Abstract
Description
[Technical field]
[0001] The present invention relates to a saddle-ride type vehicle. [Background technology]
[0002] Conventionally, there has been a saddle-type vehicle that includes an engine (internal combustion engine) mounted on the vehicle, a storage box disposed under the seat, a fuel tank for storing fuel to be supplied to the engine, and a canister for absorbing fuel evaporated in the fuel tank, in which the storage box and the fuel tank are arranged side by side in the longitudinal direction of the vehicle, a rear cross frame is disposed between the storage box and the fuel tank, and the canister is disposed along the rear cross frame so that the shape of the fuel tank is not restricted by the canister (see, for example, Patent Document 1). In this configuration, a stay is fixed to one of the left and right rear frames connected to the rear cross frame, and a purge control valve (purge control solenoid valve: PCSV) is attached to this stay. [Prior art documents] [Patent documents]
[0003] [Patent Document 1] JP 2013-189200 A Summary of the Invention [Problem to be solved by the invention]
[0004] However, in the above conventional technology, the PCSV is attached to the rear frame (vehicle body frame) via a stay, which increases the number of parts required to install a canister in the vehicle. Also, since the left and right rear frames are arranged to pass through the left and right outsides of the storage box, attaching the PCSV to the rear frames causes the area around the PCSV to protrude outward in the vehicle width direction.
[0005] The present invention has been made in consideration of the above circumstances, and has an object to mount a purge control valve in a saddle-ride type vehicle equipped with a canister purge control valve without increasing the number of parts and while minimizing protrusion in the vehicle width direction. [Means for solving the problem]
[0006] As a means for solving the above-mentioned problems, a first aspect of the present invention includes a seat (14) on which an occupant sits, a box body (16) arranged below the seat (14), an intake passage (23) arranged forward of the box body (16) in the vehicle longitudinal direction and connected to an internal combustion engine (E) mounted on the vehicle, a fuel tank (25) arranged rearward of the box body (16) and storing fuel to be supplied to the internal combustion engine (E), a canister (26) arranged so that at least a portion of the canister (26) overlaps with the fuel tank (25) in the vehicle longitudinal direction and adsorbs fuel evaporated in the fuel tank (25), and an intake passage (23) extending from the canister (26) toward the intake passage (23) and opening a flow path. In this saddle-type vehicle, one of the left and right outer portions (18L, 18R) of the box body (16) is configured as a purge component mounting portion (18b) for mounting a purge hose (43) of the purge passage (43A) and the purge control valve (27), and the purge component mounting portion (18b) is characterized in that it has a mounting recess (51) disposed on the upper rear side to enable mounting of the purge control valve (27), and a mounting groove portion (55) extending forward and downward from the mounting recess (51) to enable mounting of the purge hose (43). According to this configuration, the purge passage extends from the canister disposed toward the rear of the box body toward the intake passage forward of the box body, and one of the left and right outer parts of the box body is used as a purge parts mounting part for mounting the purge hose and the purge control valve of the purge passage. The purge parts mounting part is provided with a mounting recess for mounting the purge control valve at a high position on the upper rear side, and a mounting groove for mounting the purge hose extending forward and downward from the mounting recess, so that the purge control valve and the purge hose can be mounted on the outer part of the box body while suppressing the outward protrusion of the purge control valve and the purge hose in the vehicle width direction. Since the purge control valve and the purge hose are mounted using the mounting recess and mounting groove formed on the box body, a dedicated stay or the like is not required, the number of parts is reduced, and mounting is made easier, resulting in cost reduction. By mounting the purge control valve at a high position on the upper rear side of the purge parts mounting part, and extending the purge hose forward and downward from the purge control valve, the purge line is less likely to become a valley piping.
[0007] A second aspect of the present invention is characterized in that, in the above-mentioned first aspect, at least a portion of the mounting groove portion (55) in the groove length direction is provided with a retaining portion (56) that protrudes inwardly of the opening portion on the outer side of the vehicle width direction of the mounting groove portion (55) and restricts the purge hose (43) housed in the groove from coming off outward in the vehicle width direction. According to this configuration, by partially providing a retaining portion on the open side of the mounting groove that limits the removal of the purge hose housed within the groove, the purge hose can be easily and stably attached and the purge hose can be prevented from protruding outward in the vehicle width direction.
