A culture container linkage device according to the present invention is provided with: a first actuator which causes a needle 32 to advance and retract; an actuator-holding part which holds the first actuator and which is rotatably provided to a frame; a second actuator; and a washing part which washes the needle. Among them, the second actuator rotates the needle via the actuator-holding part. The needle can be positioned, by the second actuator, at a container-facing position where the needle faces a culture container, and at a washing-facing position where the needle faces the washing part.
