A transmission device includes a casing accommodating a transmission gear and having an oil sump for retaining oil. The oil in the oil sump flows from a lubrication pump through a lubrication passage and is injected to the transmission gear. A connection portion is provided in a part of the lubrication passage, which part is disposed outside the casing. A direction control valve is provided downstream of the lubrication pump and upstream of the connection portion in the lubrication passage with respect to a flow direction of the oil. The direction control valve is configured to open the lubrication passage when a hydraulic pressure in the lubrication passage exceeds a predetermined value and to close the lubrication passage when the hydraulic pressure is equal to or lower than the predetermined value.
