Description

  The present invention relates to a valve body mounting structure for mounting a valve body such as a solenoid valve to a control body provided in an automatic transmission mounted on a vehicle.

  In an automatic transmission, a solenoid valve (valve element) is used to control a line pressure for shift control and a clutch pressure during shift. The solenoid valve is attached to the surface of a control body that incorporates a hydraulic control circuit included in the automatic transmission. Conventionally, as a method of attaching a solenoid valve to a control body, as shown in Patent Document 1, a method of fixing a solenoid valve with a comb-shaped (so-called guillotine-like) fixing piece (bracket), as shown in Patent Document 2, There is a method of fixing with a pin inserted into the solenoid valve. In the method of fixing with a comb-shaped fixing piece, U-shaped recesses formed in the fixing piece are fitted into slit-shaped cut grooves provided on the three outer surfaces of the solenoid valve. On the other hand, the method of fixing with a pin aligns the linear insertion groove provided on the outer surface of the solenoid valve with the insertion hole of the control body, and inserts and fixes the pin inserted into the insertion groove into the insertion hole of the body. It is like that.

JP 2002-156063 A JP 2007-187292 A

  In the method of fixing with a comb-shaped fixing piece shown in Patent Document 1, when installing the fixing piece, it is necessary to align (orient) the notch groove of the solenoid valve and the concave portion of the fixing piece. This alignment is performed by rotating a solenoid valve inserted into the mounting hole of the control body. When attaching a plurality of solenoid valves with one fixed piece, it is necessary to align all the solenoid valves at once. Therefore, it takes time and labor to install the solenoid valve. In particular, when the number of solenoid valves to be attached with one fixed piece increases, the above-described alignment operation becomes complicated, and the labor and time required for assembling the solenoid valve are greatly increased.

  Moreover, since the above comb-like fixed piece is a part manufactured by pressing, it has a constant thickness including the flange surface of the bolt. For this reason, there is a portion having a plate thickness that is not originally required. Moreover, the location fixed with a comb-shaped fixing piece, such as the shape for intensity | strength maintenance and the flange surface to fasten with a volt | bolt, is a complicated shape. As a result, there is a concern that the weight of the control body is increased and the structure is complicated.

  The comb-shaped fixing piece is attached to a solenoid valve, and is fixed by fastening a bolt from the upper surface side. For this reason, the bolt head protrudes to a position higher than the solenoid valve and the fixed piece. Thereby, there exists a problem that the thickness dimension of a control body becomes large.

  On the other hand, in the method of fixing a solenoid valve with a pin, when a plurality of solenoid valves are mounted, a pin corresponding to each solenoid valve, a stay for pin removal prevention, and a bolt for fixing the stay are required. Therefore, the number of parts required for the mounting structure increases, and the structure becomes complicated. Further, since it is necessary to insert a pin, set a pin retaining stay, and perform bolt tightening for each solenoid valve, a large number of man-hours are required for mounting the solenoid valve. In addition, there are many necessary parts processing such as bolt bearing surface processing, bolt hole (tap) processing, and pin hole processing.

  Further, as a problem common to the method of fixing with the above-mentioned comb-shaped fixing piece and the method of fixing with a pin, there is a point that a bolt dedicated to fixing / unlocking a component is required, and the number of components increases. In addition, there is a problem that the number of parts processing steps such as bolt hole processing and boss processing increases.

  The present invention has been made in view of the above points, and its purpose is to provide a simple structure that does not increase the number of parts and that simplifies the mounting process, while preventing the body from coming off and preventing rotation. It is in providing the attachment structure which can attach the valve body in.

