Abstract:
In an assembling structure of an actuator part of a chemical liquid valve, a cover is formed with a protrusion extending in a radial direction of a valve element, and a cylinder is formed with an engagement part engageable with the protrusion. A cover is placed to hold a spring in a compressed state in the cylinder and make a cap part cover an opening of the cylinder. The protrusion and the engagement part are engaged with each other to integrally connect the cylinder and the cover without separating from each other.
