[0020] Figure 7 This is a diagram illustrating the configuration of the wiring harness. Detailed Implementation

[0021] The following description will take the case where the vehicle of the present invention is a vehicle V having a belt-type continuously variable transmission 1 as an example.

[0022] Figure 1 This is a diagram illustrating the continuously variable transmission 1, a perspective view of the continuously variable transmission 1 as seen from the side cover 3.

[0023] Figure 2 This is a diagram illustrating the engine compartment R of vehicle V. Figure 2 (a) is a top view of the engine compartment R. The outline of the vehicle V is represented by dashed lines. Figure 2 (b) is Figure 2 (a) is a three-dimensional view of region A.

[0024] It should be noted that the front-to-back, left-to-right, and up-down directions in the attached diagram are used to illustrate the directions observed by the driver riding in vehicle V. Additionally, for ease of explanation, the wiring harness H has been omitted.

[0025] like Figure 1 As shown, the continuously variable transmission 1's transmission housing 2 consists of a side cover 3, a housing 4, and a converter housing 5. Inside the transmission housing 2 are rotating components such as a transmission mechanism (not shown) and friction fastening elements.

[0026] In the transmission housing 2, from one side separated by housing 4 ( Figure 1 A side cover 3 is installed on the front side of the paper in the middle, and from the other side ( Figure 1 The converter housing 5 is installed on the paper depth side. The housing 4 and the side cover 3 are fixed together by bolts B. The housing 4 and the converter housing 5 are fixed together by bolts B.

[0027] like Figure 2 As shown in (a), the engine ENG is adjacent to the converter housing 5 side of the transmission housing 2. Specifically, the transmission housing 2 is mounted on the engine ENG (see reference 1) with the side cover 3, housing 4, and converter housing 5 aligned in the X direction of the crankshaft (not shown) of the engine ENG. Figure 1 , Figure 2 (a)).

[0028] A rotational driving force generated by the crankshaft of the engine ENG around the rotation axis X is input to the continuously variable transmission 1. This rotational driving force is transmitted to a drive wheel (not shown) after being changed by a transmission mechanism within the transmission housing 2.

[0029] like Figure 2 As shown in (a), vehicle V has an engine compartment R on its front side in the longitudinal direction of vehicle V. An engine ENG and a continuously variable transmission (CVT) 1 are housed in the engine compartment R. The engine ENG is housed in the engine compartment R with the crankshaft's rotation axis X aligned with the left-right direction of vehicle V. The CVT 1 is positioned to the left of the engine ENG in the left-right direction of vehicle V. In the left-right direction of vehicle V, the total length W1 of the engine ENG and CVT 1 is slightly shorter than the length W2 of the engine compartment R (W1 < W2).

[0030] Side beams 6 (6L, 6R) of vehicle V are located on the left and right sides of the engine compartment R in the left-right direction. Side beams 6 (6L, 6R) are steel plate guide rail components that extend along straight lines Lm1 and Lm2 parallel to the front-rear direction of vehicle V.

[0031] like Figure 2 As shown in (a), the front end of the side beams 6 (6L, 6R) in the longitudinal direction of vehicle V ( Figure 2 (a) The right side is connected by the front crossbeam 7. The front crossbeam 7 is a steel plate guide rail component that extends along a straight line Ln1, which is orthogonal to straight lines Lm1 and Lm2. Straight line Ln1 is also a straight line parallel to the left-right direction of the vehicle V.

[0032] It should be noted that, although not shown in the figure, the rear ends of the side beams 6 (6L, 6R) are connected by a buffer plate.

[0033] The engine compartment R is a space surrounded by the aforementioned side beams 6 (6L, 6R), front crossbeam 7, and buffer plate.

[0034] like Figure 2 As shown in (a), in the left-right direction of the vehicle V, the side cover 3 of the transmission housing 2 is opposite to the side beam 6L, and the right side of the engine ENG is opposite to the side beam 6R.

