advantage in terms of cost and no issues in a joint portion with a camshaft since the end piece is not made entirely of steel, and a method of manufacturing the same, configured for more effectively performing a forming process.

Problems solved by technology

However, it is difficult to form the end piece by powder metallurgy due to the long length of the end piece, and the joint portions between the end piece and the camshaft need to use the same material to bond the end piece to the camshaft by brazing or friction welding.
