    • A small vehicle has an engine 40 mounted on a vehicle body 5. Power from the engine is taken out through a power output shaft 41. The power is further transmitted from a drive sprocket 42 mounted on the power output shaft 41 toward a drive wheel of the vehicle. A vicinity of a part 51a of the crankcase 51 covering a crank web 53a of the crankshaft 53 is recessed to form a space 99 in which the drive sprocket 42 is disposed.
      Accordingly, the engine may be positioned with a large degree of freedom, a drive seating area may be secured easily, appropriate positioning of the drive sprocket on the drive wheel side and the driver is not adversely affected, and the vehicle weight distribution is well balanced.
    • 小型车辆具有安装在车身5上的发动机40.来自发动机的动力通过动力输出轴41被取出。动力从安装在动力输出轴41上的驱动链轮42进一步传递到动力输出轴41的驱动轮 机动车。 覆盖曲轴53的曲轴53a的曲轴箱51的部分51a的附近被凹入,形成驱动链轮42设置在其中的空间99。 因此,发动机可以以较大的自由度定位,可以容易地固定驱动器座位区域,驱动链轮适当地定位在驱动轮侧,并且驾驶员不会受到不利影响,并且车辆重量分布良好地平衡 。

    • A small-sized vehicle is provided in which, in order to cover an upper part of a wheel (2f), a fender (35) is disposed along the outer peripheral face thereof, wherein formed on the fender (35) are a first soil removing piece (44) projecting from the rear edge of the fender (35) toward the outer peripheral face of the wheel (2f), a slit (46) positioned above the first soil removing piece (44) and extending in the width direction of the wheel (2f), and a second soil removing piece (45) projecting from the lower edge of the slit (46) toward the outer peripheral face of the wheel (2f); when the wheel (2f) rotates forward, the first soil removing piece (44) scrapes off mud on the outer peripheral face of the wheel (2f) downward, and when the wheel (2f) rotates rearward, the second soil removing piece (45) scrapes off mud on the outer peripheral face of the wheel (2f) and discharges it outside through the slit (46). In this way, when a structure is employed in which, in order to cover an upper part of a wheel, a fender is disposed along the outer peripheral face thereof, by preventing mud from clogging a gap between the wheel and the fender a small-sized vehicle can be provided that enables travel in a muddy place with little effort.
    • 提供一种小型车辆,其中为了覆盖车轮(2f)的上部,挡板(35)沿其外周面设置,其中形成在挡泥板(35)上的是第一土壤 从所述挡泥板(35)的后缘朝向所述车轮(2f)的外周面突出的拆卸片(44),位于所述第一除污片(44)的上方并在宽度方向 所述车轮(2f)和从所述狭缝(46)的下边缘朝向所述车轮(2f)的外周面突出的第二除污片(45)。 当车轮(2f)向前旋转时,第一除污片(44)向下刮擦轮(2f)的外周面上的泥浆,当车轮(2f)向后旋转时,第二除污片 )刮擦轮(2f)的外周面上的泥浆,并通过狭缝(46)将其排出外部。 以这种方式,当为了覆盖车轮的上部时,通过防止泥浆堵塞车轮和挡泥板之间的间隙,沿着其外周面设置翼子板, 可以提供能够在很少的努力下在泥泞的地方行进的大小的车辆。

    • A shock absorber (41) includes a cylinder having an internal space formed therein and a piston (43) arranged in the internal space for partitioning the internal space into a compression-side oil chamber (44) and an extension-side oil chamber (45). A first oil chamber (46) is connected to the extension-side oil chamber (45). A second oil chamber (47) is connected to a compression-side oil chamber (44). A first valve (50) only allows the hydraulic oil to flow from the first oil chamber (46) into a third oil chamber (48). A second check valve (51) only allows the hydraulic oil to flow from the second oil chamber (47) into the third oil chamber (48). A damping force generating valve (54) only allows the hydraulic oil to flow from the third oil chamber (48) into a fourth oil chamber (49). The damping force generating valve (54) generates a flowing resistance when the hydraulic oil flows from the third oil chamber (48) into the fourth oil chamber (49). A third check valve (52) only allows the hydraulic oil to flow from the fourth oil chamber (49) into the first oil chamber (46). A fourth check valve (53) only allows the hydraulic oil to flow from the fourth oil chamber (49) into the second oil chamber (47).
    • 减震器(41)包括形成有内部空间的缸体和设置在内部空间中的活塞(43),用于将内部空间分隔成压缩侧油室(44)和延伸侧油室(45) )。 第一油室(46)连接到延伸侧油室(45)。 第二油室(47)连接到压缩侧油室(44)。 第一阀(50)仅允许液压油从第一油室(46)流入第三油室(48)。 第二止回阀(51)仅允许液压油从第二油室(47)流入第三油室(48)。 阻尼力产生阀(54)仅允许液压油从第三油室(48)流入第四油室(49)。 当液压油从第三油室(48)流入第四油室(49)时,阻尼力产生阀(54)产生流动阻力。 第三止回阀(52)仅允许液压油从第四油室(49)流入第一油室(46)。 第四单向阀(53)仅允许液压油从第四油室(49)流入第二油室(47)。