[0035] In the left-right direction of the vehicle V, mounting members 8 (8L, 8R) are provided on the side beams 6 (6L, 6R) opposite to the engine ENG and transmission housing 2, respectively. The engine ENG and transmission housing 2 are supported on the side beams 6 (6L, 6R) via the mounting members 8 (8L, 8R).

[0036] Figure 3 This is a diagram illustrating the support structure of the continuously variable transmission 1. Figure 3 (a) is a schematic representation Figure 2 (a) BB section diagram. Figure 3 (b) is Figure 3 (a) CC vector diagram.

[0037] Figure 4 This is a diagram illustrating the housing 4 of the transmission housing 2. Figure 4 (a) is Figure 2 (b) A perspective view of the area around rib 413 of the shell 4. Figure 4 (b) is Figure 4 (a) Top view. It should be noted that, for ease of explanation, the support plate component 9 has been omitted.

[0038] Figure 5 This is a diagram illustrating the fixed bracket 82. Figure 5 (a) only indicates Figure 3 (b) is a diagram of the fixed bracket 82. Figure 5 (b) is a perspective view of the fixed bracket 82.

[0039] Figure 6 This is a diagram illustrating the support plate component 9. Figure 6 (a) is a perspective view of the support plate component 9. Figure 6 (b) is a top view of the support plate component 9.

[0040] [Shell 4]

[0041] like Figure 3 As shown in (a), the aforementioned transmission mechanism and friction fastening elements, as well as other rotating components, are housed within a storage space K inside the housing 4. The storage space K is surrounded by an annular wall 41 of the housing 4. The area surrounded by the annular wall 41 of the housing 4 opens onto the side beam 6L in the left-right direction of the vehicle V. This opening is sealed by a side cover 3.

[0042] At the end of the side cover 3 of the annular wall portion 41 in the left-right direction of the vehicle V, there is a flange portion 42 that engages with the flange portion 32 of the side cover 3 (see reference). Figure 1 , Figure 3 (b)).

[0043] The flange portion 42 is in the thickness direction of the annular wall portion 41. Figure 3 (a) In the vertical direction, it extends outward from the annular wall portion 41. The flange portion 42 is provided around the entire circumference of the annular wall portion 41 (see reference). Figure 1 In the flange portion 42, a plurality of boss portions 43 are provided at predetermined intervals in the circumferential direction for inserting bolts B from the side cover 3 (see reference). Figure 1 ).

[0044] like Figure 3 , Figure 4 As shown, a boss 411 is provided near the apex of the flange 42 in the vertical direction of the vehicle V. The boss 411 extends upward from the flange 42 in the vertical direction.

[0045] like Figure 4 As shown in (a), the front end face 411a of the boss portion 411 is a flat surface orthogonal to the vertical direction of the vehicle V. The screw hole 411b opens at the front end face 411a.

[0046] A rib 413 is formed at the root 411c of the boss portion 411. The rib 413 is provided across the side of the boss portion 411 opposite to the side cover 3 and the annular wall portion 41. The rib 413 is provided along a straight line Ln2 parallel to the left-right direction of the vehicle V, covering approximately the entire length of the annular wall portion 41 (see reference). Figure 4 (b)). The support plate component 9, described later, is fastened to the boss portion 411 by bolt B while in contact with the front end face 411a (see reference). Figure 3 ).

[0047] [Side Cover 3]

[0048] like Figure 3 As shown in (a), the side cover 3 is composed of a bottom wall portion 30, a peripheral wall portion 31 surrounding the bottom wall portion 30, and a flange portion 32 provided throughout the entire circumference of the opening edge of the peripheral wall portion 31. The flange portion 32 is in a direction parallel to the bottom wall portion 30 ( Figure 3 (a) is provided in the vertical direction, extending outward from the peripheral wall portion 31.

[0049] The mating surface 42a of flange portion 42 and the mating surface 32a of flange portion 32 are in the same direction as flange portions 42 and 32. Figure 3 (a) is a flat surface that is orthogonal to the left and right directions.

