種々に変形可能であり、例えば、点火コイル２０、２１
を実施例のようにボルト・ナットによる締結構造とせ
ず、予めエアクリーナケース１５へ嵌合部等を形成し、
これにはめ込み等で取付けるようにしてもよい。The invention of the present application is not limited to the above-described embodiment, but can be modified in various ways. For example, the ignition coils 20 and 21 can be modified.
Instead of the fastening structure using bolts and nuts as in the embodiment, the fitting portion and the like are formed in the air cleaner case 15 in advance.
You may make it attach by this etc. to this.
【００３３】さらに、燃料噴射弁と組合せて採用する場
合等には、吸気系部品として、Ｖ型配置された両気筒の
吸気通路へ接続する公知の一体的なスロットルボディを
採用でき、この場合にはスロットルボデイの前後等、対
応する気筒へ対面する部分に点火コイルを取付けるよう
にする。Further, in the case where it is used in combination with a fuel injection valve, a known integral throttle body connected to the intake passages of both V-shaped cylinders can be adopted as an intake system component. The ignition coil is attached to the portion facing the corresponding cylinder, such as before and after the throttle body.
【００３４】このようにすると、スロットルボディをエ
ンジンの吸気通路に連結する作業でスロットルボディに
小組された点火コイル等の電装品をシリンダヘッド近傍
に取付けて配設できることになり好都合であるととも
に、スロットルボディとエンジンのシリンダヘッドとの
間であれば、燃料噴射弁他に配置されるものが特にな
く、エアクリーナケースよりもさらにシリンダヘッドに
近いので、配線作業もさらに容易になる。With this arrangement, it is convenient to connect the throttle body to the intake passage of the engine so that the electrical components such as the ignition coil, which are assembled into the throttle body, can be mounted near the cylinder head. Between the body and the cylinder head of the engine, there is nothing particularly arranged in the fuel injection valve and the like, and since it is closer to the cylinder head than the air cleaner case, the wiring work becomes easier.
【００３５】また、Ｖ型配設される両気筒の配設方向は
車体の前後方向又は左右方向のいずれでもよく、左右方
向に配設されたものであれば、電装品も吸気系部品の左
右端部側へ取付けられるから、走行風を両気筒間に配置
された吸気系部品の左右両端側へ導くことが容易であ
り、その結果、吸気系部品の左右両端部側へ取付けられ
ている電装品の冷却効率がさらに向上する。The V-shaped cylinders may be arranged either in the front-rear direction or in the left-right direction of the vehicle body. Since it is mounted on the end side, it is easy to guide the traveling wind to the left and right end sides of the intake system parts arranged between both cylinders. The cooling efficiency of the product is further improved.
【００３６】さらにまた、本願発明の対象とする電装品
として例えば、気化器と燃焼室との間へエアクリーナケ
ースからの新気を必要に応じて供給するための電磁弁で
あってもよい。この場合、Ｖ型配設される両気筒の各シ
リンダヘッド部分とエアクリーナケースに取付けた電装
品とを接続する部材は新気供給用のチューブとなるが、
その接続距離を短くすること、組付け作業並びに接続作
業がそれぞれ容易になる等の本願発明における諸効果は
上記実施例同様に期待できる。Furthermore, the electrical component of the present invention may be, for example, a solenoid valve for supplying fresh air from the air cleaner case between the carburetor and the combustion chamber as needed. In this case, a member for connecting the cylinder head portions of both cylinders arranged in the V-shape and the electric components attached to the air cleaner case is a tube for supplying fresh air,
The various effects of the present invention such as shortening the connection distance and facilitating the assembling work and the connecting work can be expected as in the above-described embodiment.
