損われるなどの欠点があった。For example, a motorcycle equipped with a conventional electronic fuel injection device using a method similar to the mounting device shown in Japanese Patent Application Laid-open No. 55-799, has a mounting device installed for each cylinder as shown in FIGS. 1 and 2. Each throttle body 1 was connected by a connecting bracket 4, and the fuel injector 2 installed on each throttle body 1 was installed individually on each throttle body 1 using a bracket 3. As the number increased, product assembly time became longer, and the appearance of the product deteriorated, among other disadvantages.

とした。A conventional motorcycle equipped with an electronic fuel injection system requires a connecting bracket for each cylinder and a bracket for mounting a fuel injection valve for each throttle body.
以上のことから、部品数の低減を計る目的により、２種
類のブラケットの各機能を持たせた一体型連結ブラケッ
トとした。Based on the above, in order to reduce the number of parts, we created an integrated connecting bracket that has the functions of two types of brackets.

外観性の向上が得られた。By reducing the number of parts, product assembly time is reduced,
Improved appearance was obtained.
以下、本考案の一実施例を第３図、第４図により説明す
る。An embodiment of the present invention will be described below with reference to FIGS. 3 and 4.
スロットルボディ１は、各気筒毎に設けていることから
個々のスロットルボディ１を連結する必要がある。Since the throttle body 1 is provided for each cylinder, it is necessary to connect the individual throttle bodies 1.
さらに、各スロットルボデイ１毎に装着される燃料噴射
弁２を吸気通路内に燃料が噴射するように装着する必要
がある。Furthermore, it is necessary to install the fuel injection valve 2 for each throttle body 1 so that fuel is injected into the intake passage.
従来は、各スロットルボディ１を連結する連結ブラケッ
トと各スロットルボディ毎に装着される燃料噴射弁２を
取付ける取付はブラケットの２種類のブラケットを用い
ていた。Conventionally, two types of brackets have been used: a connecting bracket for connecting each throttle body 1 and a bracket for attaching the fuel injection valve 2 mounted to each throttle body.

、部品数が低減されるとともに、製品組立時間の低減、
同一平面上により連結固定するために外観性がさらに向
上する効果がある。According to this embodiment, the connection brackets that connect the throttle bodies 1 and the fuel injection valves 2 are installed on the same plane, so that the connection brackets that have the function of connecting each other and the installation of the fuel injection valves 2 are installed in the same plane. The integrated connecting bracket 5 has the functions of two types of brackets, which reduces the number of parts and reduces product assembly time.
Since they are connected and fixed on the same plane, the appearance is further improved.
