A grommet is mounted on a wire harness and inserted and latched into a vehicle panel aperture having a circular arc section at each corner. The grommet has a small tubular portion and a large tubular portion fitting the aperture. The large tubular portion has an annular latch groove having a concave shape on an outer peripheral surface at a predetermined distance from an end. Of two side walls that sandwich a groove base of the latch groove, a first side wall has a height from the groove base greater in straight sections than in arc sections to allow the straight sections to catch a periphery of the aperture more deeply than the arc sections.

A light-emitting element substrate mounting light-emitting elements is arranged on a front face of a chassis. The light-emitting element substrate is connected to a first connector. A power supply substrate for supplying electric power to the light-emitting element substrate is arranged on a rear face of the chassis. A second connector is connected to the power supply substrate. In addition, the first and the second connectors are connected to each other, so that the power supply substrate supplies electric power to the light-emitting element substrate via the first connector and the second connector. The second connector may electrically be connected to the power supply substrate via a harness.

The present invention is designed to provide an insulation coil with high insulation reliability using a dry mica tape, an integral impregnation coil and a mica tape for the electrical rotating machines using these coils, said mica tape having a long shelf life and capable of preventing run-off of the impregnating epoxy resin composition during curing, with the cured product of said epoxy resin composition being high in heat resistance. It is also envisaged to provide a single insulation coil using a mica tape containing epoxy adduct imidazole as an epoxy resin curing catalyst or a mica tape containing a mixture of epoxy adduct imidazole and zinc naphthenate. An integral impregnation coil made by using said insulation coil and an epoxy resin composition, and the electrical rotating machines using such coils are also provided.

A fixed constant velocity universal joint is made compact, has little decrease in load capacity even when the fixed constant velocity universal joint is made compact and is at an operating angle, and has improved high angle strength and durability through lessening instances in which a ball runs over a track at a high angle. In the fixed constant velocity universal joint, a cage includes four pockets, the pockets including a pair of long pockets of which a circumferential direction spacing is wide and a pair of short pockets of which the circumferential direction spacing is narrow. The pair of long pockets are shifted by 180 degrees along a circumferential direction and the pair of short pockets are shifted by 180 degrees along the circumferential direction. As a result, the long pockets and the short pockets are alternately disposed along the circumferential direction. A long pocket houses two balls. A short pocket houses one ball. Two ball housing sections connected by a slit are formed in the long pocket by projections that project towards a long pocket inner side being provided on opposing long sides of the long pocket.

A slot insulating paper (12) is arranged in a slot (18) of a core (10) of an electric motor or generator. In a state where the slot insulating paper (12) is spread in a sheet shape, a region (high stiffness portion (36)) that is part of the slot insulating paper (12) is a breakage resistance portion having a higher resistance against breakage than the other region (ordinary portion (38)). The slot insulating paper (12) may be formed by laminating a plurality of insulating layers. In the breakage resistance portion, for example, at least one of the laminated insulating layers is a high stiffness layer formed of a high stiffness material. Thus, the breakage resistance portion is formed to have a high stiffness. With a high stiffness, it is possible to improve breakage resistance.
