固定される針部とからなる。The specific features are a hollow pipe for measuring the sample to be introduced, a sealing member that is fitted to one end of the hollow pipe and constitutes the end face of the pipe, and is threaded to both ends that cover the outside of the hollow pipe. Sleeve, two caps for fixing the seal member and the hollow pipe by using the screw of the sleeve while holding the hollow pipe from both sides of the hollow pipe, and the cap on the end surface of the hollow pipe on the opposite side to the seal member. It consists of a plunger that is inserted into the pipe and a needle that is fixed to the end face of the seal member.
（ホ）作用 本考案は，針を，接着剤を使用せずにシール部材を介し
てバレルに固定するので，高温でも使用可能である。(E) Action The present invention can be used even at high temperature because the needle is fixed to the barrel through the seal member without using an adhesive.
（ヘ）実施例 本考案の実施例を図面に基づいて説明する。(F) Embodiment An embodiment of the present invention will be described with reference to the drawings.
