Steel frame sub-frames 11 are connected to the frame front portions 10a and 10a, and pipe-shaped cross members 12 are connected to the rear ends of the frame intermediate portions 10b and 10b. Further, a square floor panel 13 is welded to the upper portions of the frame intermediate portions 10b and 10b. Seat rails 16 are connected to the upper ends of the frame rear portions 10c and 10c to connect them together. In addition, the lower end portions of the pair of left and right support columns 17 and 17 that are inclined to the rear are welded to the front end portions of the frame front portions 10a and 10a. The vehicle body frame 1 is configured as described above.

  A driver's seat 6 is attached to the seat rail 16. An auxiliary equipment storage box 18 for storing auxiliary equipment such as a battery 19 is attached between the rear portions 10c and 10c of the frame from the front side.

  As shown in FIGS. 2, 3 and 6, left and right front wheels 2 f and 2 f are suspended independently from the sub-frame 11 via front suspension devices 20 and 20, respectively. Each of the front suspension devices 20 includes an A-type front suspension arm 21 and an extendable front damper 22 that have an inner end branched in a forked shape. The front suspension arm 21 has a pair of front and rear bosses 21 a and 21 a at its inner end supported by a pair of front and rear pivots 23 and 23 fixed to the subframe 11 and extending in the front-rear direction via elastic bushes 24 and 24. The vertical suspension of the front suspension arm 21 is buffered between each front suspension arm 21 and the column 17 on the same side. The front damper 22 is connected.

  A knuckle 26 having an axle 25 that rotatably supports the front wheel 2 f on the same side is connected to an outer end of the front suspension arm 21, that is, a swinging end via a king pin 27 so as to be capable of turning.

  On the other hand, the handle column 28 supported by the subframe 11 and the left and right support columns 17, 17 is disposed in the center between the support columns 17, 17, and the steering handle is disposed above the handle column 28. 3 is interlocked and connected to the left and right knuckles 26, 26 via the steering mechanism 4.

  The steering mechanism 4 is rotatably supported by the steering handle 3 and has a steering shaft 29 whose upper end is coupled to the steering handle 3 and an integrally formed lower end of the steering shaft 29. And a pair of left and right tie rods 31 and 31 connecting the steering arm 30 to the knuckle arms 26a and 26a of the left and right knuckles 26 and 26, respectively. The knuckle arm 26a extends rearward from the king pin 27 from the lower end portion of the knuckle 26. The knuckle arm 26a rotates around the king pin 27 according to the steering of the steering handle 3, and can turn the left and right front wheels 2f, 2f. .

  As shown in FIGS. 1 to 2, 6 and 7, a movable fender 35 is disposed above each front wheel 2 f so as to cover a substantially semicircular surface of the upper portion of the front wheel 2 f. It attaches to the corresponding knuckle 26 so that it can turn together with the front wheel 2f. That is, the movable fender 35 is made of synthetic resin, and has an arcuate peripheral wall portion 35a that covers the upper portion of the outer peripheral surface of the front wheel 2f, an inner wall portion 35b that covers the upper inner surface portion of the front wheel 2f, and an upper peripheral edge of the outer surface of the front wheel 2f. The inner wall portion 35b is formed with a first vertical mounting portion 36 at the center thereof and a second horizontal mounting portion at the rear end thereof. A portion 37 is formed. On the other hand, the knuckle 26 is formed with a pair of front and rear brackets 38, 38 standing at the upper end thereof, and a first attachment portion 36 is fastened to the brackets 38, 38 by bolts 39, 39, and a second knuckle arm 26a is connected to the second knuckle arm 26a. The attachment portion 37 is fastened by the bolt 40. If the bolts 39 and 40 are removed, the movable fender 35 can be removed from the knuckle 26.

  The left and right movable fenders 35 and 35 are arranged so that at least the front end portion thereof is within the field of view A of the driver D sitting on the seat 6 (see FIG. 2).

  Thus, during the operation of the small vehicle V, the driver D observes the movable fenders 35 and 35 that turn together with the left and right front wheels 2f and 2f, thereby accurately determining the position and orientation of the front wheels 2f and 2f on the road. Therefore, it can be easily operated on rough roads and narrow corners.

