A rolling bearing includes rolling elements incorporated between an outer race and an inner race, a resin seal ring covering the opening of at least one end of the bearing space, and a filter covering an oil hole formed in the seal ring for capturing foreign matter contained in lubricating oil. The filter and the resin seal ring are integrated by insert molding. The filter and the seal ring are made of the same material. An annular lip portion, which is separate from the seal ring, is in contact with the outer race. An engaged portion provided on the radially inner side of the seal ring is engaged in a recess formed in the inner race such that, during thermal expansion of the seal ring, the engaged portion is engaged such that the seal ring is movable in the radial direction relative to the inner race.

A rolling bearing is provided wherein one open end of a bearing space formed between an outer race and an inner race is covered with a sealing ring provided with oil flow holes provided with filters. The sealing ring includes engaging portions provided on the sealing ring in a protruding manner along a circumferential direction thereof, and engaged in recesses provided on the inner race. An annular member made of a material softer than that of the sealing ring is fixed to the sealing ring. The annular member includes a lip portion facing the outer race with a gap or kept in contact with the outer race. The sealing ring is formed by injection molding a resin, and weld lines generated during the injection molding are formed in portions of the sealing ring corresponding to radial directions along which the oil flow holes are not disposed.

An inverter circuit is configured with a reduced number of components for driving a plurality of discharge tubes. Primary coils of a plurality of drive transformers are respectively connected in series to primary coils of corresponding balancer-transformers, and then connected between output terminals of a switching circuit in parallel. The secondary coils of the balancer-transformers are connected in series, and connected between the output terminals of the switching circuit to configure an inverter circuit for driving a plurality of discharge tubes. The inverter circuit includes a voltage detecting circuit for detecting a voltage at any of connecting-midpoint of the series-connected secondary coils of the balancer-transformers, and a voltage comparing circuit for comparing an output of the voltage detecting circuit with a reference voltage. A signal designates an abnormal operation at an output of the voltage comparing circuit when the voltage of the connecting-midpoint exceeds the reference voltage.

Vehicles, such as all terrain vehicles, can be provided with a frame and a fender assembly. The fender assembly can have layered fender panels attached together with a bolt and T-nut. A channel can be formed between the fender panels to facilitate passage of fluid along a predetermined pathway. A seat includes a compression surface for sandwiching the fender assembly with respect to the frame. Front and rear fender assemblies can be attached to the frame by a midpoint fastener passing through respective apertures in each of the front and rear fender assemblies, through a grommet, and into the frame. A stay assembly attaches a mudguard to the fender assembly, and can involve a swivel clip. Methods are also provided.

The present invention provides a load failure protection circuit and a discharge lamp driving apparatus, which can exactly detect a failure even if the failure arises in any of a plurality of discharge lamps, and can stop drive of the discharge lamp. A part of currents of corresponding CCFLs (201 and 202) flows into two bypass resistors (21a and 21b), further, a full current of the bypass resistors (21a and 21b) flows into a resistor for full current detection (22), and its voltage drop is inputted into a control IC (1) as a feedback signal. On the other hand, cathodes of Zener diodes (25a and 25b) are connected to end parts of the bypass resistors (21a and 21b) on each CCFL side. When potential of any one of the cathodes rises by a load failure, a corresponding one of the Zener diodes (25a and 25b) generates a Zener voltage for a transistor (26) to become conductive. Therefore, since a feedback signal line connected to the collector of the transistor (26) is made at the ground potential forcibly, it is decided to be a load failure by the control IC (1), and drive of the discharge lamp is stopped.
