  The other longitudinal side portion of the holding member 60 is disposed to pass through the upper body 11 at the upper side of the vehicle body, and is attached to the electronic control unit 32 at its tip end (see FIG. 1).

  As shown in FIGS. 2 to 5, the holding member 60 has an outer side surface 61 disposed to face the outer side of the valve body 10 and an outer peripheral surface of the upper body 11 facing the inner side of the outer side surface 61. And an upper surface portion 63 connecting the upper end portions of the outer side surface portion 61 and the inner side surface portion 62. As shown in FIG.

  The cross-sectional shape of the holding member 60 is basically a U-shape opened to the lower side of the vehicle body. The plurality of cables 50 are exposed at the connecting portion with the connector portion 46 and the peripheral length portion thereof, but the remaining length portions are accommodated in the internal space of the holding member 60. Thereby, positioning, protection and electrical insulation of the cable 50 by the holding member 60 are achieved.

  The outer side surface 61 is provided with an opening 68 for inserting a portion of the cable 50 extending from the connector 46 to the inside of the holding member 60. The opening 68 is formed, for example, in a slit shape extending in the vertical direction of the vehicle body and opened to the lower side of the vehicle body. A plurality of openings 68 are provided at intervals in the length direction of the holding member 60. Each opening 68 is disposed in the vicinity of the corresponding connector portion 46.

  As shown in FIGS. 3 to 5, the holding member 60 includes a plurality of support portions 64 for supporting the cable 50 from the lower side of the vehicle body. The plurality of support portions 64 are spaced apart from each other in the length direction of the holding member 60. Each support portion 64 is disposed, for example, at a position adjacent to the electronic control unit 32 side of the opening 68 in the length direction of the holding member 60.

  The support portion 64 is a plate-like portion capable of opening and closing the lower end opening portion of the holding member 60. The support portion 64 is integrally connected to the lower end portion of the inner side surface portion 62. The support portion 64 is arranged to extend from the lower end portion of the inner side surface portion 62 toward the lower end portion of the outer side surface portion 61 in a state in which the lower end opening portion of the holding member 60 is closed.

  The holding member 60 further includes an extension 65 integrally connected to the tip of the support 64. The support portion 64 and the extension portion 65 are integrally formed with the holding member 60. However, the support portion 64 and the extension portion 65 which are separate from the holding member 60 may be attached to the holding member 60.

  The extension portion 65 is provided with an engagement hole 66 engageable with the outer side surface portion 61 of the holding member 60. In the state where the lower end opening of the holding member 60 is closed by the support portion 64, the extension portion 65 is disposed along the outer surface of the outer side surface portion 61 so as to extend from the tip end portion of the support portion 64 to the vehicle body upper side. It is possible. Thus, in the state where the support portion 64 and the extension portion 65 are arranged, the engagement hole 66 of the extension portion 65 can be engaged with the engagement convex portion 67 which protrudes outward from the outer side surface portion 61. .

  In the state in which the engagement convex portion 67 and the engagement hole 66 are engaged, the support portion 64 is positioned so as to close the lower end opening of the holding member 60. In this state, the cable 50 accommodated in the inside of the holding member 60 can be supported from the vehicle body lower side by the support portion 64, whereby the detachment of the cable 50 can be suppressed.

  On the other hand, in a state where the engagement between the engagement convex portion 67 and the engagement hole 66 is released, the tip end portion of the support portion 64 and the extension portion 65 are separated from the outer side surface portion 61, and the lower end opening of the holding member 60 Can be released. Thus, in the portion where the support portion 64 is opened, the cable 50 can be taken in and out from the holding member 60.

  However, the specific configuration for opening and closing the support portion 64 is not limited to the above configuration, and various modifications are possible.

  As shown in FIGS. 2 to 4, the holding member 60 includes an attached portion 70 attached to the valve body 10 by, for example, a snap fit. A plurality of mounting portions 70 are provided at intervals in the length direction of the holding member 60. The plurality of attached portions 70 are provided in the length direction portion arranged along the outer peripheral surface of the upper body 11 in the holding member 60.

  As shown in FIG. 3, FIG. 4 and FIG. 6, the holding member 60 is provided with a base portion 69 for supporting the mounting portion 70. FIG. 6 is a cross-sectional view schematically showing the mounting portion 70 provided at the end of the holding member 60 in the longitudinal direction and the periphery thereof.