  In order to solve the above problems, a valve body mounting structure according to the present invention includes a body (10) having a mounting surface (11) and a mounting surface (11) on the mounting surface (11) of the body (10). An insertion portion (13) that opens in a direction along the column, a columnar valve body (30) that is inserted in the axial direction with respect to the insertion portion (13) and is rotatably accommodated in the insertion portion (13), and an attachment A slit portion (15) extending in a direction intersecting the insertion direction of the valve body (30) with respect to the insertion portion (13) on the surface (11), and a cut formed on the outer peripheral surface (31) of the valve body (30). An insertion groove (35) and an elongated locking member (20) for locking the valve body (30) accommodated in the insertion section (13), the valve body (30) being inserted into the insertion section In the state inserted in (13), the valve body (30) is rotated so that the cut groove (35) faces the slit portion (15) side, and the By engaging the locking member (20) inserted into the groove portion (15) with the cut groove (35), the valve body (30) accommodated in the insertion portion (13) is prevented from coming off and rotating. It is characterized by comprising.

  In this mounting structure, on the mounting surface (11), a plurality of insertion portions (13) for inserting the plurality of valve bodies (30) are arranged side by side, and the slit portion (15) Each of the plurality of valve bodies (30) extends over a position corresponding to the insertion section (13), and the cut groove (35) of each of the plurality of valve bodies (30) faces the slit section (15) side. The locking member (20) inserted into the slit portion (15) is engaged with the cut groove (35) while rotating in order to align the direction, so that a plurality of valves can be operated with one locking member (20). It is preferable that the body (30) is prevented from coming off and rotating.

  According to the attachment structure of the valve body according to the present invention, by rotating the valve body inserted into the insertion portion, the notch groove is directed to the slit portion side, and the locking member inserted into the slit portion is used as the notch groove. By engaging, the valve body accommodated in the insertion portion is configured to be prevented from coming off and rotating. This eliminates the need to use bolts and other fasteners to attach the valve body to the body. A valve body can be attached. Moreover, since a fastener such as a bolt is not used for attaching the valve body, the height (thickness) dimension of the body to which the valve body is attached can be kept low. Therefore, the external dimensions of the body can be reduced.

  In the conventional mounting method using a comb-shaped fixing piece, the number of parts is small, but it is necessary to fix the valve bodies by aligning the directions of a plurality of valve bodies at one time, resulting in complicated operations. In addition, in the mounting method using pins, each of the plurality of valve bodies can be fixed by separate operations, so that the assembly workability of the individual valve bodies is good, but the number of parts is increased and the assembly process is complicated. . On the other hand, in the mounting structure according to the present invention, the number of parts can be reduced and the plurality of valve bodies can be assembled while being rotated in order, thereby simplifying the configuration and improving the assemblability. Both can be realized.

  In other words, in the mounting structure according to the present invention, the elongated locking member is inserted into the slit portion and sequentially engaged with the cut groove of each valve body to prevent the valve body from being detached and prevented from rotating. Even if the number of valve bodies increases, assembly work is easy. In addition, since the plurality of valve bodies can be prevented from coming off and prevented from rotating with a single locking member, the number of parts can be reduced, and the manufacturing cost can be reduced. In addition, less processing is required for the body and the valve body, and processing costs and labor can be reduced. Furthermore, since the slit portion and the locking member inserted into the slit portion can be formed in a relatively simple shape such as being formed in a straight line, for example, the processing cost of the component can be kept low.

  In the valve body mounting structure described above, a chamfered portion (36) formed by chamfering the cut groove (35) may be provided at at least one end of the cut groove (35). . According to this, the stay can be inserted into the notch groove only by adjusting the orientation of the valve body to some extent. Then, as the stay is inserted deeply into the cut groove, the valve body rotates and the cut groove faces the slit portion side. Therefore, since it becomes easy to perform the operation | work which makes a latching member engage with a notch groove, the efficiency of the attachment operation | work of a valve body can be improved more.

  In the valve body mounting structure described above, the locking member (20) has portions with different width dimensions (H1, H2) along the longitudinal direction thereof, and a plurality of valve bodies (30). By setting the notch grooves (35) included in each to different depth dimensions (L1, L2), the dimensions between the slit portion (15) and each of the plurality of notch grooves (35) facing each other are related. It is good to correspond to the width dimension (H1, H2) of a stop member (20). According to this, when different types of valve bodies are mounted on one mounting surface, it becomes possible to distinguish the mounting position of the valve body by the difference in the width dimension of the locking member, so that it is effective to misassemble the valve body. Will be able to prevent.