[0050] In the flange portion 32, bolt bosses 33 are provided at predetermined intervals in the circumferential direction for a plurality of through bolts B (see reference). Figure 1 The bolt boss 33 is provided at a position that corresponds one-to-one with the boss portion 43 of the flange portion 42.

[0051] A protrusion 35 is provided on the side 30a of the bottom wall portion 30 in the left-right direction of the vehicle V, opposite to the flange portion 32. The protrusion 35 is composed of three protrusions 351, 352, and 353 protruding from the side 30a of the bottom wall portion 30 (see reference). Figure 1 and Figure 3 (a)).

[0052] like Figure 1 As shown, the three protrusions 351, 352, and 353 are arranged in a row with intervals along the front-rear direction of the vehicle V. The upper surface 351a of protrusion 351, the upper surface 352a of protrusion 352, and the upper surface 353a of protrusion 353 are flat surfaces orthogonal to the vertical direction and are formed on the same plane.

[0053] Each screw hole 351b, 352b, and 353b opens on the upper surface 351a of protrusion 351, the upper surface 352a of protrusion 352, and the upper surface 353a of protrusion 353.

[0054] The aforementioned screw holes 351b, 352b, and 353b are located at positions where they intersect with a straight line Lm3 parallel to the front-rear direction of the vehicle V.

[0055] The mounting bracket 82 of the mounting component 8L is connected to the protrusion 35 of the side cover 3 by bolt B (see reference). Figure 3 ).

[0056] [Mounting components 8L]

[0057] like Figure 3 (a) Figure 3 As shown in (b), mounting component 8L is mounted on side beam 6L.

[0058] The mounting component 8L consists of a cylindrical base 80, an elastic member 81 embedded in the inner diameter side of the base 80, and a fixing bracket 82 inserted in the elastic member 81.

[0059] like Figure 3 As shown in (b), the mounting component 8L is mounted on the side beam 6L with the centerline Cx of the base 80 aligned with the left-right direction of the vehicle V. Therefore, the centerline Cx of the base 80 is orthogonal to the long side direction (straight line Lm1) of the side beam 6L.

[0060] In this state, the diameter line Cy of the base 80, which is parallel to the front-rear direction of the vehicle V, is parallel to the long side direction (straight line Lm1) of the side beam 6L.

[0061] The base 80 is fixed to the side beam 6L via support plates 801 and 802. The support plates 801 and 802 extend in a direction that is separate from the outer peripheral surfaces 80a and 80a of the base 80.

[0062] like Figure 2 (b) Figure 3 As shown in (b), support plates 801 and 802 are disposed on the front side (lower side in the figure) and the rear side (upper side in the figure) of the base 80 separated by the center line Cx.

[0063] Support plates 801 and 802 each extend in the direction of the diameter line Cy, in a direction separate from the base 80.

[0064] It should be noted that support piece 801 and support piece 802 have the same shape. In the following description, support piece 801 will be used as an example.

[0065] like Figure 3As shown in (b), the support piece 801 is formed by bending a strip-shaped member. The support piece 801 is composed of a planar portion 801a parallel to the center line Cx, and support portions 801c and 801c orthogonal to the planar portion 801a.

[0066] A through hole 801b is formed in the planar portion 801a, extending through the planar portion 801a in the thickness direction. Bolt B is inserted into the through hole 801b.

[0067] With the flat portion 801a positioned on the upper surface 6a of the side beam 6L, the base 80 is fixed to the side beam 6L by bolts B.

[0068] Support portions 801c, 801c are provided on the side edges of one side and the other side of the planar portion 801a in the direction of the center line Cx of the base 80. Support portions 801c, 801c are provided across the outer periphery of the base 80 and the planar portion 801a.

[0069] like Figure 3 As shown in (a), an elastic member 81 is embedded in the inner diameter side of the base 80. The material of the elastic member 81 is, for example, anti-vibration rubber.

