    Abstract: A toroidal continuously variable transmission including a power roller; a support supporting the power roller rotatably; a thrust bearing receiving a load of the power roller in a direction along a rotating axis; and an oil passage supplying lubricating oil to the thrust bearing. A surface of the power roller opposing the support includes a first bearing grooved and the support opposing the power roller includes a second bearing groove. A virtual axis of a discharge port in the oil passage reaches a bearing groove that is one of the first bearing groove and the second bearing groove. Viewed from a direction perpendicular to the rotation axis, a portion of a retainer located at a radially inner side of a retaining hole of the retainer and a portion located at a radially inner side of the bearing groove are located at sides opposite to each other across the virtual axis.

    Abstract: 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.

    Abstract: A gas turbine engine including: an exhaust diffuser including an inner tube and an outer tube that form therebetween an annular exhaust passage; a bearing chamber formed radially inside the inner tube for accommodating a bearing that supports a rotor of a turbine; a plurality of hollow struts extending across the exhaust passage; an oil introduction passage extending through one of the struts for introducing oil to be supplied to the bearing chamber; an oil drain passage extending through one of the struts for draining the oil from an exhaust oil inlet opened on a bottom surface of the bearing chamber; and an oil discharge passage for discharging a portion of the oil having passed through the oil introduction passage toward the oil drain inlet.