  In the valve body mounting structure described above, the locking member (20) has a contact portion (20) that contacts the valve body (30) in a state where the locking member (20) is inserted into the slit portion (15). 21) is provided, and the contact portion (21) is in contact with the valve body (30), so that the movement of the locking member (20) in the direction of coming out of the slit portion (15) is restricted. You can do it. Alternatively, other parts (17, 18) attached to the body (10) are provided, and the other parts (17, 18) are brought into contact with the locking member (20) inserted into the slit portion (15). The locking member (20) may be configured to be restricted from moving in a direction in which the locking member (20) is removed from the slit portion (15). According to these, since the movement of the locking member inserted into the slit portion in the removal direction can be restricted with a simple configuration, it is possible to maintain the valve body by the locking member and prevent the rotation of the valve body.

In the valve body mounting structure described above, the mounting surface (11) is vertically oriented and the slit portion (15) extends in the vertical direction in a state where the body (10) is mounted on the vehicle. The locking member (20) may be inserted and installed from the upper side to the lower side with respect to the slit portion (15). According to this, it becomes easy to perform the operation | work which inserts a locking member in a slit part and engages with the notch groove of a valve body. Therefore, the efficiency of the mounting operation of the valve body can be further improved. Further, it is possible to prevent the locking member from coming out of the slit portion without providing a separate structure for preventing the locking member installed by being inserted into the slit portion.
In addition, the code | symbol in said parenthesis shows the code | symbol of the corresponding component in embodiment mentioned later as an example of this invention.

  According to the mounting structure of the valve body according to the present invention, the valve body can be mounted in a state in which the body is prevented from being detached and prevented from rotating while the mounting process is simplified and the mounting process is simplified. Can be done.

FIG. 1 is a schematic perspective view showing a control body 10 to which a solenoid valve (valve body) 30 is attached. . 2A is a plan view showing the mounting surface 11 of the control body 10 to which the solenoid valve 30 is mounted, and FIG. 2B is a schematic cross-sectional view taken along line AA in FIG. FIG. 3 is a view showing a mounting state of the solenoid valve 30, and FIG. 3A is a partial schematic side view (partially sectional view) showing the solenoid valve 30 accommodated in the insertion hole 13 of the mounting surface 11. (B) is BB arrow sectional drawing of (a). In the sectional view, the internal structure of the solenoid valve 30 is not shown. The attachment structure of this embodiment is an attachment structure for attaching the solenoid valve 30 to the control body 10 having a hydraulic control circuit included in the vehicle automatic transmission.

  The control body 10 is a housing with a built-in hydraulic control circuit for speed change control, and is formed in a rectangular parallelepiped box shape with a thin outer shape. One surface (the upper surface in FIG. 1) of the outer side of the control body 10 is a mounting surface 11 to which the solenoid valve 30 is attached. The attachment surface 11 is provided with a mounting portion 12 formed in a semi-cylindrical shape. A plurality (three in the figure) of the mounting portions 12 are installed on the mounting surface 11. The plurality of mounting portions 12 are arranged side by side along a lateral direction orthogonal to the insertion direction of the solenoid valve 30. An insertion hole (insertion portion) 13 for inserting the solenoid valve 30 is formed in each mounting portion 12. The insertion hole 13 is formed as a cylindrical through hole whose axial direction extends in parallel with the mounting surface 11 so that a part of the solenoid valve 30 is inserted in a state where the rotation of the solenoid valve 30 is allowed. It has become. In the following description, the direction of insertion simply refers to the direction of insertion of the solenoid valve 30 into the insertion hole 13.

  As shown in FIG. 2A, the solenoid valve 30 includes a spool valve portion 30a and an electromagnetic actuator portion 30b that are provided coaxially with each other. The spool valve portion 30 a includes a sleeve 31 formed in a cylindrical shape and a spool (not shown) accommodated in the sleeve 31. The electromagnetic actuator portion 30 b has a cylindrical outer shape connected to the axial end of the sleeve 31.