[0070] The elastic member 81 has a total length L2 that is slightly longer than the total length L1 of the base 80 in the center line Cx direction (L1 < L2). In addition, when the elastic member 81 is embedded in the base 80, the end 81a of the side cover 3 in the center line Cx direction is exposed in the engine compartment R.

[0071] The outer diameter r1 of the end 81a side of the elastic member 81 is formed to be a larger diameter than the outer diameter r2 of the base 80 (r1 > r2). This prevents the elastic member 81 from moving in the direction of separation from the side cover 3 in the direction of the center line Cx.

[0072] A second bracket portion 84 of a fixing bracket 82 is inserted into the elastic member 81 along the centerline Cx direction. A first bracket portion 83 of the fixing bracket 82 protrudes from the end 81a of the elastic member 81. The first bracket portion 83 is exposed inside the engine compartment R. That is, the fixing bracket 82 (the component on the housing component side) of the mounting component 8L is connected to the base 80 (the component on the frame side) of the mounting component 8L via the elastic member 81.

[0073] The first bracket portion 83 of the fixed bracket 82 is connected to the side cover 3 inside the engine compartment R, and is also connected to the housing 4 via the support plate member 9 (see reference). Figure 3 ).

[0074] [Fixed bracket 82]

[0075] like Figure 3 (a) Figure 5As shown, the fixed bracket 82 has a first bracket portion 83 on one side and a second bracket portion 84 on the other side along the center line Cx. The first bracket portion 83 and the second bracket portion 84 are integrally formed.

[0076] The first support portion 83 has a side wall 831 orthogonal to the center line Cx. A bottom wall 832 is provided at the lower end of the side wall 831. The bottom wall 832 extends in the direction of the center line Cx, in a direction separate from the second support portion 84. One side surface 832a and the other side surface 832b of the bottom wall 832 in the thickness direction are flat surfaces parallel to the center line Cx.

[0077] Ribs 838 and 839 are provided across the side wall 831 and the bottom wall 832.

[0078] like Figure 5 As shown in (a), ribs 838 and 839 are spaced apart on a straight line Ly parallel to the diameter line Cy. Each rib 838 and 839 has an inclined surface formed by a straight line connecting the upper end of the side wall 831 to the front end of the bottom wall 832. In side view, ribs 838 and 839 form approximately right-angled triangles (see reference). Figure 3 (b)).

[0079] The upper surface 832a of the bottom wall 832 is divided into three regions (833a, 834a, 835a) by ribs 838 and 839. Through holes 833b, 834b, and 835b, which penetrate the bottom wall 832 in the thickness direction, open in each region. The through holes 833b, 834b, and 835b are respectively located at positions intersecting the straight line Ly.

[0080] Here, in the first support portion 83, a countersunk portion 836 is formed at the area where the upper end of the side wall 831 intersects with the rib 839. A screw hole 836b opens on the countersunk surface (seat surface) 836a of the countersunk portion 836. The screw hole 836b is formed on the extension line of the rib 839 in the straight line Lx direction parallel to the center line Cx (see reference). Figure 5 (a)).

[0081] The second support portion 84 extends from the side 831a of the side wall 831 opposite to the ribs 838 and 839. The second support portion 84 extends from the upper end of the side wall 831 of the first support portion 83 (see reference). Figure 3 (a)).

[0082] The second support portion 84 is a plate-shaped member extending along the centerline Cx in a direction separate from the first support portion 83. The length of the second support portion 84 in the direction of the centerline Cx is slightly longer than the length of the base 80 of the mounting member 8L and the elastic member 81.

[0083] With the second bracket portion 84 embedded in the elastic member 81, the first bracket portion 83 is exposed inside the engine compartment R. Furthermore, the first bracket portion 83 and the transmission housing 2 (side cover 3, housing 4) are positioned in the following manner.

[0084] (i) The bottom wall 832 of the first support portion 83 coincides with the upper part of the protrusion 35 of the side cover 3 (see reference). Figure 2 , Figure 3 ).

