The center cover portion includes a punching metal and has a substantially rectangular shape. A first side and a second side of the rectangular shape face each other in a width direction, and a third side and a fourth side of the rectangular shape face each other in a front-rear direction. The first side cover includes a punching metal, has a substantially rectangular shape, is connected to the center cover portion at the first side, and is inclined downward in the height direction relative to the center cover portion. The second side cover includes a punching metal, has a substantially rectangular shape, is connected to the center cover portion at the second side, and is inclined downward in the height direction relative to the center cover portion.

A canopy of a dump body for a truck comprises a deck having a length and a width greater in dimension that the length defined by a front edge, a rear edge opposite the front edge, a first side edge, and a second side edge opposite the first side edge. The deck can define an upper surface and a lower surface opposite the upper surface. In a front view the deck can define a concave shape, with a center portion and stepped portions between the center portion and the first and second side edges.

Provided is a waterproof structure to prevent water ingress through an air hole in a casing of a communication device. A waterproof structure for a communication device, the communication device including a casing that houses an electronic substrate and has an air hole, includes a plate member facing the casing and attached to the casing such that the plate member covers the air hole, and a sealing member interposed between the plate member and the casing to prevent ingress of water into the air hole through a gap between the plate member and the casing.

The front pillar disposed on the second side face of the cab is located behind the front pillar disposed on the first side face of the cab. The boom mounting bracket and the front pillar overlap each other in a side view.

A shovel includes a lower traveling body, an upper turning body turnably mounted on the lower traveling body, an attachment attached to the upper turning body, a cabin mounted on the upper turning body, and a protection member configured to protect the cabin. The protection member is provided on the attachment or the upper turning body at a position corresponding to the front of the cabin.

A protective canopy includes a canopy body, which is switchable between a first position and a second position, a canopy base, a first linkage and a second linkage for connecting the canopy body to the canopy base, each of the first linkage and the second linkage is pivotally connected to both the canopy body and the canopy base, respectively, and pivot axes formed at the pivoting connection positions between each of the first and second linkage and each of the canopy body and the canopy base are parallel to each other, such that the canopy body is switchable relative to the canopy base between the first position and the second position by manipulating the first and/or second linkages and/or the canopy body. An earth working machine having such protective canopy and a method for changing position of a protective canopy of earth working machine are also disclosed.

To provide a stowing device, cab, and working machine, that may hardly make an operation cabin dirty by something stored such as outdoor shoes and prevent something stored from being made dirty or lost. A stowing device is disposed accessibly from behind an operator's seat in an operation cabin on an inside of a cab comprising an entrance at a back part and comprises a stowing part capable of storing something. As it is possible to store outdoor shoes in the stowing part (40) and change into indoor shoes when getting on the operation cabin through the entrance, the operation cabin will be hardly made dirty by the dust attached on the outdoor shoes and others. As something such as outdoor shoes may be stored in the cab, something stored will not get dirty in the rainy weather and be prevented from being lost during work.

A vehicle includes a frame, and at least one front and rear wheel. The total number of front and rear wheels is at least three. The vehicle includes a mechanism for driving at least one of the front and rear wheels, a seat for a driver, and at least one fall prevention element to prevent, in a closed position of the fall prevention element, a driver from falling off the seat. In an open position of the fall prevention element, a driver can freely take a seat from the outer side of the vehicle via the space which, in the closed position, is occupied by the fall prevention element, or can step out of the vehicle; the fall prevention element slides between the open and closed positions.

A remote operation support device 100 is provided that is for improving the work efficiency of a remote operation performed by an operator, without fogging a front window 425F of a work machine 40 that is remotely operated by the operator. The remote operation support device 100 includes: a meteorological data obtaining unit 103 that obtains meteorological data at a designated time; an intra-cab temperature estimation unit 104; an intra-cab humidity estimation unit 105; a fogging determination unit 106; and an anti-fogging control unit 107. The anti-fogging control unit 107 performs an anti-fogging process for preventing the front window 425F from being fogged when a determination result by the fogging determination unit 106 is affirmative.

A working machine includes: a lower traveling body; an upper slewing body; a cab; a display device; and a detector. The upper slewing body is slewably mounted on the lower traveling body. The cab is mounted on the upper slewing body. The cab include: a front wall having a front window; a pair of left and right front pillars extending in an up-down direction respectively along left and right sides of the front window; and a pair of left and right side walls extending reward respectively from the left and right front pillars. The display device is disposed in a corner defined between one of the left and right side walls and the front wall in the cab while being fixedly attached to the one side wall or the front wall for displaying predetermined information. The detector is fixedly connected to the display device.
