Abstract
An arm direction changeover valve () is provided in an arm block (). A first pilot check valve () is provided in a first block (). A second pilot check valve () is provided in a second block (). The three blocks, i.e., the arm block (), the first block (), and the second block () are arranged side by side. The first block () and the second block () are arranged to be contiguous to each other. Accordingly, an increase in size can be prevented even if a float mechanism and a multi-direction changeover valve are formed integrally with each other.