[0085] (ii) The front end face 411a of the boss portion 411 of the housing 4 is flush with the countersunk surface 836a of the countersunk head 836 of the first support portion 83 (see reference). Figure 3 (a)).

[0086] (iii) The center of the screw hole 411b of the boss portion 411, the center of the screw hole 836b of the countersunk head 836, and the rib 839 are located on the same straight line Lx (see reference). Figure 3 (b)).

[0087] In the positional relationship described above (i), the upper surfaces 351a, 352a, and 353a of the protrusions 351, 352, and 353 (refer to...) Figure 1 The lower surface 832b of the bottom wall 832 of the first support portion 83 abuts against the surface of the support portion 83, which covers approximately the entire surface (see reference). Figure 3 (a)). Screw holes 351b, 352b, and 353b of protrusions 351, 352, and 353 (refer to) Figure 1 ) and the through holes 833b, 834b, 835b of the bottom wall 832 (refer to Figure 5 (b) They overlap one-to-one respectively.

[0088] That is, by screwing bolts B, which pass through holes 833b, 834b, and 835b on the side of the fixing bracket 82, into the screw holes 351b, 352b, and 353b of the protrusions 351, 352, and 353 on the side of the side cover 3, respectively, the side cover 3 is connected to the fixing bracket 82.

[0089] In the positional relationships described in (ii) and (iii) above, the support plate member 9 abuts against the front end face 411a of the boss portion 411 and the countersunk surface 836a of the countersunk head 836d, covering the entire surface.

[0090] The support plate component 9 is suspended from the housing 4 and the fixed bracket 82 via bolts B screwed into the screw holes 411b and 836b.

[0091] [Support plate component 9]

[0092] like Figure 6As shown in (a), the strip-shaped support plate member 9 has the same thickness T along its entire length in the long side direction. One side of the support plate member 9 in the thickness direction and the other side form flat surfaces orthogonal to the thickness direction.

[0093] like Figure 6 As shown in (b), curved surfaces are applied to one end 9a and the other end 9b of the support plate component 9 along its long side. The outer periphery 91 of one end 9a and the outer periphery 92 of the other end 9b of the support plate component 9 are formed into approximately arc shapes such that the centers P1 and P2 are located on a straight line Lp passing through the middle of the width direction of the support plate component 9.

[0094] Through holes 98 and 99 are formed in the support plate component 9 in the thickness direction. The center of the through holes 98 and 99 coincides with the center of the arc P1 and P2.

[0095] The interval L3 between the through holes 98 and 99 in the straight line Lp direction and the screw hole 411b of the boss portion 411 in the straight line Lx direction (refer to) Figure 3 (b) and the screw hole 836b of the countersunk surface 836a (refer to) Figure 3 (b)) The intervals are the same.

[0096] Here, as described above, the front end face 411a of the boss portion 411 (refer to...) Figure 3 (a) and the countersunk surface 836a of the countersunk head 836 (refer to) Figure 3 (a) Flush configuration. Furthermore, the center of the screw hole 411b of the boss portion 411 and the center of the screw hole 836b of the countersunk head 836 are located on the same straight line Lx (refer to...). Figure 3 (b)) Above.

[0097] like Figure 3 As shown in (a), the support plate member 9 is positioned across the front end face 411a of the boss portion 411 and the countersunk surface 836a of the countersunk head 836 of the fixed bracket 82. In this state, the long side direction (straight line Lp) of the support plate member 9 is aligned with the straight line Lx (see reference). Figure 3 (b) The through holes 98 and 99 of the support plate component 9 coincide with the screw holes 411b of the boss portion 411 and the screw holes 836b of the countersunk head 836, respectively.

[0098] Thus, the support plate component 9 is suspended from the housing 4 and the fixed bracket 82 via bolts B screwed into the screw holes 411b and 836b.

[0099] like Figure 3 As shown in (a), the first bracket portion 83 on one side of the center line Cx direction of the fixed bracket 82 is directly fixed to the protrusion 35 of the side cover 3, and is indirectly fixed to the housing 4 via the support plate member 9.

