A hard disk drive includes a base having a bottom plate. A magnetic body is embedded in the bottom plate. The magnetic body is allowed to serve as a magnetic shield in the hard disk drive. The magnetic body is allowed to have a sufficient thickness without requiring an additional space outside the base, since the magnetic body is embedded in the base. The magnetic field directed outside the base can reliably be absorbed at the magnetic body. The magnetic body may be received in a depression defined in the bottom plate. The depression may be formed based on a reduction in the thickness of the bottom plate.

An air-intake duct, which is disposed between an air outlet of an air cleaner box constituting an air cleaner and an air inlet of a throttle body constituting a throttle device, is configured to guide air cleaned by the air cleaner to the throttle device. The air-intake duct includes a tubular coupling member including an upstream coupling portion coupled in an air tight manner to the air outlet of the air cleaner box and a downstream coupling portion air-tightly coupled to the air inlet of the throttle body, the coupling member being entirely formed of an elastic rubber material. The air-intake duct also includes an air guide member including a first air inlet configured to take in air therethrough from inside the air cleaner box, a first air outlet configured to discharge the air therethrough toward the throttle body, and a fitting portion fitted to the coupling member.

A gear part of the present invention includes a lubrication coating formed on a surface of the gear part, the lubrication coating containing an organic phosphorous compound. In the gear part, when a tooth surface of the gear part is engaged with a tooth surface of a counter member, the organic phosphorous compound is transferred to the tooth surface of the counter member and another lubrication coating containing the organic phosphorous compound is formed on the tooth surface of the counter member. As a result, the lubrication coating can be held on the surface of the gear part for long periods.

There is provided a lubricating device for a motorcycle combustion engine, which allows the motorcycle to exhibit a desired banking angle and also to have a lower center of gravity. The lubricating device is designed to supply a lubricant oil to an in-line multicylinder combustion engine (E) mounted on a motorcycle frame structure (FR) and having a crankcase (CR) and includes a main gallery (21) formed in a lower portion of the crankcase (CR) and journal oiling passages (25) branched off from the main gallery (21) for supplying the lubricant oil towards crank journals (23b) of a crankshaft (23) of the engine. The main gallery (21) has opposite end portions (21a, 21a) inclined to extend outwardly upwardly.

There is provided a multicylinder four-cycle combustion engine, in which a communication hole is formed, to allow gases to flow smoothly form one cylinder to another so that the pumping loss occurring within the cylinders can be reduced. The combustion engine (E) includes an engine casing (EC) having defined therein a plurality of cylinders (2A to 2D), each having a cylinder bore (20A to 20D), and a crank chamber (30A to 30D) below the respective cylinder bore. A partition wall (21) separating the neighbor cylinder bores (20A, 20B; 20C, 20D) of the cylinders (2A to 2D) and the crank chambers (30A to 30D) from each other is formed with a communication hole (4). An open edge portion (4aa) of the uppermost edge (4a) thereof, which opens into the cylinder bore (20A to 20D) has a circumferentially intermediate major portion extending in a direction substantially perpendicular to the cylinder longitudinal axis (CH).
