PROBLEM TO BE SOLVED: To improve sealability and assemblability of a connector member for connecting a pipeline block.SOLUTION: A tubular connector member 1 is used for a pipeline connection structure in which a pair of pipeline blocks with pipelines inside are opposed to each other and the pipelines of the respective pipeline blocks are connected to each other. The connector member 1 is formed into a straight pipe shape by injection molding synthetic resin, and seal parts 11, 11 inserted in the respective pipeline blocks are provided at both ends of the connector member. Plural injection molding gate marks 12, 12 are provided at a center part in a longitudinal direction of the connector member, and at a symmetrical position relative to a center axis of the connector member. |
