A transmission device (1) includes a casing (2) accommodating a transmission gear (4) and having an oil sump (6) for retaining oil (OL). The oil (OL) in the oil sump (6) flows from a lubrication pump (8) through a lubrication passage (10) and is injected to the transmission gear (4). A connection portion (32) is provided in a part of the lubrication passage (10), which part is disposed outside the casing (2). A direction control valve (14) is provided downstream of the lubrication pump (8) and upstream of the connection portion (32) in the lubrication passage (10) with respect to a flow direction of the oil. The direction control valve (14) is configured to open the lubrication passage (10) when a hydraulic pressure (PI) in the lubrication passage (10) exceeds a predetermined value (VI) and to close the lubrication passage (10) when the hydraulic pressure is equal to or lower than the predetermined value (V1).