[0008] A third aspect of the present invention is characterized in that in the first or second aspect, a valve support portion (51b) for supporting the purge control valve (27) is integrally formed with the mounting recess (51). According to this configuration, the purge control valve is attached using the valve support portion formed in the mounting recess, eliminating the need for a separate stay, reducing the number of parts, making installation easier, and reducing costs.
[0009] A fourth aspect of the present invention is characterized in that, in the above-mentioned first or second aspect, the box body (16) forms an upper end opening (16a) that opens toward the top of the vehicle, the left and right outer portions (18L, 18R) of the box body (16) are provided with outer bulging portions (19L, 19R) that bulge outward in the vehicle width direction beyond the outer edge of the upper end opening (16a), and the purge component mounting portion (18b) has a mounting recess (51) formed on the upper rear side of the outer bulging portion (19L) and a mounting groove portion (55) formed along the outer surface of the outer bulging portion (19L). According to this configuration, by forming a mounting recess and a mounting groove using the outer bulge portions that bulge outward in the vehicle width direction on the left and right outer portions of the box body, it is possible to attach a purge control valve and a purge hose to the outer portion of the box body while minimizing the impact on the box capacity.
[0010] A fifth aspect of the present invention is characterized in that, in the above-mentioned first or second aspect, a bead portion (62) that bulges inwardly from the box is formed on the back side of the purge component mounting portion (18b) facing the inside of the box by forming a mounting groove portion (55) on the front side, at least a portion of the length of the bead portion (62) is provided with protrusions (63a, 63b) that protrude inwardly from the box, and the tips of the protrusions (63a, 63b) are provided with hook portions (61a, 61b) that engage a holding member (H1) that holds an article inside the box. According to this configuration, the hook portion that engages the item holding member inside the box is formed at the tip of the protrusion that protrudes further inward from the bead portion, thereby utilizing the bead portion on the back side of the mounting groove to increase the height of the protrusion, making it easier to engage the item holding member and reducing the height of the protrusion alone to reduce the amount of deformation.
[0011] A sixth aspect of the present invention is characterized in that, in the above-mentioned fifth aspect, the protrusions (63a, 63b) have a hollow shape in which a communicating space (63d) is formed to connect the inside and the outside of the box, and hook portions (61a, 61b) are formed so as to face the tip openings (63e) of the protrusions (63a, 63b) from the inside of the box. With this configuration, the protrusion is hollow to reduce weight, and by forming a hook portion facing the tip opening from the inside of the box, the hook portion that overhangs into the communication space when viewed from the protruding direction of the protrusion can be molded by splitting the mold along the protruding direction, which makes it easier to manufacture the box body.
[0012] A seventh aspect of the present invention is characterized in that in the sixth aspect, the base end openings (63f) of the projections (63a, 63b) are formed within the mounting groove portion (55). According to this configuration, by forming the base end opening of the protrusion within the mounting groove, the upper part of the mounting groove acts as a eave, and water, etc. flowing outside the box body can be prevented from entering the protrusion without the need for a separate eave shape, etc. In an eighth aspect of the present invention, in the first or second aspect, the mounting groove portion (55) extends at an incline so as to be positioned lower toward the front of the vehicle. According to this configuration, since the mounting groove extends at a downward incline toward the front, the purge hose held within the mounting groove is also arranged with the front downward. This makes it difficult for a valley shape to form in the purge passage, and allows the liquid flowing out from the canister side to flow into the intake passage without being trapped. Effect of the Invention
[0013] According to the present invention, in a saddle-type vehicle equipped with a purge control valve for a canister, the purge control valve can be mounted without increasing the number of parts and while minimizing protrusion in the vehicle width direction. [Brief description of the drawings]

Seat 14 is disposed above fuel tank 25 and storage box 16. Storage box 16 and fuel tank 25 are disposed side by side in the front-rear direction of the vehicle. Storage box 16 and fuel tank 25 are disposed in the front and the rear, respectively.
