Abstract: An air pump device includes an electric pump unit including a pump mechanism and a motor configured to drive the pump mechanism, a case housing the electric pump unit, and a vibration-proof member interposed between the electric pump unit and the case. The vibration-proof member is a plate-shaped member made of an elastic resin material and is wound around the electric pump unit to wrap the electric pump unit therein. A part of the vibration-proof member is sandwiched between the electric pump unit and one of facing surfaces that are inner surfaces of the case and face each other inside the case. Another part of the vibration-proof member is sandwiched between the electric pump unit and the other one of the facing surfaces.

Abstract: An oil inspection device for a work vehicle includes a conduit pipe, a projecting pipe, and an oil inspection tube. A dipstick is used to check the lubricating oil level in the oil inspection device. The conduit pipe has an oil inspection component where oil is checked and conducts the lubricating oil from a reservoir space to the oil inspection component, the reservoir space holding the lubricating oil. The projecting pipe is provided to the conduit pipe and faces upward from the oil inspection component. The oil inspection tube has a connector with a hexagonal prism shape. The connector is removably connected to the projecting pipe and disposed on an outside of the projecting pipe. The oil inspection tube is configured to have the dipstick inserted.

Abstract: The invention has an object to reduce a manufacturing cost of a closed electric compressor for discharging a carbon dioxide refrigerant into a sealed container by manufacturing at a low cost a high pressure resistant terminal used in the compressor. In a rotary compressor as the closed electric compressor including an electrical drive element and a rotary compression mechanism section (compression element) consisting of a first and a second rotary compression element driven by the electrical drive element in a sealed container to discharge the carbon dioxide refrigerant compressed by the second rotary compression element into the sealed container, the rotary compressor has a terminal mounted on the sealed container for supplying electric power to the electrical drive element and constituted by electrical terminals and a terminal body formed by low pressure forging.
