For example, when an actuator such as an air cylinder is driven by a solenoid valve, it is necessary to connect these solenoid valve and the actuator by piping. When a plurality of actuators are driven, a plurality of solenoid valves corresponding to them are used, so that the number of pipes naturally increases. When connecting the solenoid valve and actuator with piping in this way, normally, the solenoid valve and actuator are each fixed in place and then pipe fittings are attached to their ports to connect the piping. However, since it is necessary to carry out the steps from the fitting of the pipe joint to the connection of the pipes one by one separately and in order, the number of man-hours increases and the work is very troublesome.

Such a fixing mechanism is desirably provided at intervals such that every three or four pipe joints 6 are fixed, but may be provided so as to fix all the pipe joints 6. Alternatively, the pipe joint 7 may be fixed by providing the clip insertion hole 35 and the clip 37 also in the air supply / exhaust block 13.
[0032]
Since the fluid pressure device 100A has such a configuration, pipes 23 from actuators such as air cylinders are connected in advance to the pipe joints 6 and 7 in the pipe joint assembly 2A. After the actuator and the fluid pressure device 1 are installed at predetermined positions, the port connection portions 19 of the pipe joints 6 and 7 in the pipe joint assembly 2A are inserted into the corresponding ports of the fluid pressure device 1 and connected by the clips 37. By fixing to the state, the pipes 23 from the respective actuators can be collectively connected to the respective ports 3A, 3B, 4 and 5 of the fluid pressure device 1. As a result, the connection work of the plurality of pipes 23 can be performed easily and accurately without causing erroneous connection.
[0033]
FIG. 6 shows a second embodiment of the fluid pressure device. The fluid pressure device 100B of this second embodiment is slightly different from the tube joint assembly 2A of the first embodiment in the configuration of the tube joint assembly 2B. That is, in this pipe joint assembly 2B, as can be seen from FIGS. 7 and 8, the portions 18a fitted into the holding holes 29 and 30 at the tips of the body portions 18 of the pipe joints 6 and 7 have a polygonal shape.

It has become. However, the openings 40 and 40 are made into normal holes that are not screw holes, and the pipe connection ports of the pipe joints 6 and 7 are formed in the screw holes, or the pipes are plugged in like the pipe joints of the first embodiment. It may be configured to be connectable, and a pipe may be connected to the connection port through the openings 40 and 40.
[0042]
Since the configuration of the third embodiment other than the above is substantially the same as that of the first embodiment, the same reference numerals as those of the first embodiment are assigned to the same identical components, and the description thereof is omitted.
[0043]
In each of the above-described embodiments, the split manifold block 11 is used for the fluid pressure device 1, but a single manifold block on which a plurality of electromagnetic valves 10 can be simultaneously mounted can also be used. In this case, a plurality of sets of output ports 3A and 3B communicating with each electromagnetic valve 10 are formed in this manifold block.
