Abstract: A rotating electric machine includes a stator core, a stator coil formed of electrical conductors and insulating coats respectively covering the electrical conductors, and an encapsulating resin body. The stator coil has a coil end part protruding from the stator core. The coil end part includes exposed portions of the electrical conductors, which are exposed from the insulating coats, joints formed at the exposed portions, and covered portions of the electrical conductors which are covered with the respective insulating coats and respectively adjoin the exposed portions. The encapsulating resin body has a first part in which the exposed portions of the electrical conductors and the joints are encapsulated, and a second part in which at least part of each of the covered portions of the electrical conductors is encapsulated. A coefficient of linear expansion of the first part is lower than a coefficient of linear expansion of the second part.

Abstract: A release device for a clutch including a cylinder aligned coaxially with a release bearing, a cylindrical piston adapted to fit in a cylindrical operation chamber of the cylinder, and an annular packing mounted adjacent an annular end of the piston within the operation chamber, the operation chamber being connected to an external operating pressure control device through a liquid pressure control passage, the piston being axially connected, at its one end positioned outside the operation chamber, to the release bearing, wherein an annular slide member is fixed to an end of the packing which adjoins the piston, the slide member being greater in hardness than the packing and lower in friction coefficient against the piston than the packing.
