The objective of the invention is to achieve a general-purpose relief valve which can be used irrespective of the diameter or thread shape of an associated relief conduit and whose relief pressure can be easily adjusted. A relief valve includes a valving element, a spring device for seating the valving element onto a valve seat so as to close a flow channel, and a connecting portion which is connected to a relief conduit, wherein the valving element is released from the valve seat upon an internal pressure of the relief conduit exceeding a valve-closing force applied by the spring device, wherein a cylindrical valve body which includes the valve seat, the valving element and the spring device, and a retainer body which is connected to the relief conduit are formed as separate members, and the cylindrical valve body and the retainer body are connected to each other.
