The inner surface cylindrical portion 116 has elasticity. When no external force is applied to the inner surface cylindrical portion 116, the inner surface cylindrical portion 116 elastically maintains the second shape of fig. 4. When the facing surface distance changing portion 117 is pressed in the-Z direction by an external force, the inner circumferential surface 116a of the inner surface cylindrical portion 116 sandwiches the outer circumferential surface 114c of the rotating portion 114a, and the inner surface cylindrical portion 116 has a first shape.

The fixing member 118 is inserted through the through hole 117b of the facing surface distance changing portion 117 and is screwed to the screw hole 119a of the base portion 119. At this time, the fixing member 118 presses the facing surface distance changing portion 117 in the-Z direction via the washer 118 b. The rotation preventing portion 130 maintains the first shape by screwing the fixing member 118 to the base portion 119.

The base 119 has a slit facing surface 120b at the + Z direction end. The slit opposing surface 120b is a surface extending in a direction parallel to the boundary surface 1 a.

[ second embodiment ]

< rotation blocking part 930 >

Fig. 8 is a perspective view showing a structure of a rotation preventing portion according to a second embodiment of the present invention. In the second embodiment, the structure not shown in fig. 8 is the same as that in the first embodiment. In the second embodiment, the control valve device 1 includes the regulator 914 in place of the regulator 114 of the first embodiment, and includes the rotation preventing portion 930 in place of the rotation preventing portion 130 of the first embodiment. In the second embodiment, the structure alternative to that in the first embodiment is the same as that in the first embodiment unless otherwise specified.

The adjuster 914 has a rotation portion 914 a. The rotating portion 914a has a convex portion 914d protruding radially outward on the outer peripheral surface 914 c. In fig. 8, the convex portion 914d is plural, but may be single. The rotation preventing portion 930 is reversibly deformable to a first shape that prevents rotation of the rotating portion 914a and a second shape that does not prevent rotation of the rotating portion 914 a. The rotation preventing portion 930 includes a plate-like member 918 and a fixing member 919 for fixing the plate-like member 918 to the main body 4. The plate-like member 918 is, for example, a metal flat plate-like member. One end side (+ X direction side) of the plate-like member 918 is flexed in the + Z direction at a flexure point 920a, and flexed in the-X direction at a flexure point 920 d. The other end side (-X direction side) of the plate-like member 918 is bent in the + Z direction at a bending point 920b, and bent in the + X direction at a bending point 920 d. The plate-like member 918 is fixed to the body 4 between the buckling point 920a and the buckling point 920b by a fixing member 919. The fixing member 919 is a bolt.

The other end side (the (-X direction side) of the plate-like member 918 has a claw portion 918 a. One end side (+ X direction side) of the plate-like member 918 is a claw portion 918 b. In fig. 8, the claw portion may be plural, or may be single. The claw portions 918a and 918b are in contact with the outer peripheral surface 914 c. The claw portions 918a and 918b are located on the movement locus of the convex portion 914d in accordance with the rotation of the rotating portion 914 a. Therefore, the movement of the convex portion 914d is stopped by the claw portions 918a and 918b, and in the state shown in fig. 8, the rotation of the rotating portion 914a is stopped by the rotation stopping portion 930. The shape of the claw portions 918a and 918b on the movement locus of the convex portion 914d is the first shape.

When a force for rotating the rotating portion 914a by an external force acts, the plate-like member 918 flexes, and the claw portions 918a and 918b are separated from the moving locus of the convex portion 914d accompanying the rotation of the rotating portion 914 a. Therefore, the rotating portion 914a can rotate. The shape in which the claw portions 918a and 918b are separated from the movement locus of the convex portion 914d is the second shape. The plate-like member 918 is a member having elasticity. In the absence of an external force, the plate-like member 918 returns to the first shape by elasticity.

< Effect/Effect of control valve device 1 >

Next, the operation and effect of the control valve device 1 will be described.