[0023] <Fuel Evaporation Circulation System> 7 is a schematic diagram of an evaporated fuel recirculation system according to an embodiment. As shown in the figure, the evaporated fuel recirculation system includes an engine (internal combustion engine) E, an intake passage 23 connected to the engine E, a pressure detector 24 provided in the intake passage 23 and detecting the intake pressure (negative pressure), a fuel tank 25 for storing fuel for the engine E, a canister 26 for recovering evaporated fuel from the fuel tank 25, a purge hose 43 connecting the intake passage 23 and the canister 26, a purge control solenoid valve 27 disposed in the middle of the purge hose 43 for controlling purge timing, and an electronic control device 28. Hereinafter, the purge control solenoid valve 27 may be referred to as "PCSV 27."
[0024] The engine E includes a crankcase 21 that houses a crankshaft 20, and a cylinder 22 that protrudes upward and forward from the crankcase 21. An intake passage 23 is connected to an upper rear portion of the cylinder 22. Although not shown, the cylinder 22 is provided with an ignition plug whose tip is exposed to the combustion chamber. The intake passage 23 is provided with an injector that injects fuel into the intake port. The injector may be provided in the cylinder 22 or in the throttle body 23a.
[0025] A throttle body 23a that controls the amount of air taken into the engine E is provided in the middle of the intake passage 23. The throttle body 23a has a throttle valve built in. The throttle body 23a is disposed between an air cleaner (not shown) and the engine E.
[0026] The pressure detection unit 24 is an intake negative pressure sensor provided in the throttle body 23a. For example, the pressure detection unit 24 is built into the throttle body 23a. For example, the pressure detection unit 24 detects the intake air pressure downstream of the throttle valve in the intake passage 23. The throttle body 23a may also have built-in an intake air temperature sensor (Ta sensor) that measures the temperature of the intake air and a throttle position sensor (TPS) that detects the throttle opening (neither of which are shown).
[0027] The fuel tank 25 includes a tank body 30 for storing fuel, a cap 31 for closing a fuel filler port of the tank body 30, and a gas-liquid separation section 32 for recovering evaporated fuel in the fuel tank 25. The gas-liquid separation section 32 is provided on the upper part of the tank body 30.
[0028] For example, an adsorbent such as activated carbon is stored in the canister 26. The canister 26 adsorbs (charges) the evaporated fuel generated in the fuel tank 25. The canister 26 introduces (purges) the adsorbed evaporated fuel into the intake system of the engine E.
[0029] The canister 26 includes a canister body 40 that stores evaporated fuel from the fuel tank 25, a charge joint 42 to which a charge hose 41 is connected, a purge joint 44 to which a purge hose 43 is connected, an air intake joint 46 to which an air intake hose 45 is connected, and a drain joint 48 to which a drain hose 47 is connected. Note that the drain hose 47 does not necessarily have to be provided.
[0030] The canister body 40 is formed in a cylindrical shape. The charge joint 42 and the purge joint 44 are provided on one end surface of the canister body 40. The air introduction joint 46 and the drain joint 48 are provided on the other end surface of the canister body 40.
[0031] The charge hose 41 is a pipe for guiding evaporated fuel generated in the fuel tank 25 to the canister 26. One end of the charge hose 41 is connected to the gas-liquid separation section 32 of the fuel tank 25. The other end of the charge hose 41 is connected to a charge joint section 42. This allows the evaporated fuel in the fuel tank 25 to be guided to the canister 26.
[0032] The purge hose 43 is a pipe for guiding the evaporated fuel adsorbed in the canister 26 to intake system components (the intake passage 23 in this embodiment) of the engine E. One end of the purge hose 43 is connected to a purge joint 44. The other end of the purge hose 43 is connected to a midway portion of the intake passage 23.
[0033] The air intake hose 45 is a pipe that can introduce air into the inside of the canister 26. One end of the air intake hose 45 is connected to an air intake joint portion 46. The other end of the air intake hose 45 opens at a position in the vehicle body where air can be introduced.