  A narrow groove-like slit portion 15 is provided on the mounting surface 11 of the control body 10. The slit portion 15 is disposed in the vicinity of one end of the insertion hole 13 and extends across positions corresponding to the three insertion holes 13. As shown in FIGS. 1 and 2, the slit portion 15 is formed as a linear narrow groove extending in a direction orthogonal to the insertion direction. It is formed in a letter shape. As shown in FIG. 2, the front end 15 a of the slit portion 15 is closed by the standing wall 16, and the rear end 15 b is opened at the position of the end side of the mounting surface 11.

  On the other hand, a linear cut groove 35 is formed in the sleeve 31 of the solenoid valve 30. As shown in FIG. 3B, the cut groove 35 has a shape in which the outer periphery of the cylindrical sleeve 31 is cut linearly, and only one is formed on the outer periphery of the sleeve 31. As shown in FIG. 3A, the cut groove 35 has a substantially U-shaped cross section symmetrical to the cross section of the slit portion 15.

  A stay (locking member) 20 that is installed by being inserted into the slit portion 15 of the control body 10 is provided. As shown in FIGS. 1 and 2, the stay 20 is a straight thin plate made of a synthetic resin molded product or the like. As shown in FIG. The cross section of the groove 35 has a substantially rectangular cross section. The length of the stay 20 is slightly shorter than the length of the slit 15 in the longitudinal direction so that the entire length of the stay 20 is accommodated in the slit 15. In addition, as shown in FIG.2 (b), the stay 20 is good to make it the shape which cut off the corner | angular part of the front-end | tip 20a. In this way, the stay 20 can be easily engaged with the cut groove 35 of the solenoid valve 30.

  A procedure for mounting the solenoid valve 30 to the control body 10 with the mounting structure having the above configuration will be described. First, the spool valve portion 30 a of the solenoid valve 30 is inserted into the insertion hole 13 on the mounting surface 11. For this purpose, the spool valve portion 30 a is inserted in the insertion direction shown in FIG. 1, and the tip of the sleeve 31 is installed in a state of slightly protruding from one end of the insertion hole 13. Each solenoid valve 30 is installed in the same state with respect to each mounting portion 12. At this time, the sleeve 31 of each solenoid valve 30 is positioned directly above the slit portion 15 on the mounting surface 11. Thereafter, the stay 20 is inserted from the rear end 15 b of the slit portion 15. And the solenoid valve 30 accommodated in the insertion hole 13 is rotated, and the notch groove 35 is turned to the slit part 15 side. In this state, the stay 20 in the slit portion 15 is passed through the lower side of the solenoid valve 30 (the mounting surface 11 side), so that the stay 20 is inserted into the cut groove 35 and engaged. When the stay 20 is passed under each solenoid valve 30, the operation of rotating the solenoid valve 30 in the above-described procedure and directing the cut groove 35 toward the slit portion 15 is repeated. Engage with the cut groove 35. As a result, the stay 20 is engaged with the cut grooves 35 of the three solenoid valves 30, and the solenoid valves 30 inserted into the insertion holes 13 are prevented from coming off and rotating.

  FIG. 4 is a diagram illustrating a configuration example of the mounting structure according to the present embodiment, and is a cross-sectional view corresponding to the AA arrow in FIG. As shown in the figure, it is preferable to prevent the stay 20 inserted into the slit portion 15 from coming off with a bolt 17 fastened to the mounting surface 11. That is, in this case, the bolt 17 is fastened on the mounting surface 11 in the vicinity of the rear end 15 b of the slit portion 15 with the tip 20 a of the stay 20 inserted into the slit portion 15 being in contact with the standing wall 16. Although detailed illustration is omitted, the bolt 17 is not necessarily a dedicated component for preventing the stay 20 from being pulled out, but a fastener for fastening the control bodies 10 to each other or other components (such as an electric device). It is good to use the fixing tool for fixing to the attachment surface 11. FIG. With this bolt 17, the rear end 20 b of the stay 20 inserted into the slit portion 15 is pressed. Thereby, it is possible to prevent the stay 20 inserted into the slit portion 15 from coming off.

