Abstract
A first crank supports an operating stick so as to be pivotable in a first direction. First flat faces are formed at lower both end portions in the first direction of the first crank. A second crank supports the operating stick so as to be pivotable in a second direction which is perpendicular to the first direction. Second flat faces are formed at lower both end portions in the second direction of the second crank. A restoration member is arranged coaxially with the operating stick which is situated at a neutral position thereof. The restoration member includes a flat top face brought into contact with the first flat faces and the second flat faces. A spring member is arranged coaxially with the restoration member, and urges the restoration member toward the first flat faces and the second flat faces.
