Abstract: A failure diagnostic device for an exhaust gas recirculation (EGR) apparatus, which can detect an intake pipe pressure at a high accuracy with a simple control and can prevent false diagnosis of an EGR system. If at least either one of first and second off-mode intake pipe pressures P1off, P2off exceeds a cancel determination value K, an ECU determines that the intake pipe pressures P1off, Pon and P2off are not properly detected, and cancels the failure diagnosis of the EGR system. Therefore, the false diagnosis of the EGR system can be avoided with a simplified process without requiring specific determinations on individual abnormal states of the various components other than the EGR system. By setting the cancel determination value K based on the intake pipe pressure P resulting when EGR off-control is executed in a state of an EGR valve being stuck in a fully-open position, each improperly-detected intake pipe pressure can be excluded with reliability.

Abstract: A bearing apparatus for a vehicle driving wheel which prevents generation of stick-slip noise as well as fretting wear to improve durability of the bearing apparatus has an outer member (10) formed with double row outer raceway surfaces (10a, 10a) on its inner circumferential surface. An inner member (1, 27) is formed with double row inner raceway surface (2a (24a), 3a) opposite to the double row outer raceway surfaces (10a, 10a). Double row rolling elements (6) are freely rollably maintained between the outer and inner raceway surfaces (10a, 10a; 2a (24a), 3a), respectively, of the outer and inner member (10; 1, 27). A constant velocity universal joint (11, 26), for torque transmission, is inserted into the inner member (10; 1, 27). The constant velocity universal joint abuts and is axially separably connected to the inner member via a nut (19).
