An engine for vehicle includes an oil hydraulic automatic transmission for changing the change gear ratio by control of an oil pressure. The oil pressure control unit of the transmission includes a plurality of control valves for controlling the oil pressure, and is mounted to an upper portion of a crankcase. A power transmission shaft interlockedly connected to a counter shaft and having an axis parallel to the counter shaft is disposed on the lower rear side of the counter shaft, and a drive bevel gear on the power transmission shaft and a driven bevel gear are meshed with each other on the rear side of the axis of the power transmission shaft. The resulting configuration eliminates the need for a special measure to protect the oil pressure control unit, and prevents interference of the driven bevel gear with the gear speed change mechanism.

A starting clutch includes a clutch inner that is secured to and supported by a drive plate boss fitted to a crankshaft near the end thereof. A one-way clutch is fitted to the outer periphery of the cylindrical portion extending inwardly. A clutch outer forms an annular portion that covers the outer periphery of the drive plate. A hollow disk portion covers the inner surface and is rotatably supported by the crankshaft. The one-way clutch is clamped by the inner peripheral edge of the hollow disk portion of the clutch outer from the outer peripheral side in cooperation with the cylindrical portion of the drive plate boss, and the inner peripheral edge of the hollow disk portion of the clutch outer abuts against a flange portion of the drive plate boss extending along the inner surface of the drive plate in the centrifugal direction thereof.

A water-cooled internal combustion engine configured so as to facilitate the change of the cooling system, thereby reducing costs. The crankcase of the water-cooled internal combustion engine is adapted to journal a crankshaft. The crankcase is covered by a crankcase cover from the axial outside. The crankcase is connected to the crankcase cover through an annular shaped spacer, and at least part of a water pump is formed integrally with the spacer.

An outer circumference of a shift drum of a vehicle transmission is provided with at least one particular lead groove among multiple lead grooves which continuously extends beyond one circle of the shift drum. Two ends of the particular lead groove are arranged so as to be out of alignment with each other in the axial direction of the shift drum. A common shift position adapted to establish gear trains with two shift stages different from each other is set at one position corresponding to the two ends of the particular lead groove along the circumferential direction of the shift drum. The resulting configuration prevents an increase in the diameter of a shift drum and eliminates the significant change of the shape of a lead groove, even as the number of shift positions set on the shift drum is increased.

A power unit provided with a dry sump type lubricating device includes a power unit case that is covered in part by a power unit case cover and is divided into a front unit case and a rear unit case. The power unit also includes a crankshaft rotatably supported by a crank chamber that is formed by the power unit case and a shift shaft rotatably supported by a transmission chamber that is provided adjacent to the crank chamber. The power unit also includes an oil tank disposed on the crank chamber side of an anteroposterior outside surface of the power unit case cover and a hydraulic control device for controlling a shift clutch, disposed on the transmission chamber side of the anteroposterior outside surface of the power unit case cover.

A monodisperse spherical, ellipsoidal or plate-like vaterite calcium carbonate almost free from secondary aggregation is disclosed. The vaterite type calcium carbonate is prepared by the steps of adding 5-20 times mol equivalent of water with respect to unslaked lime to a methanol suspension of 0.5-12 weight % of unslaked lime and/or slaked lime (in case of slaked, conversion is to be made into unslaked lime of the same mol) to prepare of a mixture of methanol, unslaked lime and/or slaked lime and water, letting carbon dioxide gas through said mixture, adjusting the temperature in the carbonation reaction systemto not less than 30.degree. C. before arrival of conductivity within carbonation reaction system at the maximal point on conductivity variation curve in the carbonation reaction system and adjusting the time from start of carbonation reaction to the point where the conductivity is 100.mu. S/cm to be less than 1,000 minutes. A method for growing or controlling in shape the vaterite calcium carbonate used as matrix is also disclosed.