[0034] The drain hose 47 is a pipe for discharging water and the like that has entered the inside of the canister 26 to the outside of the canister 26. A first end of the drain hose 47 is connected to a drain joint portion 48. A second end of the drain hose 47 opens at a position in the vehicle body from which the water and the like can be discharged.
[0035] The PCSV 27 is disposed in the middle of the purge hose 43 near the canister 26. The PCSV 27 is an electromagnetic on-off valve. The purge hose 43 and the PCSV 27 are collectively referred to as a purge passage 43A. The PCSV 27 is controlled by the electronic control device 28 to open and close the flow path of the purge passage 43A at appropriate timing.
[0036] <Storage box> 1 to 4, the storage box 16 is shaped like a container and has an upper opening 16a that can be closed by the bottom plate of the seat 14. A box upper end 16b that forms the upper opening 16a is inclined downward toward the front in a side view. A bottom 16c of the storage box 16 is curved in a side view so as to fit along a curved region that extends from the rear of the main frame 7 to the first rear frame 9a.
[0037] The storage box 16 is divided into left and right case halves, which are joined together at the center in the width direction of the vehicle by means of bolting, adhesive, welding, etc., to form a container shape with a bottom that opens upward. The left and right case halves are each a resin molded product that is integrally formed by splitting the mold along the left-right direction. The left and right outer portions 18L, 18R closing the left and right outer sides of the storage box 16 are formed with outer bulging portions 19L, 19R that bulge outward in the vehicle width direction beyond the side edges of the upper end opening 16a, thereby increasing the box capacity.
[0038] The left and right outer parts 18L, 18R have upper outer parts 18a extending generally vertically downward from the outer edge of the upper end opening 16a. The outer bulging parts 19L, 19R are formed below the upper outer parts 18a. The outer bulging parts 19L, 19R have a bulging upper surface part 19a extending from the lower end edge of the upper outer parts 18a in a bent direction outward in the vehicle width direction, and a bulging side part 19b extending from the outer edge of the bulging upper surface part 19a in a bent direction downward. The bulging side part 19b is generally flat in the vertical direction and forms the outermost side surface 19b1 of the storage box 16. The bulging side part 19b faces the inner side surface of the vehicle body cover 11 with a specified gap. A recess is formed downward at the upper part of the outer bulging parts 19L, 19R, and a clip part 19c for fixing the vehicle body cover 11 is provided in the recess. The left outer portion 18L of the storage box 16 serves as a purge component mounting portion 18b for mounting a purge hose 43 and a purge control valve (PCSV 27).
[0039] <Canister placement> As shown in Figs. 1 and 2, the canister 26 is disposed on the inner side of the left rear frame 9 in the vehicle width direction. The canister 26 is located below the front part of the fuel tank 25 in a side view. The canister 26 is disposed, for example, along the inner side of the left first rear frame 9a in the vehicle width direction. The canister 26 is disposed with the axial direction of the cylindrical shape tilted backward with respect to the vertical direction so as to follow the inclination of the left first rear frame 9a in a side view. The canister 26 is supported on the inner side of the left first rear frame 9a in the vehicle width direction. The arrangement of the canister 26 is not limited to the above-mentioned one, and may be disposed, for example, with the axial direction along the front-rear direction, the up-down direction, or the left-right direction, or may be disposed with the axial direction tilted in various directions.
[0040] The charge hose 41 and the purge hose 43 extend in an appropriate curve from the axial upper end of the canister 26. After extending in an appropriate curve, the charge hose 41 is connected to the fuel tank 25. After extending in an appropriate curve, the purge hose 43 extends forward and downward along the left side of the storage box 16 and is connected to the intake passage 23 of the engine E. The charge hose 41 and the purge hose 43 are made of, for example, an oil-resistant and flexible rubber hose.
[0041] <Purge parts mounting structure> As shown in Figures 2 and 3, the bulging side portion 19b of the left outer portion 18L is formed with a mounting recess 51 for accommodating and attaching the PCSV27, and a mounting groove portion 55 for accommodating and attaching the purge hose 43 forward of the mounting recess 51 on the vehicle.
