Abstract: A working machine includes an operator's seat, a seat base supporting the operator's seat, and a slide rail for adjustment of a position of the operator's seat, the slide rail being located between the seat base and the operator's seat, in which the seat base includes a rail mount for attachment of the slide rail, the rail mount having a downward convex curve which is curved to deviate from the slide rail with increasing distance from each of opposite ends of the rail mount in a longitudinal direction of the slide rail and with decreasing distance to a center of the rail mount in the longitudinal direction.

Abstract: A lever device includes a movable bracket and a lever supported on a support shaft on a base such that they are pivotable between lowered and raised positions, first engagement portion(s) on the movable bracket, second engagement portion(s) on the lever, a cam member attached to the support shaft such that it is movable in an axial direction of the support shaft but not rotatable about the support shaft, and a biasing member to bias the cam member to engage with the first and second engagement portions. When the movable bracket etc. are in the lowered position and when they are in the raised position, the first engagement portion(s) engage(s) with the cam member to restrict the movable bracket from pivoting. When the lever pivots upward from the lowered position or downward from the raised position, the second engagement portion(s) disengage(s) the cam member from the first engagement portion(s).

Abstract: A working machine includes a machine body, a cabin on the machine body, an air conditioner body for air conditioning in the cabin, and a prime mover room to contain a prime mover on the machine body. The air conditioner body is disposed above the prime mover room.

Abstract: The working machine includes an operator seat, an armrest arranged adjacent to the operator seat, an operation lever arranged in front of the armrest, and a jug dial arranged adjacent to the operation lever. The jog dial is arranged on a position allowing an operator seated on the operator seat to operate the operation lever and the jog dial with an arm placed on the armrest.
