本考案はカム軸をシリンダヘツドに取付けるよ
うにしたカム軸取付装置に関する。[Detailed Description of the Invention] The present invention relates to a camshaft mounting device for mounting a camshaft to a cylinder head.
この種装置においては、カム軸のスラスト荷重
が軸受部に加わらないようにするためカム軸には
スラスト受けが設けられるが、このスラスト受け
は例えば、カム軸に突設した環状鍔部と該鍔部が
係合するようにヘツドとヘツドカバとに凹設した
凹溝とをもつて形成されているためその加工が困
難である等の不都合を有していた。 In this type of device, the camshaft is provided with a thrust receiver in order to prevent the thrust load of the camshaft from being applied to the bearing. Since the head and the head cover are formed with a recessed groove so that the parts engage with each other, there are disadvantages such as difficulty in machining the head.

たことを特徴とする。 The present invention is aimed at improving such inconveniences, and includes a camshaft mounting device in which a camshaft 1 is mounted on a cylinder head 2, in which the camshaft 1 is supported on the cylinder head 2. A pin 3 is provided that is located directly below the camshaft 1 in the approximate center between the bearings 6, 6 at both ends and projects upward, and an annular groove 4 that engages with the tip of the pin 3 is provided in the camshaft 1. It is characterized by

２に突設するピン３とカム軸１に凹設される環状
凹溝４とはその加工を容易にして正確に形成でき
る等の効果を有する。 According to the present invention, the cylinder head 2 is provided with a pin 3 that protrudes upward and is located directly below the camshaft 1 in the approximate center between the bearings 6, 6 at both ends that support the camshaft 1. Since the camshaft 1 is provided with an annular groove 4 that engages with the tip of the camshaft 3, the camshaft 1 only needs to be supported at both ends by bearings 6, 6, and its movement in the thrust direction is controlled by the annular groove 4. The camshaft 1 is regulated by the engaging pin 3 to simplify the bearing means of the camshaft 1, and the camshaft 1 is regulated by the bearings 6, 6 at both ends of the camshaft 1.
Since the camshaft 1 is supported by a pin 3 at approximately the center of the camshaft 1, it is possible to effectively prevent the camshaft 1 from bending. This has advantages such as easy and accurate formation.
