Summary of the Invention

Problems to be Solved by the Invention

[0004] On the upper surface of the air cleaner, it is relatively easy to secure a relatively large plane for installing electrical components such as the ECM, but it is difficult to satisfy the vibration resistance guarantee value of the electrical components due to the transmission of vibration from the engine. In addition, a straddle-type vehicle also generates large vibrations due to rough road surfaces or jump driving. Although the influence of large vibrations can be suppressed by rigid fixing or tight fixing of the electrical components, there is a problem that fine vibrations from the engine are easily transmitted to the electrical components.

[0005] The present invention has been made in view of this point, and an object thereof is to provide an installation structure of an electrical component that can suppress the influence not only of engine vibration but also of vibrations larger than engine vibration on the electrical component installed on the air cleaner. [Means for solving the problem]

[0006] An electrical component installation structure according to one aspect of the present invention comprises an air cleaner connected to the engine of a saddle-type vehicle, an electrical component supported from below by the air cleaner, a cover member that covers the upper part of the electrical component with a gap, a first cushion sandwiched between the cover member and the electrical component, and a second cushion sandwiched between the air cleaner and the electrical component, wherein the cover member is provided with a restricting portion that restricts the displacement of the electrical component when vibrations greater than engine vibrations occur, thereby solving the above problem. [Effects of the Invention]

[0007] According to one embodiment of the present invention, the electrical component is suspended and fixed between the cover member and the air cleaner via first and second cushions. Engine vibrations are absorbed by the first and second cushions, suppressing the effect of engine vibrations on the electrical component. When vibrations greater than engine vibrations occur, the displacement of the electrical component is restricted by the restricting portion of the cover member, and the acceleration of the electrical component is reduced by the deformation of the first and second cushions, mitigating the impact on the electrical component. In this way, the effects of engine vibrations and vibrations greater than engine vibrations on the electrical component are suppressed. [Brief explanation of the drawing]

[0009] In one embodiment of the present invention, an air cleaner is connected to the engine. Electrical components are supported from below by the air cleaner, and the electrical components are covered by a cover member with a gap above them. A first cushion is sandwiched between the cover member and the electrical components, and a second cushion is sandwiched between the air cleaner and the electrical components, so that the electrical components are suspended and fixed between the cover member and the air cleaner via the first and second cushions. Engine vibrations are absorbed by the first and second cushions, suppressing the effect of engine vibrations on the electrical components. Furthermore, the cover member has a restricting portion that restricts the displacement of the electrical components when vibrations greater than engine vibrations occur, and the displacement of the electrical components is restricted by the restricting portion of the cover member, and the acceleration of the electrical components is reduced by the deformation of the first and second cushions, mitigating the impact on the electrical components. In this way, the effect of engine vibrations and vibrations greater than engine vibrations on the electrical components is suppressed. [Examples]

[0010] The saddle-type vehicle of this embodiment will be described below with reference to the attached drawings. Figure 1 is a left side view of the saddle-type vehicle of this embodiment. In the following figures, arrow Fr indicates the front of the vehicle, arrow Re indicates the rear of the vehicle, arrow L indicates the left side of the vehicle, and arrow R indicates the right side of the vehicle.

[0011] As shown in Figure 1, the saddle-type vehicle 1 is constructed by mounting various components such as the engine 41 and electrical systems on a vehicle frame 10. A pair of tank rails 12 extend diagonally downward and to the rear from the head pipe 11 of the vehicle frame 10, and a pair of body frames 13 extend downward from the rear of the pair of tank rails 12. In addition, a down frame 14 extends downward from the head pipe 11, and a rearward-bent under loop 15 is connected to the lower part of the down frame 14. The rear end of the under loop 15 is connected to the lower part of the pair of body frames 13, so that the vehicle frame 10 is formed in a cradle shape.

[0012] The front fork 21 is supported by the head pipe 11 via a steering shaft (not shown) so as to be steerable. A handlebar 22 is provided on the upper part of the front fork 21, and the front wheel 23 is rotatably supported on the lower part of the front fork 21. A fuel tank (not shown) is placed over a pair of tank rails 12, and the pair of tank rails 12 and the fuel tank are covered by a tank cover 24 and a pair of front side covers 25. A seat 27 is installed behind the tank cover 24, and seat rails 16 and 17 (see Figure 2) that support the seat 27 from below are covered from the side by a pair of rear side covers 26.

