The operation handles 10 and 10a described above may be used as a handle by being connected to a pipe to the driving operation unit 11 in which various operation buttons are installed so as to operate driving of the equipment.

When the user grasps the bar-shaped left and right handles 14 and the user pulls the bar-shaped handle 14 toward the user or pushes the bar-shaped handle 14 toward the user or in a direction opposite to the user (away from the user), the frame Handles 14 whose lower ends are pivotally fixed to 12 are pivoted about the pivot pin a as a central axis, respectively.

That is, the upper end of the aforementioned handle 14 flows in the cutout 15 cut out in the holder 16 fixed to the frame 12. At this time, the pressing surface of the protrusion 13 formed at the upper end of the handle 14 is in contact with the thin plate-type pressure sensor 17 installed on the inner surface of the cutout 15 in proportion to the grip force of the user.

Therefore, the pressure sensor 17 detects the operation direction (referring to the rotation direction) and the pressing force (referring to the grip force) of the handle 14 respectively operated by the user. As the detected signal is converted into an electrical signal and transmitted to the controller through the signal cable 20, the driving motor (not shown) is driven by a control signal transmitted from the controller to the driver.