  The base portion 69 is provided to connect the lower end portion of the outer side surface portion 61 and the lower end portion of the inner side surface portion 62. The base portion 69 is, for example, a plate-like portion facing the upper surface portion 63. The base portion 69 is provided at each longitudinal position corresponding to the mounting portion 70 in the holding member 60.

  Although the base portion 69 shown in FIGS. 3, 4 and 6 is provided in the length portion of the holding member 60 where the cable 50 is not accommodated, the base portion 69 is provided in the length portion where the cable 50 is accommodated. May be provided.

  When the cable 50 accommodated in the holding member 60 is disposed to pass through the vehicle body upper side of the base portion 69, the base portion 69 has the same function as the above-described support portion 64 in addition to the function of supporting the attached portion 70. The function of supporting the cable 50 in the holding member 60 from the lower side of the vehicle body is also provided. In this case, the base portion 69 may be provided so as to be able to open and close the lower end opening of the holding member 60 as in the case of the support portion 64 described above.

  The mounting portion 70 is provided to project downward from the base portion 69 toward the vehicle body. The base portion 69 and the mounting portion 70 are integrally formed with the holding member 60.

  However, the base portion 69 and the mounting portion 70 which are separate from the holding member 60 may be attached to the holding member 60, or the base portion 69 integrally formed with the holding member 60 is the holding member 60. A separate attached portion 70 may be attached. In addition, when the to-be-attached part 70 separate from the holding member 60 is used, it is preferable that the to-be-attached part 70 consists of elastic materials, such as resin.

  As shown in FIG. 6, the mounting portion 70 has a first leg 71 and a second leg 72 which bifurcate and extend toward the tip. At an intermediate portion of the first leg portion 71, a first engagement convex portion 73 projecting to the opposite side to the second leg portion 72 is provided. At an intermediate portion of the second leg portion 72, a second engagement convex portion 74 which protrudes to the opposite side to the first leg portion 71 is provided. The mounting portion 70 further includes a pair of arm portions 75 and 76 extending obliquely downward from the proximal end of the first leg 71 and the proximal end of the second leg 72, respectively.

  The attached portion 70 of the holding member 60 can be attached to the separate plate 20 of the valve body 10. In order to enable attachment of the mounting portion 70 to the separate plate 20, the separate plate 20 is provided with a projecting portion 22 projecting outward beyond the mating surfaces 13 and 14 of the upper body 11 and the lower body 12 .

  As shown in FIG. 2, the overhanging portion 22 is provided at a circumferential position corresponding to the mounting portion 70 in the separate plate 20. In the illustrated example, two overhanging portions 22 are provided on the separate plate 20. The overhanging portions 22 are disposed so as to be accommodated in the recess 10 a provided on the outer peripheral surface of the valve body 10. Thereby, the protrusion of the overhang part 22 to the outer side of the valve body 10 is suppressed. Each overhanging portion 22 is provided with a mounting hole 24 as a mounting portion to which the holding member 60 is mounted.

  As shown in FIGS. 2 and 6, the holding member 60 disposed along the outer peripheral surface of the upper body 11 as described above is disposed on the vehicle body upper side relative to the separate plate 20. Therefore, the holding member 60 is attached to the attachment hole 24 of the separate plate 20 from the upper body 11 side, that is, the vehicle body upper side.

  When attaching the holding member 60 to the separate plate 20, the attached portion 70 of the holding member 60 may be inserted into the attachment hole 24 of the separate plate 20 from the upper side of the vehicle body. When passing through the mounting hole 24, the first leg 71 and the second leg 72 of the mounting portion 70 elastically deform so that the tip end portions approach each other. Thereby, the distance between the tip of the first engagement convex portion 73 and the tip of the second engagement convex portion 74 is shortened, so that the first engagement convex portion 73 and the second engagement convex portion 74 can be attached to the mounting holes. You can go through 24.

  When the mounting portion 70 is inserted into the mounting hole 24, in the pair of arm portions 75 and 76 of the mounting portion 70, the first engagement convex portion 73 and the second engagement convex portion 74 pass through the mounting hole 24. Before the contact, the upper surface of the overhang 22 of the separate plate 20 is brought into contact.

