Abstract
A joint includes a first block, a second block, and a single pipe section connecting the first block and the second block. The first block, the second block, and the single pipe have a first gas passage and a second gas passage inside therein. The first gas passage is formed so that a first port which opens at an outer surface of the first block, the single pipe section, and a second port which opens at an outer surface of the second block communicate with each other. The second gas passage is formed so that a third port and a fourth port which open at the outer surface of the second block communicate with each other. The second port is disposed between the third port and the fourth port.
