A manipulating device is provided, which includes a first parallel linkage mechanism having a pair of first links and a pair of second links, a second parallel linkage mechanism having a pair of third links and a pair of fourth links, and a support member supporting one of the third links. The first parallel linkage mechanism and the second parallel linkage mechanism commonly use one of the second links and one of the fourth links and an armrest member to which a manipulating member is attached at a tip-end part thereof is disposed in a lower-end part of the first parallel linkage mechanism.

An operation device includes an operation unit including an operation body worked by an operator's manipulation; a position detecting part detecting a position of the operation body; and a display unit displaying a position of the operation body. The display unit includes an operation member, a supporting body, and a movable load applying mechanism including a movable member, a magnetic generating mechanism, a magnetorheological fluid, and an operation controlling part. The display unit includes a display part displaying the operation position. A display controlling part PS controls a display. A controller is included to control the operation controlling part and the display controlling part. In a control method of the operation device, the controller controls to display a state of the operation position of the operation body on the display part.

In a shift device, the placement of magnets relative to sensors can be changed by rotating a ball shaft of a lever. The sensors detect magnetic fields generated by the magnets in order to detect a shift position of the lever. Shields suppress a magnetic field outside the ball shaft from reaching the sensors. The magnets, the sensors, and the shields are disposed on the ball shaft. This enables a reduction in the size of the shift device.

A knob assembly includes a front panel, a knob located at a front side of the front panel and configured to rotate based on operation by a user, a knob shaft that is coupled to the knob and that extends through the front panel, a supporting pipe that receives the knob shaft and that supports the knob shaft, the supporting pipe being configured to maintain a position relative to the front panel, a valve configured to control supply of gas to the appliance, a valve shaft connected to the valve and configured to control the valve to adjust a flow rate of gas based on rotation of the valve shaft, and a joint that couples the knob shaft to the valve shaft and that is configured to transfer at least one of a rotational motion or a linear motion of the knob shaft to the valve shaft.

An insulated joystick for use in an insulated environment, such as on an insulated aerial device. The insulated joystick includes an inner assembly segment, a mobile sensor, and an outer protective segment. The inner assembly segment presents a sensor void and is formed of a dielectric material. The mobile sensor is disposed at least partially within the sensor void. The mobile sensor is configured to detect a movement of the insulated joystick by a user. The outer protective segment disposed at least partially around the inner assembly segment and is formed of a dielectric material.