[0042] 6, the mounting recess 51 is formed at the upper rear end of the bulging side surface 19b. The mounting recess 51 forms a displaced outer side surface 51a displaced inward in the vehicle width direction relative to the outer side surface of the bulging side surface 19b. A fastening boss 51b protruding outward in the vehicle width direction is integrally formed with the displaced outer side surface 51a. The fastening bosses 51b are provided in a pair at the front and rear, and the front and rear fastening flanges 27a of the PCSV 27 can be fastened to the pair of fastening bosses 51b by fastening screws 51c inserted from the vehicle width direction. This fastening fixes the PCSV 27 in the mounting recess 51. In this state, the PCSV 27 is accommodated inside the outermost side surface 19b1 of the storage box 16 in the vehicle width direction, does not protrude outward in the vehicle width direction, and does not narrow the gap between the vehicle body cover 11. The fastening boss 51b is integrally formed with the mounting recess 51, and the PCSV 27 can be attached without using a separate dedicated stay or the like.
[0043] 5, a mounting groove 55 extends downward and forward from the front lower end of the mounting recess 51. The mounting groove 55 extends along the outermost side surface 19b1 of the storage box 16 with a constant semicircular cross section. The mounting recess 51 is formed in a region above the mounting groove 55 in the outer bulging portion 19L. The mounting groove 55 is formed with a retaining claw 56 that prevents the purge hose 43 housed in the groove from being removed out of the groove (outside in the vehicle width direction). The retaining claw 56 is formed in an open portion 55a on the outer side in the vehicle width direction of the mounting groove 55 so as to protrude from at least one (both in this embodiment) of both end edges 55b in the groove width direction to the inside of the open portion 55a.
[0044] 4, an opening 57 is formed in the mounting groove 55 at a portion where the retaining claw 56 is formed, which opens the bottom of the groove toward the inside of the box (inside in the vehicle width direction). When molding the left box half, this opening 57 allows a mold piece to be inserted from the inside of the box into the groove, and the retaining claw 56 that overhangs on the open portion 55a side of the mounting groove 55 can be molded. Since this opening 57 opens at the bottom of the groove, the upper part of the mounting groove 55 acts as a eaves, and the amount of water that reaches the opening 57 is small. In addition, when the purge hose 43 is inserted and held in the mounting groove 55, the opening 57 is mostly blocked by the purge hose 43. This prevents raindrops flowing on the outside of the storage box 16 from entering the storage box 16 through the opening 57.
[0045] 2, mounting groove 55 is generally inclined downward toward the front of the vehicle. A smooth crank-shaped transition portion 58 is formed in the middle of mounting groove 55 in the front-rear direction, which displaces the front portion downward relative to the rear portion.
[0046] 4, an equipment storage section 59 for storing equipment T1 such as on-board tools, documents, a puncture repair kit, etc. is provided on the inside in the vehicle width direction of the area located above the front part of the mounting groove section 55 in the outer bulge section 19L. The equipment storage section 59 stores the equipment T1 from inside the box and can hold the equipment T1 with a holding member H1 such as an endless rubber string. A plurality of hooks 61a, 61b, 61c for engaging the holding member H1 are formed on the inside in the vehicle width direction of the equipment storage section 59.
[0047] In the embodiment, a pair of lower hook portions 61a, 61b spaced apart in the front-rear direction are formed at a portion overlapping the front portion of the mounting groove portion 55 as viewed from the vehicle width direction. A single upper hook portion 61c is formed at a portion spaced upward from the center position in the front-rear direction between the front and rear lower hook portions 61a, 61b. These hook portions 61a, 61b, 61c are arranged to be located at the apexes of a triangle as viewed from the vehicle width direction. By looping the annular holding member H1 around these hook portions 61a, 61b, 61c with a predetermined tension, the accessory T1 is held in an area surrounded by the multiple hook portions 61a, 61b, 61c so as not to fall off.
