In the rotor, a plurality of grooves with which a plurality of ribs protruding toward an outer periphery of a needle case are engaged are provided at predetermined intervals. When a needle mounting part of the medicine injection device is inserted in the opening, the rotor provided below the opening rotates, and thereby, an injection needle can be attached/detached with respect to the needle mounting part of the medicine injection device, and safety becomes extremely high.</p> |
