PROBLEMS TO BE SOLVED BY PRIOR ART AND DEVICE The purpose of the present invention is to attach a plurality of blocks, each having a compressed air flow passage formed therein and a solenoid valve attached thereto, to each other by joining them to a mounting member. The applicant of the present application, as described in Japanese Utility Model Laid-Open No. 60-180802, locks a plurality of blocks on a mounting rail by clip means and slides the blocks along the length direction thereof. , Proposed a connection structure in which the flow paths of adjacent blocks are connected by fitting the unevenness of their openings, and these blocks are sandwiched by two end blocks from both sides and attached to a mounting rail. The structure is
Since the adjacent blocks are not coupled to each other, it is necessary to firmly fix the two end blocks to the mounting rail by using a troublesome clamp means.
When removing the intermediate block, at least one end block needs to be released from the fixing to the mounting rail by loosening its clamp, and a means for easily performing the mounting and dismounting work has been desired. .

Means for Solving Problems As a means for solving the above problems, the solenoid valve manifold of the present invention is provided with a fitting hole formed on the joining surface of adjacent blocks so as to be aligned with each other by joining the blocks. A connecting portion that connects the connecting pieces to each other by inserting a connecting piece protruding from the block and inserting it from a slit formed on the outer periphery of the block and penetrating the fitting hole. Adjacent blocks are coupled with each other by a coupling member that includes a latching portion that latches, and an engaging portion that engages with a locking edge formed on the block by elastic deformation to prevent the block from being pulled out, Moreover, it is configured to be hooked on the mounting member.

Advantageous Effects and Effects of the Invention The present invention has the above-described configuration, and when mounting the blocks, each block is locked to the mounting member in the mounting posture and the adjacent blocks are bonded to each other, and the coupling member is inserted from the slit. Then, the connecting part connects the connecting pieces of the adjacent blocks and the hooking part hooks on the mounting member, so that the adjacent blocks are connected and each block is hooked on the mounting member at the same time. At the same time, the engaging portion is engaged with the locking edge of the block, so that the coupling member is held so as not to be removed from the block,
All blocks are integrally connected and attached to a mounting member in a non-separable manner, and when removing the block, when the coupling member is removed from the block by disengaging the engaging portion from the locking edge, Since the coupling and the hooking to the mounting member are released at the same time, the work of mounting and dismounting can be performed easily and in a short time simply by inserting the coupling member into the slit or extracting it from the slit. Further, it is sufficient to use one end block for immovably fixing to the mounting member, and since only one connecting member, which is one less than the number of blocks, is required as a mounting component, the conventional As described above, the number of parts is smaller than the case where two end blocks are required in addition to the same number of clip means as the blocks for locking to the mounting rail. It is effective that it is possible to reduce cost.