[0048] Hereinafter, in the left outer portion 18L of the storage box 16, a portion facing the outer side in the vehicle width direction will be referred to as the front side, and a portion facing the inner side in the vehicle width direction (inside the box) will be referred to as the back side. 3 to 5, a bead portion 62 that bulges inwardly from the box is formed on the rear side of the left outer portion 18L by forming an attachment groove portion 55 on the front side. A pair of front and rear lower protrusions 63a, 63b that protrude inwardly from the box are formed in at least a portion of the bead portion 62 in the groove length direction.
[0049] Each of the lower protrusions 63a, 63b has a hollow shape in which a communication space 63d that communicates between the inside and outside of the box is formed. Each of the lower protrusions 63a, 63b is disposed at a position overlapping with the front and rear lower hook portions 61a, 61b in a side view. The lower hook portions 61a, 61b are formed at the tip of each of the lower protrusions 63a, 63b so as to face tip openings 63e of the communication space 63d from the inside of the box.
[0050] An upper protrusion 63c is formed on the rear side of the left outer portion 18L of the storage box 16 at a position overlapping with the upper hook portion 61c in a side view of the vehicle, protruding inward in the vehicle width direction. Like the lower protrusions 63a and 63b, the upper protrusion 63c also has a hollow shape in which a communication space 63d that communicates between the inside and outside of the box is formed. The upper hook portion 61c is formed at the tip of the upper protrusion 63c so as to face a tip opening 63e of the communication space 63d from the inside of the box.
[0051] Each of the protrusions 63a, 63b, and 63c is formed to protrude inward in the vehicle width direction from the inner surface of the left outer portion 18L of the storage box 16 facing the inside of the box. The protrusions 63a, 63b, and 63c have different protruding heights in the vehicle width direction depending on the inclination or curvature of the left outer portion 18L. Each of the protrusions 63a, 63b, and 63c is hollow and protrudes inward in the vehicle width direction. By making each of the protrusions 63a, 63b, and 63c hollow, the rigidity of each of the protrusions 63a, 63b, and 63c is ensured while reducing its weight.
[0052] 5, a tip opening 63e that opens the communication space 63d to the inside in the vehicle width direction is formed at the tip of each of the protrusions 63a, 63b, 63c on the vehicle width direction inner side. The corresponding hook portions 61a, 61b, 61c are formed so as to overlap with the tip opening 63e when viewed from the vehicle width direction. Note that in FIG. 5, the communication space 63d, the tip opening 63e, and the base end opening 63f are shown using the protrusion 63a as an example.
[0053] 4 and 5, lower hook portions 61a and 61b are formed to extend inward in the vehicle width direction from an upper edge of tip opening 63e and then bend downward. Upper hook portion 61c is formed to extend inward in the vehicle width direction from a lower edge of tip opening 63e and then bend upward.
[0054] When the holding member H1 is hooked on each of the hook portions 61a, 61b, and 61c, the tip opening 63e on the inner side in the vehicle width direction is mostly blocked by the holding member H1, so that raindrops or the like flowing on the outside of the storage box 16 are prevented from entering the storage box 16 through the tip openings 63e of the protruding portions 63a, 63b, and 63c.
[0055] 2 and 3, the base end opening 63f, which opens the communication space 63d of each lower protrusion 63a, 63b outward in the vehicle width direction, opens to the bottom of the mounting groove 55. Since the base end opening 63f opens into the groove, the upper part of the mounting groove 55 serves as a visor, and the amount of water that reaches the base end opening 63f is small. In addition, when the purge hose 43 is inserted and held in the mounting groove 55, the base end opening 63f is mostly blocked by the purge hose 43. This prevents raindrops flowing on the outside of the storage box 16 from entering the storage box 16 through the base end opening 63f.
[0056] A base end opening 63f that opens the communication space 63d of the upper protrusion 63c outward in the vehicle width direction opens to the upper part of the outer bulging part 19L. A canopy 64 is formed on the upper part of the base end opening 63f to prevent rainwater and the like from reaching the base end opening 63f. This prevents raindrops and the like flowing on the outside of the storage box 16 from entering the storage box 16 through the base end opening 63f.