[0100] In addition, the second bracket portion 84 on the other side of the center line Cx direction is inserted into the elastic member 81 housed in the cylindrical base 80 of the mounting member 8L, and the second bracket portion 84 is mounted on the side beam 6L via the mounting member 8L.

[0101] Here, the centerline Cx of the base 80 is aligned with the long side of the side beam 6L (straight line Lm1: reference). Figure 3 (b) Orthogonal.

[0102] Furthermore, the support plate component 9 is suspended from the first bracket portion 83 and the housing 4 in the direction of the straight line Lx parallel to the center line Cx. That is, the long side direction of the support plate component 9 is orthogonal to the long side direction (straight line Lm1) of the side beam 6L.

[0103] As described above, the fixing bracket 82 is fixed to the protrusion 35 on the side of the side cover 3 by three bolts B. The fixing bracket 82 and the side cover 3 are fastened to three points by the bolts B. These three points are set at intervals in the longitudinal direction of the vehicle V.

[0104] Furthermore, in this embodiment, the fixed bracket 82 is also fixed to the housing 4 via the support plate component 9, and the fixed bracket 82 and the housing 4 are fastened to a single point by bolt B.

[0105] Both the side cover 3 and the housing 4 are structural components of the transmission housing 2. In this embodiment, the fixing bracket 82 and the fastening points on the side of the transmission housing 2 total four points.

[0106] Furthermore, the fastening points (three points) with the side cover 3 and the fastening point (one point) with the housing 4 are set at intervals in the straight line Lx direction (the vehicle width direction in this embodiment).

[0107] Therefore, the rigidity of the support structure of the transmission housing 2 is improved through the following actions.

[0108] (a) The side cover 3 and housing 4, which have different natural frequencies, are integrally connected with the fixed bracket 82, thereby increasing the overall natural frequency of the transmission housing 2.

[0109] (b) The fastening points (three points) with the side cover 3 and the fastening point (one point) with the housing 4 are set at intervals in the vehicle width direction, thereby improving the rigidity against vibrations in the vehicle width direction (vibrations in the left and right directions of vehicle reversal).

[0110] The support plate component 9 is suspended between the boss portion 411 and the first bracket portion 83 with its long side direction aligned with the straight line Lx direction.

[0111] Here, rib 413 is located on the opposite side of the support plate member 9, which is separated from the boss portion 411, in the straight line Lx direction. Rib 413 is provided along the straight line Ln2 direction (see reference). Figure 4 (b)). In this state, when viewed from above and below, lines Ln2 and Lx are aligned on a straight line (see reference). Figure 3 (b)).

[0112] Therefore, rib 413 extends in the direction of the long side of the support plate member 9 (refer to...). Figure 5 (b)).

[0113] As a result, the rigidity of the support plate component 9 in the long side direction is further improved, which can firmly resist vibration in that direction.

[0114] [Wire Harness H]

[0115] Figure 7 This is a diagram illustrating the configuration of wire harness H. Figure 7 (a) explains how to lay the wire harness H in Figure 2 (a) is a diagram showing the state of the transmission housing 2. Figure 7 (b) is a schematic representation Figure 7 (a) is a diagram of the DD section.

[0116] like Figure 7 As shown in (a), a wire harness H is laid on the upper surface of the side cover 3 and the housing 4. The wire harness H is arranged to pass through the rib 413.

[0117] In this embodiment, such as Figure 7 As shown in (b), the protrusion height h2 of the region on the side of the boss portion 411 of the rib 413 is set to be lower than the protrusion height h1 of other regions (h1 > h2).

[0118] Here, when there is no lower section in rib 413, the wire harness H needs to be arranged to extend beyond rib 413 in the part that overlaps with rib 413. Thus, the total length of wire harness H needs to be increased by the length extending beyond rib 413.

