The present invention relates to an ejector assembly and a vacuum pump. The ejector assembly includes a cylindrical vacuum ejector and a support part for supporting both ends of the ejector. The support part includes a first support portion having a supply line extending from a hole, in which an end of a supply port side of the ejector is seated, to the outside, and a second support portion having a discharge line extending from a hole, in which an end of a discharge port side of the ejector is seated, to the outside. The opposite outer surfaces of the first and second support portions are brought into contact with an inner wall of a pipe member additionally provided. A space communicating with a through-hole is formed between both support portions. In the vacuum pump using the ejector assembly, the pipe member is a housing, and the space is a vacuum chamber formed in the housing. |