  As described above, in the mounting structure of the present embodiment, the insertion hole 13 for inserting the solenoid valve 30 in the direction along the mounting surface 11 of the control body 10 and the insertion direction of the solenoid valve 30 on the mounting surface 11. A slit portion 15 extending in the intersecting direction, a cut groove 35 formed in the sleeve 31 of the solenoid valve 30, and a long stay 20 for locking the solenoid valve 30 to the control body 10, With the solenoid valve 30 inserted into the insertion hole 13, the solenoid valve 30 is rotated so that the cut groove 35 faces the slit portion 15, and the stay 20 inserted into the slit portion 15 is inserted into the cut groove of the solenoid valve 30. By engaging with 35, the solenoid valve 30 inserted into the insertion hole 13 is configured to be prevented from coming off and rotating.

  A plurality of insertion holes 13 for inserting the plurality of solenoid valves 30 are arranged side by side on the mounting surface 11, and the slit portion 15 extends over a position corresponding to the plurality of insertion holes 13. The stays 20 are engaged with the cut grooves 35 while rotating the solenoid valves 30 in order so that the cut grooves 35 of the solenoid valves 30 face the slit portion 15 side. The stay 20 is configured to prevent the plurality of solenoid valves 30 from coming off and rotating.

  According to this mounting structure, it is not necessary to use a fastener such as a bolt for mounting the solenoid valve 30 to the control body 10, so that it has a simple mounting structure with a small number of parts, but is prevented from coming off and rotating. The solenoid valve 30 can be easily attached in the state. Moreover, since a fastener such as a bolt is not used for mounting the solenoid valve 30, the height (thickness) dimension of the control body 10 to which the solenoid valve 30 is mounted can be kept low. That is, in this mounting structure, since the stay 20 is disposed on the lower side (the mounting surface 11 side) of the solenoid valve 30, compared to the conventional mounting method using a comb-shaped fixing piece or the mounting method using a pin, The height dimension from the mounting surface 11 of the mounting structure can be kept low.

  In addition, in the conventional mounting method using a comb-shaped fixing piece, the number of parts is small, but it is necessary to fix the directions of a plurality of solenoid valves at the same time, resulting in complicated operations. Also, in the conventional mounting method using pins, each of the plurality of solenoid valves can be fixed by separate work, so the assembly work of each solenoid valve is good, but the number of parts increases and the mounting process becomes complicated. It was. On the other hand, in the mounting structure of the present embodiment, the number of parts can be reduced and each of the plurality of solenoid valves 30 can be mounted in order, thereby realizing both simplification of the configuration and improvement of mounting properties. it can.

  That is, in the mounting structure of the present embodiment, the long stay 20 is inserted into the slit portion 15 and sequentially engaged with the cut grooves 35 of the plurality of solenoid valves 30, thereby preventing the solenoid valve 30 from coming off. Since the rotation is stopped, the assembly work is easy even if the number of solenoid valves 30 to be attached is increased. Further, since the plurality of solenoid valves 30 can be prevented from being detached and prevented from rotating with one stay 20, the number of parts can be reduced, and the manufacturing cost can be reduced. Further, less processing is required for the control body 10 and the solenoid valve 30, and processing costs and labor can be reduced. Furthermore, since the stay 20 inserted into the slit portion 15 may be formed in a relatively simple shape such as being formed in a straight bar shape as in the present embodiment, the processing cost of the parts can also be kept low in this respect. .

[Second Embodiment]
Next, a second embodiment of the present invention will be described. In the description of the second embodiment and the corresponding drawings, the same or corresponding components as those in the first embodiment are denoted by the same reference numerals, and detailed description thereof will be omitted below. In addition, matters other than those described below are the same as those in the first embodiment. This is the same in other embodiments.