[0013] A swingarm 31 is pivotably supported on the body frame 13. The swingarm 31 extends rearward from the body frame 13, and a rear wheel 32 is rotatably supported at the rear end of the swingarm 31. The front of the swingarm 31 and the lower part of the rear suspension 33 are connected via a cushion lever 34. The cushion lever 34 and the body frame 13 are also connected via a cushion rod 35. As the swingarm 31 pivots, the rear suspension 33 expands and contracts, absorbing road surface irregularities and suppressing vibrations, while also improving the contact between the road surface and the rear wheel 32.

[0014] The engine 41 is a single-cylinder engine and is suspended inside the vehicle frame 10 via suspension brackets 36-38. A cylinder assembly, consisting of a cylinder 43, cylinder head 44, and cylinder head cover 45, is mounted on the upper surface of the crankcase 42 of the engine 41. An exhaust pipe 46 is connected to the front of the cylinder head 44. The exhaust pipe 46 extends to the rear, passing to the right of the cylinder 43, and an upward-sloping muffler 47 is connected to the downstream side of the exhaust pipe 46. An intake device, such as an air cleaner 50, is installed behind the cylinder head 44.

[0015] Incidentally, the ECM (Electronic Control Module) is sometimes installed on top of the air cleaner as an electrical component. When installing an ECM in a saddle-type vehicle, the mounting location and structure must be considered to meet the vibration resistance guarantee value of the ECM. If there are few on-board components, the ECM can be installed in a place with low vibration via a rubber holder or the like, but the installation space is limited due to the enlargement of ECMs and the increase in auxiliary equipment in response to recent exhaust gas regulations and the addition of functions. The top of the air cleaner can secure a relatively large flat surface, but the intake pulsation of the air cleaner and fine engine vibrations of 50 Hz or higher may exceed the vibration resistance guarantee value of the ECM.

[0016] Furthermore, rough road surfaces and jump driving frequently generate large vibrations below 50 Hz. While rigid fixing of the ECM or tight fixing using rubber holders is effective against large vibrations, these fixing methods make it easier for engine vibrations above 50 Hz to be transmitted to the ECM. Moreover, when rubber holders are tightened, the flexibility of the rubber is lost, and the vibration absorption effect is greatly reduced. Thus, in saddle-type vehicles, not only engine vibrations above 50 Hz but also vibrations below 50 Hz due to jump driving and other factors are transmitted to the ECM, and it is necessary to suppress the effects of both types of vibrations on the ECM.

[0017] Here, the displacement of the ECM due to vibrations below 50 Hz, such as those caused by jump driving, is greater than the displacement of the ECM due to engine vibrations above 50 Hz. For example, the displacement of the ECM due to engine vibration is approximately 0.4 mm, while the displacement of the ECM due to vibrations during jump landing is approximately 4.75 mm. Therefore, in this embodiment, the effect of engine vibration on the ECM is suppressed by floating and fixing the ECM via a cushion above the air cleaner. Furthermore, by restricting the displacement of the floating and fixed ECM to a minimum, the effect of vibrations greater than engine vibration on the ECM is suppressed.

[0018] Referring to FIGS. 2 to 4, the air cleaner of this embodiment will be described. FIG. 2 is a top view of the periphery of the air cleaner of this embodiment. FIG. 3 is a perspective view of the periphery of the air cleaner of this embodiment. FIG. 4 is a perspective view of the air cleaner of this embodiment. In FIGS. 2 and 3, the state where the seat is removed from the vehicle body frame is shown.

[0019] As shown in FIGS. 2 and 3, a pair of upper seat rails 16 extend rearward from the upper part of the pair of body frames 13, and a pair of lower seat rails 17 extend obliquely upward rearward from the lower part of the pair of body frames 13. The rear ends of the pair of lower seat rails 17 are connected to the rear ends of the pair of upper seat rails 16. Also, the rear ends of the pair of upper seat rails 16 are connected via a seat bridge 18. In side view, the air cleaner 50 is installed in the triangular space surrounded by the body frame 13, the upper seat rail 16, and the lower seat rail 17 in side view.

[0020] An ECM 67 is installed as an electrical component on the upper surface of the cleaner case 51 of the air cleaner 50. The front side of the ECM 67 bulges upward, and a pair of connector parts 68 are provided on this bulging part 70. The periphery of the bulging part 70 is pressed from above by a lid (cover member) 71 having a U-shaped view from above. The front side of the bifurcated lid 71 is fixed to the upper surface of the air cleaner 50 by a pair of bolts 83, and the rear side of the lid 71 is fixed to the seat bridge 18 by a pair of clips 84. The rear side of the lid 71 is lower by one step between the bulging part 70 and the seat bridge 18, and holding claws 78 and a holder 79 for holding a tool 85 are formed in the depression of this lid 71.

