PROBLEM TO BE SOLVED: To provide a multiple directional selector valve to which an additional directional selector valve can be added while reducing the number of bolts and avoiding leakage of hydraulic oil. SOLUTION: An additional directional selector valve 55 which shares a first unloading passage, a second unloading passage and a tank passage is formed so as to be added, in a fluid-tight state, on an end face of a valve body 50 in the state a cover is removed, through a seal member. The additional directional selector valve 55 is formed into a unitary member by being molded integrally with the cover so that its housing 40 can have a function of the cover. Since the housing 40 is formed into the unitary member by being molded integrally with the cover so as to have the function of the cover, the thickness of the cover is added to the thickness of a housing of the directional selector valve. Accordingly, rigidity of the unitary member increases, and inflexibility against pressing force can be increased.
