That is, the positioning bracket 21 is not disposed at the mounting position with respect to the rail 11.

  As shown in FIG. 7, in the state where the second locking portion 32b is not disposed opposite to the surface of the second projecting piece 11e on the second standing portion 11c side, the axis C1 of each through-hole 45 and each screw 23 axis C2 does not coincide. Therefore, even if the tool 25 is passed through the through hole 45 and the screw 23 is tightened, the tool 25 is inclined with respect to the axis C2 of the screw 23, and the screw 23 is difficult to tighten. Accordingly, the screw 23 is difficult to tighten in a state where the second locking portion 32b is not disposed opposite to the surface of the second projecting piece 11e on the second standing portion 11c side.

  As shown in FIG. 3, the operating member 50 is slid in order to slide the positioning member 21 in the direction in which the first continuous portion 31a is separated from the first projecting piece 11d. As a result, the first locking portion 31b is disposed opposite to the surface of the first protruding piece 11d on the first standing portion 11b side, and the entire second locking portion 32b is the second protruding piece 11e. 2 Positioned opposite to the surface on the upright portion 11 c side, the positioning bracket 21 is disposed at the mounting position with respect to the rail 11. At this time, the locking portion 51 is locked to the locked portion 47, and the positioning fitting 21 is maintained at the mounting position.

  As shown in FIGS. 3 and 8, when the positioning fitting 21 is disposed at the mounting position with respect to the rail 11, the axis C <b> 1 of each through-hole 45 and the axis C <b> 2 of each screw 23 coincide. As a result, the tool 25 can be passed through each through-hole 45 and each screw 23 can be tightened. When each screw 23 is tightened, the positioning fitting 21 moves in a direction in which the first locking portion 31b and the second locking portion 32b are directed toward the first protruding piece 11d and the second protruding piece 11e. The first projecting piece 11d is sandwiched between the press contact portion 26b and the first locking portion 31b by the thrust of each screw 23 accompanying tightening of each screw 23, and the second projecting piece 11e is sandwiched between the press contact portion 26b and the second contact portion 26b. It is sandwiched between the locking portion 32b. Thereby, the positioning fitting 21 is attached to the rail 11 via the first protruding piece 11d and the second protruding piece 11e, and the position of the electromagnetic valve manifold 10 along the longitudinal direction of the rail 11 is positioned by the positioning fitting 21. The Further, the end block 12 is attached to the rail 11 via the interposition member 26. Therefore, the solenoid valve manifold 10 is attached to the rail 11 via the interposition member 26, and the solenoid valve manifold 10 is prevented from falling off the rail 11.

In the above embodiment, the following effects can be obtained.
(1) The positioning device 20 includes a cover member 40 having a through hole 45 through which a tool 25 used when the screw 23 is tightened passes. The cover member 40 is located at a position where the axial center C1 of the through hole 45 and the axial center C2 of the screw 23 coincide with each other when the positioning bracket 21 is disposed at the mounting position with respect to the rail 11. Has been placed. According to this, when the axial center C1 of the through-hole 45 and the axial center C2 of the screw 23 coincide, the tool 25 can be passed through the through-hole 45 and the screw 23 can be tightened. On the other hand, when the positioning bracket 21 is not disposed at the mounting position with respect to the rail 11, the axis C1 of each through hole 45 and the axis C2 of each screw 23 do not coincide. Therefore, even if the tool 25 is passed through the through hole 45 and the screw 23 is tightened, the tool 25 is inclined with respect to the axis C2 of the screw 23, and the screw 23 is difficult to tighten. Therefore, since the screw 23 can be tightened only when the positioning bracket 21 is disposed at the mounting position with respect to the rail 11, the stability of the mounting state of the positioning bracket 21 with respect to the rail 11 can be improved. Can be planned.

  (2) The positioning fitting 21 is provided with an engaging protrusion 22f, and the cover member 40 is provided with an operation member 50 that engages with the engaging protrusion 22f so as to be slidable with respect to the cover member 40. According to this, when the operation member 50 is slid, the positioning bracket 21 can also be slid integrally, so that the positioning bracket 21 can be slid from the outside of the cover member 40, and the positioning bracket 21 is operated. It is possible to improve the performance.

  (3) The operation member 50 is provided with a locking portion 51. The cover member 40 is provided with a locked portion 47 that is locked with the locking portion 51 when the positioning bracket 21 is disposed at the mounting position with respect to the rail 11. According to this, the positioning fitting 21 can be maintained at the mounting position by the locking of the locking portion 51 and the locked portion 47, and the tightening operation of the screw 23 can be facilitated.

  (4) The inner wall surface 45a forming the through hole 45 in the cover member 40 is cylindrical. According to this, for example, the tool 25 can be easily guided along the axis C <b> 1 of the through-hole 45 as compared with the case where the inner wall surface 45 a forming the through-hole 45 is an elliptic cylinder. As a result, the screw 23 can be easily tightened.

  (5) The interposition member 26 having the press contact portion 26 b is attached to the end block 12. According to this, since the end block 12 is attached to the rail 11 via the interposition member 26, the electromagnetic valve manifold 10 is attached to the rail 11 via the interposition member 26, and the electromagnetic valve manifold 10 is separated from the rail 11. Dropout can be prevented.