[0021] An inlet tube 55 (see Figure 4) is provided on the rear upper surface of the cleaner case 51, and an outlet tube 61 is provided on the front side of the cleaner case 51. A filter (not shown) is installed inside the cleaner case 51, and air taken in from the inlet tube 55 is filtered by the filter and sent to the outlet tube 61. The outlet tube 61 is connected to the engine 41 via an electronically controlled throttle 87 and an intake pipe 88. Air is sent from the outlet tube 61 to the electronically controlled throttle 87, and after the intake volume is adjusted by the electronically controlled throttle 87, the air is supplied to the engine 41 through the intake pipe 88.

[0022] As shown in Figures 3 and 4, the air cleaner 50 is constructed by sandwiching a separator plate 64 between the dirty-side cleaner case 51 and the clean-side outlet tube 61. The cleaner case 51 is formed in the shape of a triangular box when viewed from the side, with an open front, and a filter is installed inside the cleaner case 51. A work window (not shown) is formed on the left side of the cleaner case 51, and a side cap 65 is detachably attached to the work window. The filter inside the cleaner case 51 can be replaced periodically by removing the side cap 65 from the cleaner case 51.

[0023] The upstream side of the outlet tube 61 is a chamber section 62 connected to the cleaner case 51, and the downstream side of the outlet tube 61 is a passage section 63 leading to the engine 41 (see Figure 2). The chamber section 62 curves to the left as it moves forward to avoid the rear suspension 33 (see Figure 1), and a cylindrical passage section 63 protrudes forward from the front end of the chamber section 62. The separate plate 64 forms the front wall of the cleaner case 51, and an opening (not shown) is formed in the center of the separate plate 64 that connects the intake chamber in the cleaner case 51 and the intake passage in the outlet tube 61.

[0024] As described above, the ECM 67 is supported from below by the cleaner case 51. In this case, the top surface of the cleaner case 51 is recessed, forming a recess 52 and a pair of bulging walls 53. The pair of bulging walls 53 face each other across the recess 52, and the ECM 67 is supported from both sides by the pair of bulging walls 53. The front and both sides of the recess 52 are closed by the walls, while the top and rear of the recess 52 are open. An inlet tube 55 is inserted into the bottom surface of the recess 52, with the intake port of the inlet tube 55 facing upward. The intake port of the inlet tube 55 is covered from above by the ECM 67, preventing foreign matter from entering the intake port.

[0025] The ECM67 has a thin, rectangular plate-shaped case 69, a bulge 70 that protrudes from the front upper surface of the plate-shaped case 69, and a pair of connector sections 68 provided on the front of the bulge 70. A circuit board is housed inside the plate-shaped case 69, and various electronic components such as a processor and memory are mounted on the circuit board. The plate-shaped case 69 is made up of two sections, upper and lower, with the lower section being wider in the vehicle width direction than the upper section. The bulge 70 protrudes upward from the front of the plate-shaped case 69, and the mounting openings of the pair of connector sections 68 are oriented forward. A harness (not shown) extending from an external device is connected to the pair of connector sections 68 from the front.

[0026] With a gap between the ECM67 and the lid 71, the top of the ECM67 is covered by the lid 71. The lid 71 is formed in a U-shape when viewed from above by a pair of vertical frame sections 72 on both sides of the bulge 70 and a horizontal frame section 73 at the rear of the bulge 70. The tips of the pair of vertical frame sections 72 are fixed to a pair of bosses 54 on the cleaner case 51 with bolts 83, and a rear plate 74 rising from the rear edge of the horizontal frame section 73 is fixed to the front of the seat bridge 18 with clips 84. A pair of side plates 75 rising from the outer edges of the pair of vertical frame sections 72 are in contact with both sides of the upper part of the plate-shaped case 69, and the inclined portion 76 of the front edge of the horizontal frame section 73 covers the rising portion of the bulge 70.

