Claim Text:
1. An operation device comprising: an operation member displaceable by an operator; a two-dimensional support mechanism in which a pair of one-dimensional support mechanisms that individually displaceably supports the operation member in mutually crossing two directions are connected in series; and a pair of biasing mechanisms that individually biases the operation member toward a neutral position of displacement by each of the one-dimensional support mechanisms, wherein biasing forces that the pair of biasing mechanisms applies to the operation member against displacement of the operation member are different, and wherein a command signal according to the displacement of the operation member of each of the one-dimensional support mechanisms is output, wherein one of the one-dimensional support mechanisms includes a rail member that linearly movably supports the operation member along either of the two directions, wherein the other one-dimensional support mechanism includes a swing member that swingably supports the rail member around an axis line parallel to the rail member, wherein the biasing force that the one biasing mechanism biasing the operation member in a direction along the rail member applies to the operation member against the displacement of the operation member is larger than the biasing force that the other biasing mechanism biasing the swing member in a swing direction of the rail member applies to the operation member against the displacement of the operation member.
