ある。(Prior art and its problems) Generally, in a four-stroke engine, in an overhead camshaft type engine in which a camshaft is mounted on the cylinder head, lubricating oil is supplied by an oil pump during engine operation, and the rotation of the engine is controlled. The sliding parts are lubricated. However, immediately after the engine is started, the lubricating oil from the oil pump cannot reach all of the rotating and sliding parts of the engine, resulting in oil shortage, which can cause scratches, especially on the cam peripheral surface of the camshaft.

受け１１を設ける。 In the case of a V-type engine as shown in FIG. 1, a cylinder 1 and a cylinder head 2 are mounted on a crankcase 3 in a substantially inclined position. Camshaft 4 is attached to cylinder head 2.
is rotatably mounted on a shaft, and as the camshaft 4 rotates, a cam 5 provided on the camshaft 4 pushes open a valve 8 against a valve spring 7 via a rocker arm 6. The valve 8 is slidably inserted into the spring seat 9. However, this invention is a spring seat 9
An arm portion 10 is integrally connected to the outer periphery of the camshaft 4 by press-fitting or the like and protrudes upward, and an oil receiver 11 facing the lower side of the cam 5 of the camshaft 4 is provided at the tip of the arm portion 10.

のビス等の部品も不要となる。 Next, the operation of the present invention will be explained. When the engine is stopped while it is running, the lubricating oil that has adhered to the camshaft 4, cam 5, etc. falls and the oil pan 1.
It accumulates within 1. When the engine is restarted and the camshaft 4 starts rotating, the cam 5 also rotates and the tip of the cam 5 enters the oil receiver 11.
The lubricating oil in the oil receiver 11 adheres to the cam 5, so that the cam can be lubricated from the initial stage of engine startup, and the circumferential surface of the cam 5 is prevented from being scratched due to lack of oil. Furthermore, since the oil pump also starts rotating when the engine starts, lubricating oil will be sent to the camshaft 4 after a short period of time after the engine has started, so the lubricating oil will be received by the oil receiver 11 and lubricated. Oil accumulates in the oil receiver 11. The arm portion 10 provided with the oil receiver 11 is integrally connected to the spring seat 9 by press fitting or the like, and the valve seat 9 is pressed against the cylinder head 2 by the valve spring 7 and does not come off. Therefore, there is no need for parts such as screws for fastening the oil receiver to the cylinder head.