  FIG. 5 is a view showing a mounting structure according to the second embodiment of the present invention, and is a view showing a cross section corresponding to the arrow A-A in FIG. In the present embodiment, chamfered portions 36 are provided at both ends of the cut groove 35 of the solenoid valve 30. The chamfered portion 36 has a configuration in which the end portion of the cut groove 35 is chamfered by digging deeper than other portions. If such a chamfered portion 36 is provided, when the tip 20a of the stay 20 is inserted into and engaged with the cut groove 35, the cut groove 35 is not completely parallel to the slit portion 15, and is slightly Even when it has an angle, the chamfered portion 36 opens the gap between the cut groove 35 and the slit portion 15 widely. Therefore, the stay 20 can be inserted into the cut groove 35 by adjusting the direction of the solenoid valve 30 to some extent. Then, as the stay 20 is inserted deeply into the cut groove 35, the solenoid valve 30 rotates and the cut groove 35 faces the slit portion 15 side. Therefore, the operation of inserting the stay 20 into the cut groove 35 and facilitating the installation operation can be facilitated, and the efficiency of the operation of mounting the solenoid valve 30 can be further improved. Although FIG. 5 shows the case where the chamfered portions 36 are provided at both ends of the cut groove 35, the chamfered portions 36 may be provided only at one end of the cut groove 35.

[Third Embodiment]
Next, a third embodiment of the present invention will be described. FIG. 6 is a view showing a mounting structure according to the third embodiment of the present invention, and is a view showing a cross section corresponding to the arrow AA in FIG. In the mounting structure of the present embodiment, the width dimension (height dimension) of the stay 20 is varied from H1 to H2 (H1> H2) in the middle of the longitudinal direction. In addition, the depth dimensions of the cut grooves 35 included in the plurality of solenoid valves 30 are different from each other. That is, among the three solenoid valves 30 shown in the figure, the cut grooves 35 of the two solenoid valves 30 have a depth dimension of L1, whereas the cut grooves of one solenoid valve 30 have the depth dimension L1. No. 35 has a depth dimension L2 (L1> L2). Accordingly, the dimension between the slit portion 15 and each of the plurality of cut grooves 35 facing the slit portion 15 is made to correspond to the width dimension of each portion of the stay 20.

  With the above-described configuration, the plurality of solenoid valves 30 installed side by side in the longitudinal direction of the stay 20 are mounted unless they have the notch grooves 35 having a depth suitable for the width of the corresponding stay 20. Can not. As a result, when a plurality of different types of solenoid valves 30 are mounted on one mounting surface 11, the mounting locations of the different types of solenoid valves 30 can be distinguished depending on the width of the stay 20. Therefore, erroneous assembly of the solenoid valve 30 can be effectively prevented.

[Fourth Embodiment]
Next, a fourth embodiment of the present invention will be described. FIG. 7 is a view showing a mounting structure according to the fourth embodiment of the present invention, and is a view showing a cross section corresponding to the arrow AA in FIG. In the mounting structure of the present embodiment, the stay 20 inserted into the slit portion 15 is prevented from coming off by a cover 18 installed on the mounting surface 11 instead of the bolt 17 (see FIG. 4) provided in the mounting structure of the first embodiment. Is configured to do. The cover 18 has a side wall 18 a and an upper wall 18 b, is formed in a container shape that opens to the mounting surface 11 side, and is placed over the solenoid valve 30 on the mounting surface 11.

  Here, with the tip 20 a of the stay 20 inserted into the slit portion 15 in contact with the standing wall 16, the cover 18 is placed on the mounting surface 11. The cover 18 is fixed to the mounting surface 11 by fastening bolts 19 or the like. The side wall 18 a of the cover 18 is brought into contact with the rear end 20 b of the stay 20 inserted into the slit portion 15. Thereby, it is possible to prevent the stay 20 from coming off from the slit portion 15.

  In the present embodiment, a cover 18 attached to the attachment surface 11 of the control body 10 is provided, and the stay 20 is brought into contact with a stay 20 inserted between the slit portion 15 and the cut groove 35 so that the stay 20 The movement in the pull-out direction is restricted. According to this, the movement of the stay 20 inserted into the slit portion 15 in the removal direction can be restricted with a simple configuration in which the number of parts is reduced. Accordingly, it is possible to maintain the solenoid valve 30 from being prevented from coming off and rotating by the stay 20.

