されるに至っている。2. Description of the Related Art As a means for branching a fluid such as a liquid or a gas from a single main supply pipe, a branch pipe is screwed to the side surface of the main supply pipe as disclosed in Japanese Utility Model Laid-Open No. 2-40191. A T-type branch connection structure in which the branch portion is fixed and reinforced with a frame from the outside is generally widely used. However, since the work of connecting the branch pipe to the mainstream pipe is troublesome, it is necessary to use the branch pipe in advance during piping work. When the necessity is set, for example, JP-A-63-280999 or JP-A-3
As described in Japanese Patent Publication No. 149492, a method of preliminarily inserting a fluid branching tool (multiple pipe joint) in the main supply pipe and connecting a branch pipe to the branch port to divide the fluid is preferably used. Has been done.

きるようになした流体ブロックが提案されている。However, the fluid branching device as described above has a disadvantage in that the number of branch pipes is specified and the number of branch pipes cannot be increased or decreased. As a means for improving this disadvantage, JP-A-63-29 is known.
As disclosed in Japanese Patent No. 7897, there has been proposed a fluid block in which a desired number of blocks each having a central flow passage and a change flow passage can be connected to be inserted in a main supply pipe.

ければならない。However, in the above conventional fluid block having the central flow passage and the change flow passage, it is possible to equip the main supply pipe with a desired number of branch flow passages by connecting the blocks. Although it has the advantage of being able to do so, on the other hand, once a plurality of blocks have been connected and fixed, the direction of the branch flow passage cannot be changed arbitrarily. For example, four blocks are connected and After the branch channels of one block are fixed in the lateral direction and the remaining one branch channel is fixed in the upward direction, even if it is necessary to change the direction of the branch channels, once the blocks are connected together. You have to work to release the connection and re-connect.