  When the first engagement convex portion 73 and the second engagement convex portion 74 pass through the mounting hole 24, the elastically deformed first leg portion 71 and the second leg portion 72 are restored to their natural shapes, so that the separate plate is separated. The first engagement convex portion 73 and the second engagement convex portion 74 are engaged with the lower surface of the overhang portion 22 of FIG.

  At this time, the pair of arm portions 75 and 76 are engaged with the upper surface of the overhang portion 22 in a state of being elastically deformed such that the tip end is displaced outward. Thus, the mounting portion 70 projects the overhanging portion 22 in a state in which the overhanging portion 22 is sandwiched from above and below by the pair of arm portions 75 and 76 and the first engagement convex portion 73 and the second engagement convex portion 74. It is fixed to

  As described above, attachment of the holding member 60 to the extension 22 of the separate plate 20 can be easily performed by simply inserting the attachment 70 of the holding member 60 from the vehicle body upper side into the attachment hole 24 of the extension 22. Can. By fixing the holding member 60 to the overhanging portion 22, the cable 50 held by the holding member 60 is attached to the overhanging portion 22 via the holding member 60.

  When the attached portion 70 is removed from the overhang portion 22, the distal end portion of the attached portion 70 is pinched so that the distal end portions of the first leg 71 and the second leg 72 approach each other. The engagement of the first engagement convex portion 73 and the second engagement convex portion 74 with the lower surface of the protrusion 22 may be released. Thus, the mounting portion 70 can be pulled out from the mounting hole 24 of the overhang portion 22 to the vehicle body upper side.

  According to the present embodiment, the attachment of the cable 50 and the holding member 60 for holding the same to the valve body 10 can be performed using the separate plate 20. Therefore, the number of dedicated parts used for attaching the cable 50 and the holding member 60 can be reduced, and the number of assembling steps can be reduced.

  In addition, the plurality of cables 50 housed in the holding member 60 are routed along the length direction of the holding member 60 while being appropriately supported by the support portion 64 even if they are not bundled by the binding band. Therefore, while being able to reduce a binding band, the effort which bundles the several cable 50 can be saved.

  Furthermore, since the holding member 60 can be held using the separate plate 20, in the valve body 10, the number of bolt holes and bolt bosses for fixing the holding member 60 can be reduced. Therefore, the structure of the valve body 10 can be simplified and made compact.

  Furthermore, the reduction in the number of bolts fastened to the valve body 10 makes it easier to prevent the oil passage and peripheral parts in the valve body 10 from interfering with the bolts and bolt bosses. Therefore, the design freedom of the oil passage in the valve body 10 and peripheral parts such as the electronic control unit 32, various sensors 33 and 34, and parts (not shown) of the parking mechanism arranged around the valve body 10 The degree of freedom in layout can be improved.

  Also, the solenoid valve 42 is provided on the lower body 12, the cable 50 and the holding member 60 are disposed closer to the upper body 11 than the separate plate 20, and the holding member 60 is an overhanging portion of the separate plate 20 from the upper body 11 side. Since it is attached to 22, it is possible to simplify and shorten the wiring of the cable 50 while easily avoiding the interference of the cable 50 and the holding member 60 with the solenoid valve 42.

  Furthermore, since the connector portion 46 of the solenoid valve 42 is provided in the portion of the solenoid portion 44 on the upper body 11 side, the cable from the opening 68 of the holding member 60 disposed on the upper body 11 side to the connector portion 46 50 can be simplified and shortened.

  Further, shortening of the exposed cable 50 between the connector portion 46 and the opening 68 can reduce the deflection of the cable 50 at the exposed portion. Therefore, the wear and damage of the cable 50 can be suppressed by suppressing the contact between the cable 50 and the peripheral parts.

  As mentioned above, although the present invention was described with the above-mentioned embodiment, the present invention is not limited to the above-mentioned embodiment.

  For example, the configuration of the holding member 60 described in the above-described embodiment is merely an example, and various configurations other than the above-described configuration can be adopted as a holder that holds the cable. For example, the holding member 60 may have a cross-sectional shape open to the side or the upper side of the vehicle body.

  Further, the configurations of the attached portion 70 and the mounting hole 24 described above are merely an example, and the configuration for attaching the holding member 60 to the overhang portion 22 of the separate plate 20 is not particularly limited. For example, a through hole may be provided in the holding member 60, and an engagement portion fixed to the through hole by a snap fit or the like may be provided in the overhang portion 22 of the separate plate 20.