[Fifth Embodiment]
Next, a fifth embodiment of the present invention will be described. FIG. 8: is a figure which shows the attachment structure concerning 5th Embodiment, (a) is a figure which shows the cross section corresponding to the AA arrow of FIG. 2 (a), (b) is a figure of (a). FIG. In the mounting structure of the present embodiment, a claw piece (contact portion) 21 that comes into contact with the solenoid valve 30 provided at the tip 20a of the stay 20 is provided. The claw piece 21 protrudes from the upper surface 20 c in the vicinity of the tip 20 a of the stay 20 and is formed in a strip shape extending obliquely upward toward the rear end 20 b of the stay 20. The claw piece 21 is connected to the stay 20 with a slight elasticity at the base portion. Thus, when the claw piece 21 is pressed from the front, the claw piece 21 becomes parallel to the upper surface 20c of the stay 20, while when the pressing force is released, the claw piece 21 is separated from the upper surface 20c of the stay 20. And it is comprised so that it may extend diagonally upward. Therefore, when the stay 20 inserted into the slit portion 15 is engaged with the cut groove 35 of the solenoid valve 30, the claw piece 21 is folded in parallel with the upper surface 20 c of the stay 20. You don't need to get in the way. On the other hand, when the claw piece 21 exceeds the cut groove 35, the folded claw piece 21 is elastically separated from the upper surface 20 c of the stay 20. Thus, as shown in FIG. 8, the tip of the claw piece 21 is in a state of facing the sleeve 31 of the solenoid valve 30. Therefore, when the stay 20 is to move in the direction (rear side), the claw piece 21 comes into contact with the sleeve 31 of the solenoid valve 30 and its movement is restricted. Thereby, it is possible to prevent the stay 20 inserted into the slit portion 15 from coming off.

  As described above, in the configuration example shown in FIG. 8, the claw piece (contact portion) 21 is in contact with the solenoid valve 30, thereby restricting the stay 20 inserted into the slit portion 15 from moving in the removal direction. Therefore, since the movement of the stay 20 in the removal direction can be restricted with a simple configuration, it is possible to maintain the solenoid valve 30 from being prevented from coming off and being prevented from rotating by the stay 20. Note that the claw piece 21 may be formed integrally with the stay 20, or a piece formed of a separate part from the stay 20 may be attached to the tip 20 a of the stay 20.

[Sixth Embodiment]
Next, a sixth embodiment of the present invention will be described. FIG. 9 is a view showing a mounting structure according to the sixth embodiment and is a view showing a state in which the control body 10 is installed in a vehicle (a state in which a transmission to which the control body 10 is attached is mounted in the vehicle). In the mounting structure of the sixth embodiment, the control body 10 is installed such that the mounting surface 11 provided with the mounting portion 12 is vertically oriented and the slit portion 15 extends in the vertical direction in a state where the control body 10 is mounted on the vehicle. Has been. The slit portion 15 has an upper rear end 15 b opened and a lower tip 15 a closed by a standing wall 16. The stay 20 is inserted into the slit portion 15 extending in the vertical direction from the upper side to the lower side.

  In the present embodiment, since the stay 20 is inserted into the slit portion 15 from the upper side toward the lower side, the operation of inserting the stay 20 into the slit portion 15 and engaging with the cut groove 35 is facilitated. Therefore, the efficiency of the mounting operation of the solenoid valve 30 can be further improved. Further, the stay 20 can be maintained in the state of being installed in the slit portion 15 by its own weight without providing a separate structure for preventing the stay 20 inserted into the slit portion 15 from falling off. Therefore, it is possible to prevent the stay 20 from coming off from the slit portion 15.

  Although the embodiments of the present invention have been described above, the present invention is not limited to the above-described embodiments, and various modifications can be made within the scope of the technical idea described in the claims and the specification and drawings.
