摘要： Plant cutter apparatus includes a handling rod (11), a drive source unit (13) mounted on one end portion (11a) of the handling rod (11) via a clutch case (40), and a cutter blade (14) mounted on the other end portion of the handling rod for being rotated by activation of the drive source unit. With the handling rod inserted in an axial loosely-fitting hole (43c) of the clutch case, the one end portion of the handling rod abuts at its end surface against an abutting region (43d) formed on the way through the loosely-fitting hole. The drive source unit is supported by the end surface of the handling rod via a drive-source mounting portion (43) of the clutch case. The drive source unit is allowed to freely vibrate about the one end portion of the handling rod supporting the unit, so that a flexible coupling portion (42) of the clutch case can perform a vibration attenuation function to reduce vibrations transmitted from the drive source unit to the handling rod.

摘要： A drive shaft (12) to be inserted into a pipe-shaped operating pole (11) for use in a portable working machine is provided. The drive shaft has at least one resin bush (60) integrally formed on its outer peripheral surface. Thus integrally forming the bush on the drive shaft allows agreement between the axis center of the operating pole, the axis center of the bush and the axis center of the drive shaft, preventing the change of position of the bush during the use of the working machine, and resulting in the reduction of vibration of the drive shaft with the simple configuration.

摘要： Drive shaft (12) of a plant cutter apparatus includes an elongate main shaft portion (21) made of a titanium alloy, and end shaft portions (22, 26) made of steel and integrally joined to the opposite ends of the main shaft portion (21). The titanium alloy has substantially the same mechanical strengths as the steel. Therefore, the titanium-alloy-made main shaft portion (21) can secure rigidity that is normally required of the plant cutter's drive shaft, and can also reduce the weight of the drive shaft to thereby minimize unwanted sagging-induced vibrations of the drive shaft (12) caused by the shaft's own weight.

摘要： In a plant cutter apparatus, a handling rod (11) includes an outer pipe portion (71), an inner pipe portion (72) and three radial stay portions (73, 74, 75) interconnecting the outer and inner pipe portions. The three stay portions (73, 74, 75) are arranged, about an axial centerline (P1) of the rod, at non-equal angular intervals in such a manner that angles (θ1, θ2, θ3) formed between the three stay portions differ from each other. Thus, the rod has a cross-sectional configuration asymmetric about the axial centerline. Geometric moment of inertia of the thus-constructed handling rod takes different values in all angular positions about the axial centerline, and thus the inherent vibrating frequency of the rod also takes different values in all the angular positions. Consequently, the rod's inherent vibrating frequency coincides with a frequency of vibrations transmitted from a drive source unit in only one of the angular positions, so that resonant vibrations of the handling rod can be avoided easily.
摘要翻译：在植物切割装置中，操作杆（11）包括外管部分（71），内管部分（72）以及将外管部分和内管部分相互连接的三个径向支撑部分（73,74,75）。三个支撑部分（73,74,75）围绕杆的轴向中心线（P1）以不等角度间隔布置，使得三个支撑部分（73,74,75）之间形成的角度（θ1，θ2，θ3）彼此不同。因此，杆具有关于轴向中心线不对称的横截面构造。这样构成的操作杆的几何惯性矩在围绕轴向中心线的所有角度位置中取不同的值，因此杆的固有振动频率在所有角度位置也取不同的值。因此，杆的固有振动频率与仅在一个角度位置从驱动源单元传递的振动频率一致，从而可以容易地避免操纵杆的共振。
