本考案はオーバーヘツドバルブ式エンジンのバ
ルブ頭部へ潤滑油を供給する装置に関するもので
ある。[Detailed Description of the Invention] (Industrial Application Field) The present invention relates to a device for supplying lubricating oil to the valve head of an overhead valve type engine.

耗や加熱を防止するために十分に潤滑がなされる
ことが必要である。(Problems to be solved by conventional techniques and ideas) An intake valve that supplies fuel into the cylinder and an exhaust valve that discharges exhaust gas from the cylinder to the outside are installed at the top of the engine of a motorcycle, etc. The intake and exhaust valves are opened and closed by a camshaft that rotates in accordance with the cycle timing of the engine and a rocker arm that swings up and down by the camshaft. The contact areas between the rocker arm and the intake/exhaust valve head must be sufficiently lubricated to prevent wear and heat.

一点を中心に上下にスイングするロツカアーム内
の油路に潤滑油を供給することも装置の複雑化の
原因となつていた。 Conventionally, this part has been lubricated by forcibly sending lubricating oil from an oil pump to the intake/exhaust valve head via an oil passage formed in the rocker arm. However, providing oil passages that open to the intake and exhaust valve heads in a rocker arm with a relatively complicated shape that is operated by a camshaft complicates the structure of the rocker arm, takes time and effort to manufacture, and increases costs. I was getting used to it. Furthermore, supplying lubricating oil to the oil passage in the rocker arm, which swings up and down around a single point, also makes the device more complicated.
本考案は以上の如き問題点を解決すべくなされ

設けたことである。(Means for Solving the Problems) A means for solving the above problems is to install a camshaft holder in an overhead valve type engine that is equipped with a camshaft on the cylinder head that controls the opening and closing of the valve. A lubrication guide for supplying lubricating oil to the valve head is provided on the top surface, and the lubrication guide is fixed to the camshaft holder with a mounting bolt that is shared with the camshaft holder, and the lubrication guide is installed in the mounting bolt hole of the camshaft holder. An oil supply hole is provided that communicates the oil passage and introduces lubricating oil into the oil supply guide through the mounting bolt hole.
