Patent ID: 8578808

Claim:
An operation device comprising: resistor holding means for holding a resistor; a movement member which is in contact with the resistor that is held by the resistor holding means, and includes a movement portion that is movable relative to the resistor; a pivotal section which is disposed at a position different from a movement plane in which the movement portion moves, and is pivotable about a predetermined pivotal axis; an operation shaft which extends from the pivotal section through the movement plane, and includes an operation portion which is operable by an operator; an engaging section which includes an engaging hole portion in which the operation shaft is advancibly/retreatably engaged; a coupling portion which couples the engaging section and the movement portion of the movement member in a direction at an acute angle to a direction of extension of the operation shaft; movement amount detection means for detecting a movement amount of the operation shaft; and driving means for executing driving on the basis of a detection result of the movement amount detection means.
