A water-cooled internal combustion engine includes a water pump having a short pump drive shaft for reducing the weight and size thereof. In a water-cooled internal engine equipped with power transmission control means at the end of a crankshaft, a water pump having a water pump drive shaft parallel to the crankshaft is disposed on the axial inside of the power transmission control means, that is, on a central side of the crankshaft.

An epoxy resin composition for printed wiring boards which comprises an epoxy resin, a phenolic novolak, a curing accelerator, and a silica filler, characterized in that the silica filler has a shape having at least two planes and has an average particle diameter of 0.3 to 10 μm and a specific surface area of 8 to 30 m2/g. The epoxy resin composition has a higher apparent viscosity than the resins and can hence be inhibited from sagging in a drying oven. This composition retains the intact property of infiltration into reinforcements because the viscosity of the resins themselves has not increased locally. The composition hence produces the effect of improving the appearance of a prepreg.

A hydraulic continuously variable transmission with a fixed displacement type swash plate plunger pump and a variable displacement type swash plate plunger motor are connected to each other through a closed hydraulic circuit. A motor pivot member is supported to be pivotally movable in a support member. The motor pivot member includes an upwardly extending arm portion. The tip end of the arm portion is movable in the axial direction by a motor servo mechanism, to pivotally move the motor pivot member. A transmission housing is provided with an auxiliary portion surrounding the motor servo mechanism and the tip of the arm portion, and a servo motor is mounted to a side surface on one end side, in the direction of the axis of rotation of an output shaft. A side of the housing auxiliary portion, opposite the servo motor, includes an identification number display portion.

A power transmission apparatus for an engine of a vehicle. The apparatus includes a starting clutch for smoothly connecting rotation of a crankshaft to a transmission upon starting of the vehicle, a hydrostatic continuously variable transmission for performing speed change depending upon a capacity difference between a swash plate hydraulic pump and a swash plate hydraulic motor to transmit rotation of the crankshaft at a reduced speed to a driving wheel, and a slider for moving a ball screw back and forth to change the angle of the swash plate of the swash plate hydraulic motor. The starting clutch can be a torque converter.

To improve a mounting configuration for a chain guide of a cam chain for transmitting power to a power system of an internal combustion engine to make mounting of a chain guide and a cylinder block simple and easy. A mounting device for a cam chain guide for an internal combustion engines constructed such that rotation of a crank shaft is transmitted to a cam shaft provided externally of a cylinder bore by a cam chain 3 to operate an intake/exhaust valve through a push rod and a rocker arm. A first protrusion provided in the vicinity of a lower end of a chain guide is fitted into a first locating groove provided in the vicinity of a crank shaft of a crank casing, and a second protrusion provided in the vicinity of an upper end of a chain guide is fitted into a second locating groove provided in a lower surface of a cylinder block and gradually enlarged from a protrusion fixed position toward an opening.

In a power system for a vehicle, the line segment L connecting between the center O1 of a driving shaft (speed change shaft) of an oil hydrostatic non-stage transmission and the center O2 of a ball screw (ratio change driving shaft) of a ratio change mechanism is set parallel to the mating plane P of the crank case and the cylinder block, while the axis C2 of a detecting shaft is disposed coaxially with the turning axis C1 of a swash plate holder orthogonal to the line segment L, and, in this condition, a ratio detecting sensor is bolted to an upper wall. Wherein the axis C2 of the detecting shaft is set parallel to the cylinder axis C0, and the machining axis for a crank chamber and the machining axis for a fitting portion for the ratio detecting sensor are set parallel to each other.

A motor vehicle includes at least one steerable wheel, at least one drive wheel, a frame supporting the steerable and drive wheels, a power unit assembly mounted on the frame between the steerable and drive wheels, a speedometer supported on a front portion of the frame. The power unit assembly includes a crankcase, a gear transmission case connected to the crankcase, and a gear case attached to one side wall of the gear transmission case. A crankshaft is rotatably disposed in the crankcase. An output shaft operatively coupled to the crankshaft is rotatably disposed in the gear transmission case. A pair of bevel gears meshing with each other is rotatably mounted in the gear case and operatively coupled to the output shaft. A propeller shaft is connected between one of the bevel gears and the drive wheel. A speedometer cable has one end operatively coupled to the one bevel gear and the opposite end operatively coupled to the speedometer.

The present invention provides a compact tube clamping device 50 with a simple structure and used suitably for a hydraulic pressure tester for inspecting quality of an electric resistance welded tube. To achieve this object, a lifting/lowering base 52 including a tube support body 55 on itself is provided onto a fixed base 51 to be able to lift and lower. Clamp claws 56 are mounted in positions, between which the tube support body 55 of the lifting/lowering base 52 is sandwiched, to be able to turn. A claw drive body 58 for lifting and lowering independently of the lifting/lowering base 52 is provided in the lifting/lowering base 52. Opposite side portions of the claw drive body 58 are connected to the opposite clamp claws 56 by links 59 so as to turn the opposite clamp claws 56 in closing directions by lowering with respect to the lifting/lowering base 52. Both of a first drive mechanism 53 for driving the lifting/lowering base 52 for lifting and lowering and a second drive body 54 for driving the claw drive body 58 for lifting and lowering are provided to the fixed base 51. Because a lowering stroke of the claw drive body 58 necessary for closing operations of the clamp claws 56 is partially born by lifting of the lifting/lowering base 52 in transferring the tube, the lowering stroke of the claw drive body 58 for opening and closing the clamp claws 56 can be suppressed.