  Moreover, since the movable fenders 35 and 35 need only be relatively small in area so as to cover directly above the front wheels 2f and 2f, the front wheels to be turned over a wide range like a fixed front fender integrated with the body of a conventional small vehicle. Compared to the one formed to cover with, it can contribute to the reduction of the vehicle body width, and does not give a sense of intimidation to pedestrians while running on the sidewalk.

  Each movable fender 35 can be easily attached by bolting the first and second attachment portions 37 of the inner wall portion 35b to the brackets 38 and 38 of the knuckle 26 and the knuckle arm 26a that pivotally support the front wheel 2f. In addition to this, simultaneous turning of the movable fenders 35, 35 with the front wheels 2f, 2f can be ensured.

  Furthermore, since each movable fender 35 can be attached to and detached from the knuckle 26 alone, at the time of damage, only the movable fender 35 can be replaced with a new part regardless of other members, thereby reducing the maintenance cost. be able to.

  As shown in FIGS. 6 to 11, in each movable fender 35, a mud scraping means 43 for scraping mud adhering to the front wheel 2 f is provided at the rear end portion of the peripheral wall portion 35 a. The mud scraping means 43 extends over the entire width of the lower end of the movable fender 35, and thus has a first soil removal piece 44 formed longer than the lateral width of the front wheel 2f, and the circumferential wall portion 35a directly above the first soil removal piece 44. The second soil removal piece 45 is formed at the lower edge of the slit 46 that opens over the entire width, and the second soil removal piece 45 is also formed longer than the lateral width of the front wheel 2f. The first earth discharging piece 44 has its tip inclined downward with respect to the outer peripheral surface of the front wheel 2f, and scrapes off mud adhering to the outer peripheral surface when the front wheel 2f rotates forward. The tip of the soil discharge piece 45 is inclined upward with respect to the outer peripheral surface of the front wheel 2f, and when the front wheel 2f is rotated backward, the mud adhering to the outer peripheral surface is scraped off and discharged out of the slit 46. Yes. In particular, the first earth discharging piece 44 has its tip protruding obliquely downward with respect to the outer peripheral surface of the front wheel 2f, and the second earth discharging piece 45 has its tip protruding obliquely upward with respect to the outer peripheral surface of the front wheel 2f. Therefore, when the front wheel 2f is at the front end and at the time of reverse rotation, the first and second earthing pieces 44 and 45 tend to bite into the mud on the outer peripheral surface of the front wheel 2f, and the mud can be scooped up smoothly. , Contributes to the improvement of the muddying effect.

  The slit 46 is provided with a thin reinforcing wall 47 in the left-right direction that connects the upper and lower edges at the center of the left and right. The reinforcing wall 47 serves to reinforce the periphery of the slit 46 and the first and second earth discharging pieces 44 and 45. Further, the reinforcing wall 47 is disposed so as to be closer to the outer peripheral surface of the front wheel 2f than the two soil discharge pieces 44, 45, and when the rear end portion of the movable fender 35 is elastically deformed so as to be close to the front wheel 2f, the reinforcing wall 47 Is in contact with the outer peripheral surface of the front wheel 2f to prevent the two earthing pieces 44, 45 from contacting the front wheel 2f. Accordingly, when the front wheel 2f is mud scraped by the first soil discharge piece 44 or the second soil discharge piece 45, the reinforcing wall 47 is not the outer periphery of the front wheel 2f even if the first soil discharge piece 44 or the second soil discharge piece 45 bites into the mud. By abutting on the surface, excessive biting of each of the soil discharge pieces 44 and 45 can be prevented.

  As shown in FIGS. 6, 8, and 10, a third earth discharging piece 48 that is close to the outer surface of the front wheel 2 f is formed at the rear end portion of the outer wall portion 35 c of each movable fender 35. The lower end of the third earth discharging piece 48 is connected to the tip of the first earth discharging piece 44, and the mud adhering to the outer surface is scraped off when the front wheel 2f is rotated forward.

  As shown in FIGS. 7, 10 and 11, the inner surface of the inner wall 35b of the movable fender 35 has an inner surface of the front wheel 2f which is inclined forward and is lowered toward the lower edge of the inner wall 35b. A soil discharge piece 49 projecting toward the surface is integrally formed, and the soil discharge piece 49 scrapes back the mud adhering to the side surface particularly when the front wheel 2f rotates forward.

