Monitor and working vehicle provided with the monitor

A monitor installed near an operator's seat of a working vehicle, the monitor comprising:

• a display provided by a liquid crystal display;
• a circuit substrate that is electrically connected to the display;
• a first connector that is installed on the circuit substrate and is configured to be connected to a second connector of an exterior cable;
• a resin-made exterior case that houses the display and the circuit substrate;
• and
• a connector attachment portion that is provided on a planar portion of the exterior case opposed to the circuit substrate, the connector attachment portion defining a space that is dented from the planar portion toward the first connector, wherein
• the connector attachment portion comprises an opening through which the first connector protrudes such that an end of the first connector is exposed to an outside of the exterior case,
• at least a part of an inner circumferential surface of the connector attachment portion is an inclined surface portion that is enlarged toward the planar portion from the opening,
• an installation side of the first connector to the circuit substrate is disposed in an inner space of the exterior case,
• the planar portion is defined as a back face,
• the connector attachment portion comprises:
• a rear opening that is open on the back face;
• and a side opening that is open at a position on a side face opposed to the inclined surface portion, the side face defining a box shape with the back face, and is in communicative connection with the rear opening,
• the side opening is partially closed by a side wall that is flush with the side face, and
• the display is provided by a liquid crystal display having a display surface surrounded by control buttons disposed in an L shape.
