  • Publication number: 20140325861
    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.
