The present invention is a discharge device for liquid substances that is provided with at least a valve main body (6) that has: a syringe accommodating space (93) that accommodates a valve seat assembly (3), and a syringe (1)/functional cartridge in which a needle (4) is installed, and that houses driven parts (7, 8) which are driven by an actuator (5) and are magnetically coupled with the needle; and a positioning member (14) which impels the syringe (1) towards a fixed position. This configuration enables simple removal of only the valve seat assembly and the syringe/functional cartridge containing the needle from the valve main body. |