  Thus, by scraping off the mud adhering to the front wheels 2f as described above, mud clogging between each front wheel 2f and the movable fender 35 can be prevented, and smooth rotation of each front wheel 2f can be ensured. Therefore, smooth running is possible even in a mud place, and in addition, the driver D can grasp the mud state on the road surface by visually checking the scraped state of mud from the front wheels 2f and 2f during driving.

  Here, the attachment structure of the movable fender 35 to the knuckle 26 will be described in more detail. A pair of front and rear first pairs disposed so as to sandwich a vertical plane P (see FIG. 9) including the rotation axis of the front wheel 2f is attached to the vertical first mounting portion 36 formed on the inner wall portion 35b of the movable fender 35. Attachment holes 36a and 36a are provided, and a second attachment hole 37a is provided in the horizontal second attachment part 37 formed at the lower end of the inner wall part 35b in the vicinity of the mud means 43. The first and second attachment holes 36a and 37a are long holes extending in the front-rear direction. The first attachment portion 36 is fixed to the pair of front and rear brackets 38, 38 on the upper portion of the knuckle 26 by bolts 39, 39 inserted through the first attachment holes 36a, 36a. The first attachment portion 36 is fixed to the rear end portion of the knuckle arm 26a with a bolt 40 inserted through the second attachment hole 37a. When they are fixed, the movable fender 35 is moved back and forth along the major axis direction of the first and second mounting holes 36a and 37a, in particular, the reinforcing wall 47, the first soil removal piece 44 and the second soil removal. The gap between the piece 45 and the front wheel 2f is adjusted to an appropriate gap effective for muddying.

  Thus, since the movable fender 35 is supported by the knuckle 26 by the second attachment portion 37 close to the mud scraping means 43 as described above, when the front wheel 2 f is mud by the mud scraping means 43, It is possible to prevent the deformation of the movable fender 35 as much as possible by directly transmitting and supporting the applied load to the knuckle 26.

  Further, since the first attachment portion 36 of the movable fender 35 is supported by the knuckle 26 at two places before and after being arranged so as to sandwich the vertical plane P including the rotation axis of the front wheel 2f, it is compatible with the support of the second attachment portion 37. As a result, the entire movable fender 35 can be firmly supported by the knuckle 26. Moreover, since the first and second attachment portions 36a and 37a are perpendicular to each other, the support rigidity of the movable fender 35 is high, and the attachment posture of the movable fender 35 can be contributed to stabilization and vibration prevention.

  In FIGS. 1 and 4 to 6, a pair of left and right guard members 32 projecting to the upper side of the front wheels 2 f and 2 f on the same side while surrounding the front damper 22 on the same side on the left and right sides of the front portion of the body frame 1. 32 is disposed. Each guard member 32 is formed by bending a pipe material into a loop shape, and includes a linear grip portion 32g extending in the front-rear direction, and a pair of front and rear leg portions 32a extending downward from both ends of the grip portion 32g. 32b and the rear leg 32b on the outer surface of the front frame 10a of the main frame 10, and the front leg 32a on the outer surface of the column 17 on the same side. By being fixed by, for example, the body frame 1 is supported. The leg portions 32a and 32b are disposed so as to be inclined upward at the outer end so as to pass through the front and rear sides of the front damper 22 and between the front cover 91, the front side cover 90 and the leg shield 7 and the front wheel 2f. The portion 32g occupies the upper position of the front wheel 2f and the movable fender 35.

  Thus, the left and right guard members 32, 32 prevent an obstacle such as a fallen object from entering between the front cover 91 and the front wheels 2f, 2f, and the movable fender 35, the front wheel 2f and the front damper from the obstacle. 22 etc. can be protected.

  Further, since the grip portion 32g of each guard member 32 is exposed above the movable fender 35, when the assistant lifts the front portion of the small vehicle V, the grip portion 32g is obstructed by the front cover 91 or the like. Can be easily gripped without lifting, and the lifting workability is improved. Further, since the grip portion 32g is arranged above the movable fender 35, the movable fender 35 receives the scattered muddy water of the front wheel 2f, so that the dirt due to the muddy water of the grip portion 32g can be avoided. I won't get my hands dirty. Thus, the burden on the assistant when lifting the front portion of the small vehicle V is reduced.

