摘要： A force-sense-imparting operation device including a stationary section, a rotating section, and an operation member. One of the stationary section and the rotating section includes an excitation coil and a first magnetic pole section, and the other includes a second magnetic pole section capable of opposition to the first magnetic pole section in a specific opposing direction. The first magnetic pole section forms a magnetic circuit with the first magnetic pole section due to the second magnetic pole section being excited in a state that the second magnetic pole section opposes the first magnetic pole section. The magnetic circuit encircles a periphery of the excitation coil on the cross section, the second magnetic pole section being arranged to separate from the first magnetic pole section with rotation of the rotating section.

The boom comprises a first supporting portion configured to rotatably support a jib foot when the jib is set in a protruding posture; and a second supporting portion configured to rotatably support a supportable portion of the jib when the jib is set in an enfolded posture. A position adjusting and holding unit of the jib is configured to couple, to the frame, a specific site of the second link in such a manner that a relative position of the second link with respect to the frame in a rotational direction of the second link is adjustably changed to allow the rotational axis of the second joint portion to become coincident with the rotational axis of the jib foot, and to hold the second link at the changed relative position.
