    • A lawn tractor has an engine, front wheels and rear wheels, a body frame extending longitudinally of the tractor, a mower unit supported by the body frame, a grass catcher supported by the body frame, a blower unit supported by the body frame, and a duct for transporting grass clippings cut by the mower unit into the grass catcher. The duct includes a first duct portion extending between the mower unit and the blower unit, and a second duct portion extending between the blower unit and the grass catcher. An output shaft of the engine, an input shaft of the mower unit and an input shaft of the blower unit all extend vertically. The engine output shaft, mower input shaft and blower input shaft are arranged inwardly of the rear wheels in the transverse direction of the body frame and substantially linearly in the longitudinal direction thereof. The engine output shaft and mower input shaft are interconnected through a first belt transmission mechanism, and the mower input shaft and blower input shaft are interconnected through a second belt transmission mechanism.
    • 草坪拖拉机具有发动机,前轮和后轮,拖拉机纵向延伸的车体框架,由车身框架支撑的割草机单元,由车体框架支撑的割草机,由车身框架支撑的鼓风机单元,以及 用于将由割草机单元切割的草屑运送到捕草器中的管道。 所述管道包括在所述割草机单元和所述鼓风机单元之间延伸的第一管道部分和在所述鼓风机单元和所述捕草器之间延伸的第二管道部分。 发动机的输出轴,割草机单元的输入轴和鼓风机单元的输入轴全部垂直延伸。 发动机输出轴,割草机输入轴和鼓风机输入轴在主体框架的横向方向上布置在后轮的内侧,并且在其纵向方向上基本上线性地布置。 发动机输出轴和割草机输入轴通过第一带传动机构相互连接,割草机输入轴和鼓风机输入轴通过第二传动机构相互连接。

    • A rodless cylinder which is capable of minimizing the leak of pressure fluid from a cylinder tube. A slit of an almost trapezoidal section is formed in the cylinder tube in a longitudinal direction thereof, a trapezoidal belt which is fixed to the ends of the cylinder tube at the both ends thereof is fitted into the slit, the trapezoidal belt slidably passes through a piston which is fitted into the cylinder tube, and a piston cup is fitted on the outer periphery of the piston. In addition, ribs are provided between an outer lip of the piston cup which is in abutment against the vicinity of the both sides of the bottom of the trapezoidal belt and an inner lip of the piston cup, and the both side walls of tile slit of the almost trapezoidal section are formed into convexly curved configurations in such a manner that the both side walls of the slit can be connected to the inner peripheral surface of the cylinder tube forming a smooth curve. And, on the both upper side walls of the slit, there are provided projection strips for nipping and holding the trapezoidal belt therebetween.
    • 无杆气缸,其能够最小化来自气缸管的压力流体的泄漏。 在缸筒的长度方向上形成有大致梯形截面的狭缝,在其两端固定有气缸筒的端部的梯形带嵌合在狭缝中,梯形带可滑动地穿过 活塞装配到缸筒中,活塞杯安装在活塞的外周上。 此外,在活塞杯的外唇之间设置有肋,该外唇与梯形带的底部的两侧附近和活塞杯的内唇相邻,并且瓦片的两个侧壁 几乎梯形部分形成为凸形弯曲构造,使得狭缝的两个侧壁可以连接到气缸管的内周表面,形成平滑的曲线。 并且,在狭缝的两个上侧壁上设置有用于将梯形带夹持并保持在其间的突起条。