  Furthermore, since both the leg portions 32a and 32b of the guard member 32 are fixed to the vehicle body frame 1, the support strength of the guard member 32 is high, and it can sufficiently withstand the lifting load.

  3 and 12 to 14, the power unit 5 is suspended from the rear portion of the main frame 10 via a rear suspension device 51, and a pair of left and right rear wheels 2 r and 2 r are supported by the power unit 5. The casing 52 of the power unit 5 is composed of a reduction case 52a and a pair of left and right axle cases 52b and 52b that are integrally projected on the left and right side walls at the bottom of the reduction case 52a. On the side, an electric motor 53 using the battery 19 as a power source is attached, and an output shaft 53a of the electric motor 53 is arranged so that a pinion gear 54 formed at the tip of the electric motor 53 enters the reduction case 52a.

  In the reduction case 52a, a differential case 56 of the differential 55 is disposed coaxially with the left and right axle cases 52b, 52b, and both left and right ends thereof are rotatably supported by the reduction case 52a via ball bearings 57, 57. Is done. A large-diameter final gear 58 is splined to the differential case 56. In the reduction case 52a, an intermediate transmission shaft 59 is disposed at an intermediate portion between the output shaft 53a and the axle cases 52b and 52b, and both left and right end portions thereof are rotatably supported by the reduction case 52a. A large-diameter gear 60 that meshes with the pinion gear 54 and a small-diameter gear 61 that meshes with the final gear 58 are fixed to the intermediate transmission shaft 59. Thus, the pinion gear 54, the large-diameter gear 60, the small-diameter gear 61, and the final gear 58 constitute a reduction device 62 that transmits the rotation of the output shaft 53a of the electric motor 53 to the differential case 56 with a constant reduction ratio.

  The left and right rear axles 63, 63 penetrating the left and right axle cases 52 b, 52 b are respectively supported by the inner peripheral surfaces of both ends of the differential case 56 so as to be relatively rotatable, and the rear axles 63, 63 enter the differential case 56. Side gears 64 and 64 are spline-coupled to the inner end portions. The differential case 56 is attached with a pinion shaft 65 orthogonal to the rotational axis thereof, and a pair of pinion gears 66, 66 meshing with the both side gears 64, 64 are rotatably supported by the pinion shaft 65. Thus, the differential case 56, the pinion gears 66, 66, and the side gears 64, 64 constitute a differential device 55 that distributes the rotation of the final gear 58 to the left and right rear axles 63, 63.

  The left and right rear axles 63, 63 are supported on the outer ends of the left and right axle cases 52b, 52b via ball bearings 67, 67. The left and right rear wheels 2r, 2r are integrally attached to the front ends of the left and right rear axles 63, 63 protruding from the outer ends of the left and right axle cases 52b, 52b. Therefore, the rear wheels 2r, 2r are supported by the axle cases 52b, 52b via the rear axles 63, 63.

  The rear suspension device 51 includes a pair of left and right rear suspension arms 70 and 70 and a pair of left and right extendable rear dampers 71 and 71. Each rear suspension arm 70 has a boss portion 70a at the front end thereof fixed to a bracket 69 at the rear end portion of the frame intermediate portion 10b and supported by a pivot 72 extending in the left-right direction via a front elastic bush 73. It can swing up and down around the pivot 72.

  A pair of front and rear support bases 75 and 75 are fixed to the rear end portion of each rear suspension arm 70 by welding, and a pair of front and rear support arms 76 and 76 'disposed above the support bases 75 and 75 are provided. Projecting integrally on both front and rear surfaces of the axle case 52b on the same side. These support arms 76, 76 'are provided with rear elastic bushes 77, 77 having their axes directed upward and downward as follows.

  That is, each rear elastic bush 77 has an outer cylinder 78 and an inner cylinder 79 disposed concentrically on the inner and outer peripheral surfaces thereof, and the outer cylinders 78 and 78 of the front and rear rear elastic bushes 77 and 77 are supported by support arms. Press-fitted into 76 and 76 ', respectively. The inner cylinders 79 and 79 of the front and rear elastic bushes 77 and 77 are clamped and fixed between the support bases 75 and 75 and the presser plate 83 through bolts 80 and 80 penetrating them.

  In the above, each front elastic bush 73 is formed such that the elastic modulus in the vertical direction is smaller than the elastic modulus in the front-rear direction. Each rear elastic bush 77 is formed such that the elastic modulus in the left-right direction is smaller than the elastic modulus in the front-rear direction.