[0027] Three upper cushions (first cushions) 81 are sandwiched between the lid 71 and the ECM 67. Two of the upper cushions 81 extend in the front-rear direction, and these upper cushions 81 are interposed between a pair of vertical frame sections 72 and the ECM 67. One upper cushion 81 extends in the vehicle width direction, and this upper cushion 81 is interposed between the inclined portion 76 of the front edge of the horizontal frame section 73 and the ECM 67 (see Figure 6). A tool holder 79 for the tool 85 is provided in the recess of the lid 71, and the upper cushions 81 are installed in three locations avoiding this recess of the lid 71. The upper cushions 81 are formed of foamed rubber cushions with a thickness of 10 [mm], such as EPT Sealer (registered trademark).

[0028] A pair of lower cushions (second cushions) 82 are sandwiched between the air cleaner 50 and the ECM 67. The pair of lower cushions 82 extend in the front-rear direction, and these lower cushions 82 are interposed between the pair of bulging walls 53 and the ECM 67. The lower cushions 82 are made of, for example, 3 mm thick foamed polyolefin foam such as P·E-Lite (registered trademark), or 3 mm thick polyethylene foam such as EVA foam. In this way, the ECM 67 is suspended and fixed between the lid 71 and the air cleaner 50 by the upper cushion 81 and the lower cushion 82.

[0029] Fine engine vibrations are absorbed by the upper cushion 81 and lower cushion 82, suppressing the effect of engine vibrations on the ECM 67. In addition, restricting portions 77 are formed on the lower side of the pair of side plates 75 of the lid 71, and the lower part of the ECM 67 protrudes in a flange-like manner below the pair of restricting portions 77. The pair of restricting portions 77 face the lower part of the ECM 67 with a gap in the vertical direction. When vibrations larger than engine vibrations occur due to jump driving, etc., the pair of restricting portions 77 abut against the lower part of the ECM 67, restricting the displacement of the ECM 67 and suppressing the effect of large vibrations on the ECM 67.

[0030] The detailed configuration of the ECM installation structure will be described with reference to Figures 5 and 6. Figure 5 is a rear view of the area around the ECM in this embodiment. Figure 6 is a top view of the area around the ECM in this embodiment.

[0031] As shown in Figure 5, the ECM 67 is supported from below by a pair of lower cushions 82 on a pair of bulging walls 53 of the cleaner case 51. The lower cushions 82 are formed to be relatively thin, and the ECM 67 is positioned slightly higher than the upper surface of the pair of bulging walls 53. The ECM 67 is pressed down from above by the lid 71 on three upper cushions 81. The upper cushions 81 are formed to be relatively thick, and a sufficient gap is left between the lid 71 and the ECM 67. A pair of side plates 75 of the lid 71 extend along the sides of the upper part of the ECM 67, and the lower restricting portions 77 of the pair of side plates 75 face the lower part of the ECM 67 with a gap C between them.

[0032] A gap is provided between the pair of restricting parts 77 and the ECM67 that is greater than the displacement of the ECM67 due to engine vibration, and smaller than the displacement of the ECM67 due to vibrations greater than engine vibration. For example, the displacement of the ECM67 is 0.4 mm when the engine vibration is 50 Hz or higher, and the displacement of the ECM67 is 4.75 mm when the vibration greater than engine vibration is less than 50 Hz. Therefore, for example, a gap greater than 0.4 mm and smaller than 4.75 mm is provided between the pair of restricting parts 77 and the ECM67.

[0033] During normal driving, engine vibrations are transmitted from the pair of bulging walls 53 of the cleaner case 51 to the ECM 67 via the lower cushion 82, and also from the cleaner case 51 to the ECM 67 via the lid 71 and upper cushion 81. Since the pair of restricting parts 77 do not come into contact with the ECM 67 during engine vibration, engine vibrations are not directly transmitted from the lid 71 to the ECM 67. Because engine vibrations are transmitted from the air cleaner 50 and lid 71 to the ECM 67 via the lower cushion 82 and upper cushion 81, a high vibration isolation effect can be obtained from the lower cushion 82 and upper cushion 81.

[0034] During jump driving, vibrations greater than engine vibrations are generated. These vibrations are transmitted from the cleaner case 51 (see Figure 4) to the ECM 67 via a pair of bulging walls 53 and the lid 71. At this time, the contact between the pair of restricting parts 77 of the lid 71 and the lower part of the ECM 67 suppresses the displacement of the ECM 67, thereby reducing the impact on the ECM 67. In particular, if the gap between the pair of restricting parts 77 and the ECM 67 is made slightly larger than the amount of displacement of the ECM 67 due to engine vibration, the impact on the ECM 67 is effectively mitigated. Furthermore, the deformation of the lower cushion 82 and the upper cushion 81 also mitigates the impact on the ECM 67.