(1) In the utility model of the above embodiment, the angle formed by the boundary surface 1a and the slit opposing surface 120b of the first rotation preventing portion (rotation preventing portion 130) as the rotation preventing portion for the first valve body (electromagnetic valve 100) among the plurality of valve bodies (electromagnetic valves 100, 200, 300, 400, 500, 600, 700, 800) is a first angle, the angle formed by the boundary surface 1a and the slit opposing surface 820b of the second rotation preventing portion (rotation preventing portion 130) as the rotation preventing portion for the second valve body (electromagnetic valve 800) among the plurality of valve bodies is a second angle, and the first angle is different from the second angle. Therefore, since the directions of the fixing operations performed on the rotating portion 114a of the solenoid valve 100 and the rotating portion 814a of the solenoid valve 800 can be made different, the degree of freedom of the arrangement position when the plurality of valve bodies are arranged in the upper body 2 is increased, the valve bodies can be arranged in a narrow space, and the volume and size of the control valve device 1 can be suppressed.

(2) The valve body 110 includes a solenoid 105 that moves the pin 102 in the axial direction by excitation of a coil, and the spool 111 is located on one axial side of the solenoid 105 and is movable in the axial direction in accordance with the movement of the pin 102. Therefore, even in the configuration including the solenoid 105, the directions of the fixing operations performed on the rotating portion 114a of the solenoid valve 100 and the rotating portion 814a of the solenoid valve 800 can be made different, and therefore, the degree of freedom of the arrangement position when the plurality of solenoid valves are arranged in the upper body 2 is increased, and the solenoid valves can be arranged in a narrow space, and the volume and size of the control valve device 1 can be suppressed.

(3) The urging member 113 is a coil spring. Therefore, the spool valve can be biased with a simple structure.

(4) Further, since the fixing members (the fixing members 118 and 818) are bolts and the insertion direction of the bolts of the first solenoid valve (the solenoid valve 100) is different from the insertion direction of the bolts of the second solenoid valve (the solenoid valve 800), the degree of freedom of the insertion direction of the bolts when the plurality of solenoid valves are arranged in the upper body 2 is increased, and the volume and size of the control valve device 1 can be suppressed.

(5) The bolt of the first solenoid valve (solenoid valve 100) is inserted in a direction perpendicular to the boundary surface 1a, and the bolt of the second solenoid valve (solenoid valve 800) is inserted in a direction parallel to the boundary surface 1 a. Therefore, the degree of freedom in the bolt insertion direction when the plurality of solenoid valves are arranged in the vertical direction and the horizontal direction in the upper body 2 is increased, and the volume and size of the control valve device 1 can be suppressed.

(6) The insertion direction of the bolt into the third solenoid valve (solenoid valve 700) is not a direction perpendicular to the boundary surface 1a, nor a direction parallel to the boundary surface 1 a. Therefore, the degree of freedom in the bolt insertion direction when the plurality of solenoid valves are arranged in the upper body 2 in a direction other than the vertical direction and other than the horizontal direction is increased, and the volume and size of the control valve device can be suppressed.

(7) In addition, the position of the first fixing member (fixing member 118) as the fixing member for the first solenoid valve (solenoid valve 100) among the plurality of solenoid valves in the vertical direction with respect to the boundary surface 1a is a first position, the position of the second fixing member (fixing member 818) as the fixing member for the second solenoid valve (solenoid valve 800) among the plurality of solenoid valves in the vertical direction with respect to the boundary surface 1a is a second position, and the first position and the second position are different. Therefore, since the positions of the fixing operations performed on the rotating portion 114a of the solenoid valve 100 and the rotating portion 814a of the solenoid valve 800 can be made different, the degree of freedom of the arrangement position when the plurality of solenoid valves are arranged in the upper body 2 can be increased, the solenoid valves can be arranged in a narrow space, and the volume and size of the control valve device 1 can be reduced.

The control valve device according to the above-described embodiment is mounted on a vehicle, for example. In addition, the structures of the above embodiments may be appropriately combined within a range not inconsistent with each other.
