Being the injector which equips the intermediate sliding valve and the plunger sliding valve and the said sliding valve which contact the liquid medicine which is loaded inside the injector directly, influence to the said liquid medicine from the first offers the sliding valve and the injector which do not have the influence by the said liquid medicine. The intermediate sliding valve 10 which is equipped inside the injection tube, 1st elastic body it consists of with 2nd elastic body 14 of the abbreviation cylindrical condition where is connected with base 13c of one side of 13 of abbreviation cylindrical condition and the said 1st elastic body, plastic film 15 is laminated by the side part which is continued from other base 13of a 1st elastic body 13 and the said base, plastic film 16 being laminated by the side part which is continued from other base 14of a 2nd elastic body 14 and the said base, becomes, 1st elastic body connection of 13 and 2nd elastic body 14, is done by the fact that the annular concave section 18 which was formed to the base and convex section 17 fits. In order the occasion where it is inserted in the injection tube, 1st elastic body for the connection section of 13 and 2nd elastic body 14 not to contact the inner wall of the injection tube, it is formed.
