Abstract: This clip is used for, for example, attaching and constraining one member to the other member in a detachable manner, and is provided with a head disposed so as to block off a through hole of one of the members among through holes formed through the two members, and a leg which is inserted in the through hole, and which engages the back side of the other member. The clip is at least provided with a first member having a head, a suction part protruding from the circumference of the head, and an insertion hole in the axial direction, and a second member having a head overlaid so as to have a watertight structure with the head of the first member, and the leg formed perpendicularly with respect to the head, and inserted in the insertion hole.

Abstract: In an apparatus for determining failure of a double-clutch automatic transmission having a line pressure-regulating valve, pressure-regulating valves and select valves, it is determined whether the pressure regulated by the line pressure-regulating valve is equal to or greater than a predetermined pressure and it is determined that the line pressure-regulating valve has failed if the pressure regulated by the line pressure-regulating valve is determined to be less than the predetermined pressure, whereas it is determined that one from among the pressure-regulating valves and select valves has failed if the pressure regulated by the line pressure-regulating valve is determined to be equal to or greater than the predetermined pressure.

Abstract: An apparatus for determining failure of an automatic transmission having gear engaging mechanisms engaging one of gears to input shafts and an output shaft, a first to third pressure-regulating valves, a first and second shift valves, and a failure determiner. The failure determiner energizes a solenoid valve to output a clutch pressure to one of the gear engaging mechanisms when the clutch pressure is less than a prescribed pressure, determines whether the one of the gear engaging mechanisms operates based on output of an operating state detector, and determines that the second pressure-regulating valve has failed when the one of the gear engaging mechanisms is determined to be inoperative.

Abstract: A hydraulic coupling device includes left and right vane pumps which discharge working oil in response to the relative rotation of main driven wheels and left and right subsidiary driven wheels. First orifices are defined in a side plate disposed between the left and right vane pumps to permit communication between intake ports and discharge ports in the vane pumps. Orifices are defined in the side plate to permit communication between the intake ports and between the discharge ports in the vane pumps. With the above arrangement, in a hydraulic coupling device of a power transmitting system in a four-wheel drive vehicle, the formation of the orifices can be easily carried out, and the characteristics of the orifices can be stabilized.
