A fluid mixing device includes a hollow tubular main body () to mix an exhaust gas (G) and a warming gas (G) within it, a first inflow port () provided in an upstream end portion of the main body () and through which the exhaust gas (G) flows, a mixing promotion body () of a tubular shape disposed inside the main body () and having a longitudinal axis (C) extending in a direction conforming to a direction of flow of the exhaust gas (G), and a second inflow port () provided in a peripheral wall of the main body () and through which the warming gas (G) flows towards an outer peripheral wall of the mixing promotion body (). The exhaust gas (G) flows outside and inside the mixing promotion body ().

A planetary gear device includes: a sun gear; a plurality of planet gears that mesh with the sun gear; and a baffle unit disposed in a circumferential gap between the adjacent planet gears. The baffle unit includes: a first introduction opening portion open in a radially inward direction to introduce lubricating oil, which has lubricated the sun gear and the planet gears, into the baffle unit; an end wall forming one end in an axial direction of the first introduction opening portion; a discharge opening portion to discharge lubricating oil in the baffle unit; and a guide portion disposed at a side portion of the baffle unit on a rear side in rotation direction of the sun gear, and configured to cover the first introduction opening portion in the circumferential direction and to guide the lubricating oil to an outer circumference of the adjacent planet gears.

A sealing member has a first portion. The first portion has a central axis, a first peripheral surface extending in a direction parallel to the central axis, and a central aperture. A first wall portion of a groove has a recess communicated with the first opening of the first channel. The recess has a second peripheral surface complementary to the first peripheral surface of the first portion of the sealing member. The first portion of the sealing member moves radially toward and away from the rotational axis as the first peripheral surface of the sealing member defines and maintains a first sealing contact with the second peripheral surface of the recess. The sealing member moves radially outwardly and thereby makes a second sealing contact surrounding the second opening of the second channel to establish a communication between the first and second openings.