[0035] The upper surface of the ECM 67 is formed in a stepped (convex) shape so that it fits into a pair of side plates 75 of the lid 71. The opposing surfaces of the pair of side plates 75 are in contact with both sides of the upper stepped portion of the ECM 67, suppressing rattle in the vehicle width direction of the ECM 67 when vibrations greater than engine vibrations occur. Furthermore, even if the ECM 67 is floating and fixed to the air cleaner 50, the ECM 67 is positioned relative to the air cleaner 50. The rattle of the ECM 67 in the front-to-back direction is suppressed by the contact between the upper cushion 81 on the back side of the inclined portion 76 of the lid 71 and the bulge portion 70, and by the connection between the pair of connector portions 68 and the harness.

[0036] The vertical distance between the lid 71 and the ECM 67 is greater than the vertical distance between the cleaner case 51 and the ECM 67. Sufficient height space is secured above the ECM 67, and by selecting the material of the upper cushion 81 according to the vehicle vibration, the amount of compression of the upper cushion 81 is adjusted, thereby suppressing vibration and shock. The space below the ECM 67 is narrowed, bringing the ECM 67 closer to the air cleaner 50. Furthermore, the lower cushion 82 is formed to be harder than the upper cushion 81. With these configurations, the ECM 67 is stably installed on the lower cushion 82.

[0037] Both sides of the ECM67 are supported by a pair of bulging walls 53 of the cleaner case 51, but the central part of the ECM67 is positioned in a recess 52 of the pair of bulging walls 53 and does not come into contact with the cleaner case 51. This reduces the contact area between the ECM67 and the pair of bulging walls 53, thereby suppressing engine vibrations transmitted from the air cleaner 50 to the ECM67. In addition, the area of ​​the lower cushion 82 attached to the cleaner case 51 is reduced, which lowers costs. The ECM67 is installed using the upper surface of the pair of bulging walls 53, and the ECM67 also functions as a hood for the suction port of the inlet tube 55 (see Figure 4).

[0038] A pair of upper cushions 81 are installed spaced apart along the longitudinal direction of the ECM 67, and the lid 71 is recessed between the pair of upper cushions 81. A holder 79 and retaining claws 78 are provided in the recess 89 of the lid 71, and a tool 85 (see Figure 2) can be installed on the holder 79 and retaining claws 78. The end of the tool 85 fits inside the holder 79, and the middle part of the tool 85 is hooked onto the retaining claws 78. The rigidity of the lid 71 is increased without increasing the thickness of the lid 71 by using the recess 89 of the lid 71 and the installation of the tool 85. In addition, the tool 85 can be installed by utilizing the space between the pair of upper cushions 81.

[0039] As described above, with the air cleaner 50 of this embodiment, the ECM 67 is suspended and fixed between the lid 71 and the air cleaner 50 via the upper cushion 81 and the lower cushion 82. Engine vibrations are absorbed by the upper cushion 81 and the lower cushion 82, suppressing the effect of engine vibrations on the ECM 67. When vibrations greater than engine vibrations occur, the displacement of the ECM 67 is restricted by the restricting portion 77 of the lid 71, and the acceleration of the ECM 67 is reduced by the deformation of the upper cushion 81 and the lower cushion 82, thereby mitigating the impact on the ECM 67. In this way, the effects of engine vibrations and vibrations greater than engine vibrations on the ECM 67 are suppressed.

[0040] In this embodiment, an ECM was used as an example of an electrical component, but other electrical components such as a CDI (Capacitive Discharge Ignition) may also be used.

[0041] Furthermore, in this embodiment, a lid with a U-shaped top view is provided as the cover member, but the shape of the cover member is not particularly limited as long as it is formed to cover the top of the electrical components with a gap.

[0042] In this embodiment, three upper cushions are sandwiched between the lid and the ECM, but the number and shape of the upper cushions are not particularly limited.

[0043] In this embodiment, a pair of lower cushions are sandwiched between the air cleaner and the ECM, but the number and shape of the lower cushions are not particularly limited.

[0044] In this embodiment, the upper cushion is formed to be thicker than the lower cushion, but the lower cushion may be formed to be thicker than the upper cushion, or the lower cushion and the upper cushion may be formed to be the same thickness.

[0045] Furthermore, in this embodiment, the lower cushion is formed to be harder than the upper cushion, but the upper cushion may be formed to be harder than the lower cushion, or the lower and upper cushions may be formed to be the same hardness.

