本考案は一対のカムシヤフトの中間に位置して
シリンダヘツドにカム駆動のアイドルギヤシヤフ
トを固定するようにしたカム駆動アイドルギヤシ
ヤフトの固定装置に関する。DETAILED DESCRIPTION OF THE INVENTION The present invention relates to a fixing device for a cam-driven idle gear shaft, which is located between a pair of camshafts and fixes the cam-driven idle gear shaft to a cylinder head.
この種固定装置においてはアイドルギヤシヤフ
トに別の止めボルトやピン、クリツプ等を係合さ
せているが、かくするときは固定部材が多くなり
その取付けに困難を来たす不都合が存した。 In this type of fixing device, a separate fixing bolt, pin, clip, etc. is engaged with the idle gear shaft, but when doing so, there is a problem that the number of fixing members increases, making it difficult to attach them.
本考案はかヽる不都合を改良することを目的と

させたことを特徴とする。 The present invention aims to improve this inconvenience, and includes a cam-driven idler which is located between a pair of camshafts 1 and 2 and has a cam-driven idler gear shaft 9 fixed to the cylinder head 10. The gear shaft fixing device is characterized in that a mounting bolt 12 for attaching a cylinder head 10 and a cylinder 11 to the idle gear shaft 9 is engaged.

態で固定されている。 The drawing shows a pair of intake camshaft 1 and exhaust camshaft 2, each camshaft 1,
It shows a 4-valve engine having a pair of intake valves 3, 3 and a pair of exhaust valves 4, 4, which are opened and closed by a pair of cams 1a, 1a, 2a, 2a provided in the engine 2,
Each camshaft 1, 2 is driven by an idle gear 7 that meshes with gears 5, 6 provided respectively, and a chain-driven sprocket 8 integrated with the gear 7, and an idle gear shaft 9 that pivotally supports the idle gear 7. is supported by the cylinder head 10, and the cylinder head 10 and cylinder 1 are attached to the shaft rod.
A mounting bolt 12 for attaching the shaft 9 to the shaft 9 is passed through and engaged with the shaft 9 to prevent the shaft 9 from rotating and coming off.

The engagement with the bolt 12 does not necessarily involve engaging the bolt 12 through a through hole provided in the idle gear shaft 9 as shown in the figure, but by engaging the outer periphery of the bolt 12 with a notched groove provided on the outer periphery of the idle gear shaft 9. You can do it like this. 13 in the figure is the Rotzker arm.
14 indicates a sub-locker arm.

有する。 In this way, according to the present invention, the idle gear shaft 9 fixed to the cylinder head 10 is engaged with the mounting bolt 12 for attaching the cylinder head 10 and the cylinder 11, so that the shaft 9 is prevented from rotating. This has the effect that the fixation can be made much easier than in the conventional example described above, in which a separate fixing bolt, pin, clip, etc. is engaged with the fixing bolt.