[0057] As described above, the motorcycle 1 in the above embodiment includes the seat 14 on which a rider sits, the storage box 16 arranged below the seat 14, the intake passage 23 arranged forward of the storage box 16 in the vehicle longitudinal direction and connected to the engine E mounted on the vehicle, the fuel tank 25 arranged behind the storage box 16 and storing fuel to be supplied to the engine E, the canister 26 arranged so as to overlap at least a portion of the fuel tank 25 in the vehicle longitudinal direction and for adsorbing fuel evaporated in the fuel tank 25, and the intake passage 23 connected from the canister 26 to the intake passage 23. The storage box 16 is provided with a purge passage 43A extending toward the rear and having a purge control valve (PCSV27) that opens and closes the flow path, and one of the left and right outer portions 18L, 18R of the storage box 16 (the left outer portion 18L) is provided with a purge component mounting portion 18b for mounting the purge hose 43 of the purge passage 43A and the PCSV27, and the purge component mounting portion 18b is provided with a mounting recess 51 located at the upper rear side to enable the PCSV27 to be mounted, and a mounting groove portion 55 extending forward and downward from the mounting recess 51 to enable the purge hose 43 to be mounted.
[0058] According to this configuration, the purge passage 43A extends from the canister 26 disposed toward the rear of the storage box 16 toward the intake passage 23 forward of the storage box 16, and one of the left and right outer parts 18L, 18R of the storage box 16 serves as a purge component mounting part 18b for mounting the purge hose 43 and the PCSV 27 of the purge passage 43A. The purge component mounting part 18b is provided with a mounting recess 51 that enables the PCSV 27 to be mounted at a high position on the upper rear side, and a mounting groove part 55 that extends forward and downward from the mounting recess 51 and enables the purge hose 43 to be mounted. This makes it possible to prevent the periphery of the PCSV 27 and the purge hose 43 from protruding outward in the vehicle width direction while mounting the PCSV 27 and the purge hose 43 to the left outer part 18L of the storage box 16. Since the PCSV27 and the purge hose 43 are attached using the mounting recess 51 and mounting groove 55 formed in the storage box 16, a dedicated stay or the like is not required, the number of parts is reduced, mounting is made easier, and costs can be reduced. By attaching the PCSV27 at a high position on the upper rear side of the purge part mounting portion 18b and extending the purge hose 43 from the PCSV27 toward the front and downward, the purge line is less likely to become a valley piping.
[0059] In the above-mentioned motorcycle 1, at least a portion of the groove length direction of the mounting groove portion 55 is provided with a retaining claw 56 that protrudes inwardly of an opening portion 55a on the outer side of the mounting groove portion 55 in the vehicle width direction and prevents the purge hose 43 housed in the groove from coming off outward in the vehicle width direction. According to this configuration, by partially providing a retaining claw 56 on the open side of the mounting groove portion 55 to restrict the purge hose 43 housed in the mounting groove portion 55 from coming loose, the purge hose 43 can be easily and stably attached and the purge hose 43 can be prevented from protruding outward in the vehicle width direction.
[0060] In the motorcycle 1, the mounting recess 51 is integrally formed with a valve support portion (fastening boss 51b) that supports the PCSV 27. According to this configuration, the PCSV27 is attached using the valve support portion formed in the mounting recess 51, eliminating the need for a separate stay or the like, reducing the number of parts and making mounting easier, thereby reducing costs.
[0061] In the above motorcycle 1, the storage box 16 forms an upper end opening 16a that opens toward the top of the vehicle, and the left and right outer portions 18L, 18R of the storage box 16 are provided with outer bulging portions 19L, 19R that bulge outward in the vehicle width direction beyond the side edges of the upper end opening 16a, and the purge component mounting portion 18b has a mounting recess 51 formed on the upper rear side of the outer bulging portion 19L and a mounting groove portion 55 formed along the outer surface 19b1 of the outer bulging portion 19L. According to this configuration, by forming the mounting recess 51 and the mounting groove 55 using the outer bulging portions 19L, 19R that bulge outward in the vehicle width direction at the left and right outer portions 18L, 18R of the storage box 16, the PCSV 27 and the purge hose 43 can be attached to the outer portion of the storage box 16 while minimizing the impact on the box capacity.