[0046] Furthermore, the electrical component mounting structure of this embodiment is not limited to the above-described saddle-type vehicle, but may be adopted in other types of saddle-type vehicles as well. Note that the term "saddle-type vehicle" is not limited to all vehicles in which the driver sits straddling a seat, but also includes scooter-type vehicles in which the driver does not straddle a seat.

[0047] As described above, the first embodiment comprises an air cleaner (50) connected to the engine (41) of a saddle-type vehicle (1), an electrical component (ECM67) supported from below by the air cleaner, a cover member (lid 71) that covers the top of the electrical component with a gap, a first cushion (upper cushion 81) sandwiched between the cover member and the electrical component, and a second cushion (lower cushion 82) sandwiched between the air cleaner and the electrical component. The cover member has a restricting portion (77) formed therein that restricts the displacement of the electrical component when vibrations greater than engine vibrations occur. With this configuration, the electrical component is suspended and fixed between the cover member and the air cleaner via the first and second cushions. Engine vibrations are absorbed by the first and second cushions, and the effect of engine vibrations on the electrical component is suppressed. When vibrations greater than engine vibrations occur, the displacement of electrical components is restricted by the restricting portion of the cover member, and the acceleration of the electrical components is reduced by the deformation of the first and second cushions, thereby mitigating the impact on the electrical components. In this way, the effects of engine vibrations and vibrations greater than engine vibrations on electrical components are suppressed.

[0048] In the second embodiment, as in the first embodiment, a gap larger than the displacement of the electrical component due to engine vibration is left between the restricting portion of the cover member and the electrical component. With this configuration, engine vibration is not directly transmitted from the cover member to the electrical component, and a high vibration isolation effect can be obtained from the first and second cushions. Furthermore, if the gap between the restricting portion and the electrical component is made slightly larger than the displacement of the electrical component due to engine vibration, the impact applied to the electrical component is effectively mitigated.

[0049] The third aspect is that, in the first or second aspect, the engine vibration is a vibration of 50 Hz or higher, and the vibration that is greater than the engine vibration is a vibration of less than 50 Hz. With this configuration, the effects of relatively fine vibrations of 50 Hz or higher and relatively large vibrations of less than 50 Hz on electrical components can be suppressed.

[0050] The fourth embodiment is one of the first to third embodiments, in which a pair of side plates (75) rise downward from both side edges of the cover member in the vehicle width direction, the upper surface of the electrical component is formed in a convex shape so as to fit into the pair of side plates, a restricting portion is formed at the lower end of the pair of side plates, and the opposing surfaces of the pair of side plates are in contact with the electrical component. With this configuration, the effects of engine vibration are suppressed, and rattling of the electrical component in the vehicle width direction when vibrations greater than engine vibration occur is suppressed. In addition, even if the electrical component is floatingly fixed to the air cleaner, the electrical component is positioned relative to the air cleaner.

[0051] The fifth embodiment is one of the first to fourth embodiments in which the distance between the cover member and the electrical component is greater than the distance between the air cleaner and the electrical component. With this configuration, sufficient height space is secured above the electrical component, and by selecting the material of the first cushion according to the vehicle vibration, the amount of compression of the first cushion is adjusted to suppress vibration and shock. The space below the electrical component is narrowed, bringing the electrical component closer to the air cleaner and allowing the electrical component to be installed stably.

[0052] The sixth embodiment is one of the first to fifth embodiments in which the second cushion is formed to be harder than the first cushion. With this configuration, electrical components can be stably installed on the second cushion.

[0053] The seventh embodiment is one of the first to sixth embodiments, in which the first cushion is a pair of first cushions spaced apart in the longitudinal direction of the electrical component, and the cover member is formed with a recessed area between the pair of first cushions, into which a tool (85) can be installed. With this configuration, rigidity can be increased without increasing the thickness of the cover member. A tool can be installed by utilizing the space between the pair of first cushions.

[0054] The eighth embodiment is one of the first to seventh embodiments, in which the upper surface of the air cleaner is recessed to form a recess (52) and a pair of bulging walls (53) flanking the recess, and electrical components are supported by the pair of bulging walls via a second cushion. With this configuration, the contact area between the electrical components and the air cleaner is reduced, thereby suppressing engine vibrations transmitted from the air cleaner to the electrical components. In addition, the contact area of ​​the second cushion attached to the air cleaner can be reduced.

[0055] Although this embodiment has been described, other embodiments may include combinations of the above embodiment and its modifications, either entirely or partially.
