The present invention is intended to provide a metal gasket material plate with which exfoliation of the coating or blister can be prevented even if it is used in the presence of an electrolyte aqueous solution and which can be manufactured through a process without use of hexavalent chromium in consideration of the environment, etc. The present, invention relates to a metal gasket material plate comprising a metal platehaving a rubber layeron one side or both sides thereof through an adhesive layer, wherein a rust-resistant pigment is added to both of said adhesive layerand said rubber layer

Metal gasket material plate and method for manufacturing the same

An intercooler has a case through which supercharging air passes, and a heat exchangermounted inside the case which allows heat exchange between the supercharging air and a cooling fluid. A frame bodyis provided at the circumferential edges of air passage portions of the heat exchangeron a supercharging air intake side and a supercharging air outlet side to reduce the gap between the heat exchanger and the inner wall of the case. The heat exchangerhas a pair of tanksand, tubes communicating between the tanks, and a plurality of finsset along the tubes, and assumes a structure that allows the supercharging air to pass through the heat exchanger a plurality of times by sequentially passing through blocks formed by dividing a heat exchanging unitA into a plurality of blocks with partitioning plates

Intercooler

In order to provide an intercooler assuming a simple structure that enables cooling of supercharging air and absorption of any expansion/contraction of the cooling water pipe and the casing attributable to the heat of the supercharging air, intake/outlet pipes of a heat exchanger housed inside a cooling space formed within a case are inserted at cylindrical pipe insertion portions formed at the case, and any gap present between the intake/outlet pipes and the insertion portions are sealed by seal members each constituted of an elastic material formed in a staged cylindrical shape having a first cylindrical portion placed in complete contact with one of the pipe insertion portions and a second cylindrical portion placed in complete contact with either one of the intake/outlet pipes, which are also utilized to fit the heat exchanger in the case with a gap.

To easily perform a change between a four-wheel drive operation of a vehicle to a two-wheel drive operation of the vehicle. In a four-wheel buggy having the four-wheel drive specification in which a longitudinally mounted engine with a crank shaft is directed in the longitudinal direction of the vehicular body, an output shaft is divided into a main body portion and a front wheel connection portion. In the case of applying the output shaft structure to the four-wheel drive specification, a male spline formed on a front end portion of the main body portion is fitted in a female spline formed in a rear end portion of the front wheel connection portion. A front end portion of the front wheel connection portion projects forwardly from an outlet portion of a front case cover, and is connected to a front wheel propeller shaft. On the other hand, in the case of applying the output shaft structure to the two-wheel drive specification, the output shaft composed of only the main body portion to which the front wheel connection portion is not connected, can be commonly used, and the outlet portion of the front case cover may be left as cast, that is, without formation of the through-hole. Accordingly, it is possible to easily perform a change between the four-wheel drive specification and the two-wheel drive specification by commonly using the power unit case, except that only the front case cover requires a slight modification for the four-wheel drive specification.

Output shaft structure for shaft drive vehicle

To reduce the size and weight of an oil tank for a dry sump type lubricating system. A separate oil tank of a dry sump type lubricating system is mounted on the front surface of a front case cover constituting part of a crankcase divided into front and rear parts. An effective volume portion, in which oil supplied from the crankcase side via scavenging pumps and cooled by an oil cooler is contained, is provided in the oil tank. The bottom portion of the effective volume portion is connected to a feed pump on the crankcase side via an outlet side passage. A tank side pipe portion extending rearwardly through the oil tank is integrally provided at a portion of the oil tank higher than the oil level in the oil tank. The tank side pipe portion is connected to a crankcase side pipe portion integrally provided on an upper portion of the front case cover to form an overflow passage. The overflow passage functions as a pressure-equalization passage for equalizing the pressure in the oil tank with the pressure in the crankcase, and allows overflowed oil in the oil tank to readily flow into the crankcase through the upper portion of the front case cover.