[0062] In the above-mentioned motorcycle 1, a bead portion 62 that protrudes inwardly from the box is formed on the back side of the purge component mounting portion 18b facing the inside of the box by forming a mounting groove portion 55 on the front side, and at least a portion of the length (groove length direction) of the bead portion 62 is provided with lower protrusions 63a, 63b that protrude inwardly from the box, and the tips of the lower protrusions 63a, 63b are provided with hook portions 61a, 61b that engage a holding member H1 that holds an article inside the box. According to this configuration, the hook portions 61a, 61b that engage the item holding member H1 inside the box are formed at the tips of the protrusions 63a, 63b that protrude further inwardly from the bead portion 62, thereby utilizing the bead portion 62 on the back side of the mounting groove portion 55 to increase the height of the protrusions 63a, 63b, making it easier to engage the item holding member H1 and also reducing the height of the protrusions 63a, 63b alone, thereby reducing the amount of deformation.
[0063] In the above-mentioned motorcycle 1, the protrusions 63a, 63b have a hollow shape in which a communicating space 63d is formed to connect the inside and outside of the box, and hook portions 61a, 61b are formed so as to face the tip openings 63e of the protrusions 63a, 63b from the inside of the box. According to this configuration, the protrusions 63a, 63b are hollow to reduce weight, and the hooks 61a, 61b are formed to face the tip openings 63e of the protrusions 63a, 63b from inside the box, so that the hooks 61a, 61b overhanging the communication space 63d as viewed from the protruding direction of the protrusions 63a, 63b can be molded by splitting along the protruding direction. This makes it easier to manufacture the storage box 16.
[0064] In the motorcycle 1, the base end openings 63f of the protruding portions 63a, 63b are formed within the mounting groove portion 55. According to this configuration, by forming the base end openings 63f of the protrusions 63a, 63b within the mounting groove 55, the upper part of the mounting groove 55 acts as a eave, and it is possible to prevent water flowing outside the storage box 16 from entering the protrusions 63a, 63b without providing a separate eave shape or the like.
[0065] In the motorcycle 1, the mounting groove 55 extends at an incline so as to be positioned downward toward the front of the vehicle. According to this configuration, the mounting groove portion 55 extends at a downward incline toward the front, and the purge hose 43 held within the mounting groove portion 55 is also arranged with the front downward. This makes it difficult for a valley shape to form in the purge passage 43A, and allows the liquid flowing out from the canister 26 side to flow into the intake passage 23 without being trapped.
[0066] The present invention is not limited to the above embodiment. For example, in the embodiment, the storage box 16 is shown as an example of a box body, and the configuration in which the purge hose 43 and the PCSV27 are attached to the outer part of the storage box 16 is illustrated, but the present invention is not limited to this configuration. For example, the box body to which the purge parts are attached is not limited to the storage box 16, but may be other box bodies such as an air arena box or a battery box. In the case of the storage box 16, it is not limited to the one having the outer bulging parts 19L, 19R that bulge outward in the vehicle width direction from the side edges of the upper end opening 16a, but may be a configuration in which the upper end opening 16a itself is widened. It is not limited to the configuration in which the purge parts are attached to the left side of the box body, but the purge parts may be attached to the right side of the box body or any other arbitrary part. The configuration of this embodiment may be applied to saddle-ride type vehicles other than motorcycles. The saddle-ride type vehicles include all vehicles on which a driver straddles the vehicle body, including not only motorcycles (including motorized bicycles and scooter-type vehicles), but also three-wheeled vehicles (including vehicles with one front wheel and two rear wheels, as well as vehicles with two front wheels and one rear wheel) or four-wheeled vehicles (such as four-wheeled buggies). The configuration may be applied to vehicles that include an electric motor as a prime mover. The configurations in the above-described embodiments are merely examples of the present invention, and various modifications are possible without departing from the gist of the present invention, such as replacing the components of the embodiments with well-known components.