  A bracket 81 standing upward is fixed to each front support arm 76, and both end portions of the rear damper 71 are connected to the bracket 81 and the upper end portion of the frame rear portion 10c.

  Thus, when the rear wheels 2r and 2r are driven by the output of the power unit 5, the reaction torque acting on the casing 52 is transmitted from the support arms 76 and 76 'of the axle case 52b to the pair of front and rear elastic bushes 77 and 77, bolts. It is transmitted to and received by the rear suspension arm 70 through 80 and 80 and the support bases 75 and 75. In the meantime, the impact of the reaction torque is moderated moderately by the elastic deformation of the front and rear rear elastic bushes 77, 77. However, the rear elastic bushes 77, 77 are arranged at the front and rear with the rear axle 63 in between. Since the resistance against the force torque can be sufficiently exerted, and the elastic modulus in the front-rear direction of the rear elastic bushing 77 is set to be relatively large, the support rigidity of the power unit 5 can be increased. Therefore, excessive swinging of the entire power unit 5 due to can be suppressed, and power transmission to the rear wheels 2r, 2r can be performed accurately.

  The pair of rear dampers 71 and 71 connected to the left and right support arms 76 and 76 on the front side of the axle cases 52b and 52b also work against the reaction torque of the power unit 5, so that the support rigidity of the power unit 5 is enhanced. Will contribute.

  When the small vehicle V is traveling, when different impact forces are applied to the left and right rear wheels 2r, 2r from the road surface, the axle cases 52b, 52b are caused to move by the elastic deformation of the front elastic bush 73 and the rear elastic bushes 77, 77. Accordingly, the left and right rear wheels 2r, and the left and right rear suspension arms 70, 70 are relatively swung up and down accordingly. Individual lifting / lowering of 2r is possible, the ground contact property of each rear wheel 2r can be improved, and it can contribute to the improvement of riding comfort. In particular, setting the elastic modulus in the left-right direction of each rear elastic bush 77 to be relatively small promotes the relative swinging of the left and right rear suspension arms 70, 70, and further improves the ground contact property of each rear wheel 2r. It is effective in planning.

  In addition, when turning, even if the rear wheels 2r and 2r receive a lateral load, the pair of front and rear and left and right rear elastic bushes 77 and 77; The lateral support rigidity of the rear wheels 2r, 2r can be increased, and the posture of the rear wheels 2r, 2r can be stabilized.

  Since such a rear suspension device 51 has a simple structure and is easy to assemble, it can be provided at low cost.

  1 and 3 to 5, a pair of left and right fourth brackets 85, 85 projecting obliquely downward are welded to the upper end of the frame rear portion 10 c, and the power bracket 5 is connected to the fourth brackets 85, 85. Both ends of the rear bumper 71 having a U shape so as to surround the electric motor 53 are fixed by bolts 87. The rear bumper 71 serves to prevent the electric motor 53 from being damaged by an obstacle behind the vehicle, and also serves as a grip for lifting the rear portion of the small vehicle V and for holding the small vehicle V on the loading platform during transportation by the vehicle. It can also be used as a locking portion of the holder.

  1 to 3 again, the left and right support columns 17, 17 cover the front side covers 90, 90 that cover the left and right sides of the support columns, the front surfaces of the support columns 17, 17, and the handle column 28, and the front side covers. The front cover 91 that connects the covers 90, 90 and the leg shield 7 that covers the rear surfaces of the columns 17, 17 and the handle column 28 and connects the front side covers 90, 90 are removed by bolts (not shown). It is fixed as possible. In this way, the leg shield 7 is arranged so as to project outward from the left and right sides of the handle column 28 and cover both legs of the driver D sitting on the seat 6 from the front. The width of the leg shield 7 is set to be shorter than the distance between the inner edges of the left and right movable fenders 35 and 35 so as to minimize the intimidation of pedestrians passing on the sidewalk, as with the floor panel 13. At the lower end of the leg shield 7, an auxiliary cover 92 that is wider than the left and right movable fenders 35 and 35 and is inclined downwardly and covers the gap between them is integrally provided. It is bolted to the floor panel 13. Both end portions 92 a and 92 a of the auxiliary cover 92 covering the rear portions of the left and right movable fenders 35 bulge outward in the radial direction of the movable fender 35 and are formed in an arc shape along the outer periphery of the movable fender 35. A floor mat 14 is laid on the upper surface of the floor panel 13 so as to cover the joint portion of the auxiliary cover 92. The floor panel 13 and the floor mat 14 constitute a footrest portion for the driver D, that is, a step floor 15.

