本考案は、従来の気（？器針弁にバネを介してフロート
アームのアームベロ二を係合させる機構の改良をなした
新規なる轡構を蝉供するものである。[Detailed Description of the Invention] The present invention provides a new mechanism which is an improvement on the conventional mechanism for engaging the arm tongue of the float arm with the needle valve via a spring.

一部２との間にバネ３を配した形式の針弁装置Ａが採用
される場合が多くなっている。In a needle valve device used in a carburetor, which operates synchronously with Jiro 2a to open and close the fuel chamber inlet 7, the needle valve 1 is operated in synchronization with the fuel chamber inlet 7. Due to the effects of vibration, etc., problems such as wear and damage of the valve seat 5 occur, and in order to minimize these problems, a gap between the needle valve 1 and the arm tongue part 2 of the float arm 2' is installed. A needle valve device A in which a spring 3 is disposed on the needle valve device A is increasingly being adopted.

（役目）を果さない等の不具合を発生させている。(See Fig. 4) Here, in the mechanism in which the spring 3 is provided between the needle valve 1 of the carburetor and the arm tongue part 2 of the float arm 2', the lower end 3a of the spring 3 immediately hits the arm tongue part 2. It is in a seated state, and part of the arm tongue 2
When the spring 3 and the arm bellow part 2 are attached to the needle valve 1 (assembled), there is a danger that the lower end 3a of the spring will not sit properly on the arm bellow part 2 and will be attached in a tilted state. In some cases, this causes problems such as the spring not fulfilling its original function (role).

きる。In order to eliminate such problems, the present invention provides the first and third
As shown in the figure, a spring 3 is disposed between the needle valve 1 of the carburetor and the arm tongue part 2 of the float arm 2', and under the spring i3
A clip 4 is installed between the large-diameter portion 1a at the lower part of the needle valve, and an arm tongue portion 2 is inserted between the large-diameter portion 1a and the clip 4 to intervene. With this configuration, the lower end 3a of the spring does not immediately sit on the arm tongue portion 2, and the spring 3 seated on the clip 4 resists the action force of the spring 3, and the lower end 3a of the spring is not seated immediately on the arm tongue portion 2. Since the arm bellow part 2 is inserted and interposed between the clip 4 and the large-diameter portion 1a at the lower part of the needle valve, the spring 3 is securely seated without being installed (assembled) in an inclined state, so that it can be removed. The spring can perform its original role without any problems.
従って気化器の針弁装置として円滑な作動状態が得られ
る。Therefore, a smooth operating condition can be obtained as the needle valve device of the carburetor.
