A lever device includes a base, a movable body supported on the base rotatably about a first lateral shaft, a lever supported by the movable body and pivotable between a depressed position and a raised position, a cam body including a cam groove, the cam body being supported on the movable body rotatably about a second lateral shaft and configured to rotate about the second lateral shaft as the lever is pivoted, and first and second guide members attached to the base and inserted in the cam groove, the guide members being configured to change their position relative to the cam groove as the lever is pivoted. The cam groove includes a first groove portion where the first guide member is positioned when the lever is in the depressed position, and a second groove portion where the second guide member is positioned when the lever is in the depressed position.

Lever device and working machine including the same

The disclosed art includes: a machine body; an operator's seat mounted on the machine body and including a seat part and a backrest part; a manipulator base disposed on a lateral side of the operator's seat; and a housing body for housing a printed material therein, and the housing body is disposed forward of the backrest part and on the opposite side of the manipulator base from the operator's seat.

Housing body and working machine

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).

Lever device and working machine

A working machine includes a machine body an operator seat mounted on the machine body, a front working device swingable upward and downward, the front working device being provided forward of the operator seat and on one side in a machine-width direction eccentric with respect to a central portion of the operator seat, and a front guard provided forward of the operator seat. The front guard includes a first frame member provided forward of the operator seat and on the one side, and a second frame member provided forward of the operator seat and on another side opposite to the one side, the first frame member includes a main rod portion defining upper and lower portions of the first frame member, extending between the upper and lower portions of the first frame member, and provided rearward of the front working device, and the main rod portion is formed to be positioned in a machine fore-and-aft direction closer to the operator seat than the second frame member.