  Thus, the auxiliary cover 92 is wider than the leg shield 7 so as to cover the rear part of the left and right movable fenders 35 and 35 and the space between the leg shield 7 and the step floor 15. The auxiliary cover 92 can catch muddy water leaking from the fenders 35 and 35 and splashing backward.

  In addition, since the auxiliary cover 92 is connected to the lower part of the leg shield 7, even if the width of the auxiliary cover 92 is wider than that of the leg shield 7, the pedestrian is not intimidated.

  Further, both end portions 92a and 92a of the auxiliary cover 92 covering the rear portions of the left and right movable fenders 35 bulge outward in the radial direction of the movable fender 35 and are formed in an arc shape along the outer periphery of the movable fender 35. A sufficient gap between the movable fenders 35 and 35 and the auxiliary cover 92 can be secured to avoid interference between the movable fenders 35 and 35 and the auxiliary cover 92 when the front wheels 2f and 2f are turned.

  Furthermore, since the auxiliary cover 92 is disposed between the leg shield 7 and the step floor 15, its lateral width is wider than that of the leg shield 7, and is inclined rearwardly downward, the auxiliary cover 92 is operated. It can also be used as an auxiliary step in which the person D can put his / her foot in a stretched state, which can contribute to an improvement in comfort.

  A pair of left and right headlights 93, 93 are attached to the lower part of the front cover 91, and front front turn signals 94, 94 are attached to the upper parts of the left and right front side covers 90, 90. A rear cover 95 that covers the power unit 5 and the left and right rear wheels 2r, 2r is fixed to the rear portion of the main frame 10, and a taillight 96 is attached to the rear surface of the rear cover 95.

  The driver's seat 6 includes a seat cushion 6a supported by the seat rail 16 and a seat back 6b that stands up from a rear end portion of the seat cushion 6a. The seat back 6b is integrally provided with support plates 97, 97 on the left and right side surfaces thereof, and a pair of left and right armrests 98, 98 are mounted on the support plates 97, 97 in a horizontal use position and a retracted position in which the seat stand 6b stands upward. It is pivotally supported so that it can rotate between the two. Reinto blinkers 95, 95 are attached to the upper portions of the support plates 97, 97 above the armrests 98, 98.

  Further, as clearly shown in FIG. 1, an L-shaped rear side cover 100 is attached to the frame middle portion 10 b and the frame rear portion 10 c of the main frame 10 to cover them. The rear side cover 100, the front side cover 90, and the support plate 97 are representative of the flat side surfaces of the body of the small vehicle V, and the reflectors 101 or the light emitters are attached to the outer surfaces over almost the entire area. The A metallic coating, a light-colored gray coating, a reflecting mirror or the like is suitable for the reflector 101. When a metallic coating, particularly a silver metallic coating, is adopted, the reflector 101 can be simply configured by painting. In addition, since the reflectivity to the irradiated light is relatively high, the visibility is good.

  In addition, a phosphorescent material or fluorescent material is appropriate for the light emitter, and when this is adopted, it emits positively when irradiated with headlights from other vehicles, so it has high visibility. .

  The reflectors 102 or light emitters similar to those described above are also attached to the outer surfaces of the front wheels 2f and 2f and the rear wheels 2r and 2r.

  Thus, at night, when the small vehicle V is crossing the roadway, when the headlight of another vehicle is irradiated to the side of the vehicle body, the rear side cover 100, the front is reflected by the reflected light of the reflectors 101 and 102 or the light emission of the light emitter. Since the side cover 90 and the support plate 97, and the front wheel 2f and the rear wheel 2r are lifted, the driver of the other vehicle can easily recognize the entire small vehicle V, and the side of the small vehicle V at night is good. Visibility can be obtained.

  The present invention is not limited to the above embodiments, and various design changes can be made without departing from the scope of the invention. For example, the small vehicle V can be configured as a tricycle with the rear wheel 2r as a single wheel.