[0119] In contrast, in this embodiment, by reducing the protrusion height of the rib 413 on the side of the boss portion 411, the wire harness H passes through the lower-height portion, thereby preventing the overall length of the wire harness H from increasing.

[0120] The vehicle V having the continuously variable transmission 1 of this embodiment has the following structure.

[0121] (1) It has a transmission housing 2 (housing component) which is supported on the side beam 6L (frame) of the vehicle body via mounting component 8L.

[0122] It has a support plate component 9, which is suspended from the boss portion 411 of the housing 4 of the transmission housing 2, and a fixing bracket 82 (a component on the housing component side) for mounting component 8L.

[0123] The straight line Lx along the long side of the support plate component 9 intersects the straight line Lm1 along the long side of the side beam 6L.

[0124] The root 411c of the boss portion 411 has a rib 413 extending in the direction of the long side of the support plate member 9.

[0125] The support structure on the transmission housing 2 side of the mounting component 8L contributes to rigidity. Therefore, as described above, rigidity is improved by providing the support plate component 9. Furthermore, by making the long side direction of the support plate component 9 intersect the long side direction of the side beam 6L, rigidity in that direction can be improved. Moreover, by providing a rib 413 extending in the direction extending along the long side direction of the support plate component 9 at the root 411c of the boss portion 411, the support rigidity in the long side direction of the support plate component 9 can be further improved, and a robust support structure can be constructed to resist vibration in that direction.

[0126] The vehicle V having the continuously variable transmission 1 of this embodiment has the following structure.

[0127] (2) The transmission housing 2 includes: housing 4 (main housing component) and side cover 3 (cover component) connected to housing 4.

[0128] The mounting bracket 82 of the mounting component 8L is supported on the side cover 3, and the boss 411 and rib 413 are formed in the housing 4.

[0129] In order not to increase the size of the mounting component 8L, the fixing bracket 82 on the transmission housing 2 side of the mounting component 8L is preferably positioned on the side close to the mounting component 8L. Therefore, the fixing bracket 82 is preferably connected to the side cover 3 and supported on the side cover 3.

[0130] On the other hand, the space for the side cover 3 side suspension support plate component 9 and the space for the configuration ribs are insufficient, and the size of the side cover will increase when trying to make room.

[0131] Therefore, by configuring the boss 411 and rib 413 as described above in the housing 4 that occupies the space, and by supporting the fixing bracket 82 on the side cover 3, a high support rigidity can be ensured without increasing the size of the mounting component 8L.

[0132] The vehicle V having the continuously variable transmission 1 of this embodiment has the following structure.

[0133] (3) The fixed bracket 82 is connected to the transmission housing 2 by multiple bolts B (fasteners).

[0134] Multiple bolts B are configured to overlap each other along the straight line Ly direction (the direction that intersects the long side direction of the support plate component 9).

[0135] When multiple bolts B are configured to not overlap in one direction (e.g., a neat triangular configuration), the rigidity of the side beam 6L can be improved in both the long side direction and the direction intersecting it, but the shape will increase in the direction intersecting the long side direction of the side beam 6L.

[0136] Therefore, by configuring it as described above, in the direction intersecting the long side direction of the support plate member 9, multiple bolts B are used to ensure rigidity in that direction, and in the long side direction of the support plate member 9, the support plate member 9 is used to ensure rigidity, thereby achieving both improved rigidity and suppression of increased size.

[0137] The vehicle V having the continuously variable transmission 1 of this embodiment has the following structure.

[0138] (4) The wire harness H is positioned above the rib 413.

[0139] The height h2 of the rib 413 in the region overlapping with the wire harness H is set lower than the height h1 of the rib in the region adjacent to the region overlapping with the wire harness H.

[0140] With this configuration, although the rib 413 is higher when the wire harness H crosses the rib 413, requiring the wire harness H to be longer accordingly, this can be appropriately avoided.

[0141] The above describes the embodiments of the present invention, but the present invention is not limited to the embodiments shown therein, and appropriate changes can be made within the scope of the technical concept of the invention.
