    • A linear actuator includes a driving part having an inner yoke, an outer yoke and a coil for generating an alternating magnetic field and includes a movable body provided with a magnet disposed between the inner yoke and the outer yoke. The movable body is formed in a tubular shape having an aperture edge part at least one end is opened, and the aperture edge part or a portion near the aperture edge part disposed between the inner yoke and the outer yoke is positioned closer to the inner yoke side than to the outer yoke side. Alternatively, the linear actuator may includes an expansion preventing member which is disposed at the aperture edge part or the portion near the aperture edge part for preventing the aperture edge part from expanding.

    • A linear actuator includes a driving part provided with an inner yoke and an outer yoke, a magnet disposed between the inner yoke and the outer yoke, and a movable body which is to be driven to reciprocate in the axial direction. The driving part includes a coil for generating an alternating magnetic field in a first gap space and a second gap space which are formed between the inner yoke and the outer yoke. The movable body is interlocked and driven with the alternating magnetic field. The driving part further includes a coupling means disposed along the axial direction in a gap space which is formed by the outer yokes adjacent to each other in a circumferential direction or by the inner yokes adjacent to each other in the circumferential direction. The coupling means connects the driving part to a main body part side which is provided with a moved body that is driven by the movable body.
    • 线性致动器包括设置有内磁轭和外磁轭的驱动部,设置在内磁轭和外磁轭之间的磁体,以及被驱动以沿轴向往复运动的可动体。 驱动部分包括用于在第一间隙空间中产生交变磁场的线圈和形成在内磁轭和外磁轭之间的第二间隙空间。 可动体由交变磁场互锁并驱动。 驱动部还包括沿着轴向设置在由圆周方向上彼此相邻的外轭或沿圆周方向彼此相邻的内轭构成的间隙中的联接装置。 联接装置将驱动部件连接到主体部分侧,主体部分侧设置有由可移动体驱动的移动体。

    • A lift device, comprising link units and a drive source, for operating these link units, is provided on the top of a vehicle or high surface. The link units comprise a telescoping arm that is disposed in a reclined posture on a top of the vehicle or high surface, a boom that is swung up and down by the drive source, a slide beam that is moved by the swing movement of this boom, along the top of the vehicle or high surface, and arm telescoping means for telescoping the telescoping arm in response to the swing movement of the boom. The telescoping arm comprises a first arm member, having an end that is rotatably connected to a free end of the boom, and a second arm member that is mobile in the lengthwise direction of the first arm member, the first arm member being oriented upwards so as to be lowered while extending from the top of the vehicle, as a result of the swing movement of the boom.
