Abstract: The variable valve actuating device (20) comprises a valve lifter (24) interposed between a swing end of a rocker arm 22 and a stem end of an engine valve (17), and a switch pin (53) slidably received in the valve lifter (24) so as to selectively abut the end surface of the valve stem as the valve lifter is actuated by a cam (21a). The swing end of the rocker arm abuts an upper end of a projection (55) projecting from the upper end of the valve lifter via an engagement feature (26b, 55a) that prevents a rotational movement of the valve lifter relative to the swing end around the axial line of the valve stem.

Abstract: For reduction in size and weight, friction materials aiming at a high coefficient of kinetic friction have been developed. However, friction materials with a high coefficient of kinetic friction may cause sticking to a sliding partner material and deteriorated feeling in operation in particular in the initial running-in period during the initial stage of use. Therefore, the use of friction materials with a high coefficient of kinetic friction has been restricted. Since such sticking to the sliding partner material is less likely to occur after experiencing an initial running-in period, developed was a friction material in a form that is effective in prevention of sticking during the initial running-in period.

Abstract: A bearing assembling apparatus is capable of assembling a bearing at a high speed and preventing an excessive unbalanced load from being applied to an outer ring and an inserting means at a time of inserting a rolling element. The bearing assembling apparatus has a compact size, with an inserting means arranged within an outer ring, and a feeding means guiding a needle to the inserting means. The feeding means is provided with two guide paths which can hold needles in line. The inserting means includes a receiving portion receiving the needles, guide grooves directed toward an installation space in the outer ring, and a cam member having two cam surfaces. The cam surfaces press the needles in the receiving portion toward the installation space. The guide grooves and the cam surfaces are provided at positions such that the last two needles can be simultaneously inserted into the installation space.

Abstract: A lightweight and high-strength valve lifter is excellent in wear resistance and sliding properties. The valve lifter is made of a titanium alloy having a hardened layer on the top surface thereof, on which a cam is caused to slide. The hardened layer is composed of an ?-case and an oxygen diffusion layer under the ?-case. The ?-case 22 is formed in a thickness of not less than 3 ?m and not more than 15 ?m. The oxygen diffusion layer has a thickness of not less than 10 ?m. The hardened layer on the top surface of the valve lifter is formed by oxidation treatment in a furnace at a temperature of not less than 600° C. An outermost oxide layer 21 formed on the ?-case as a result of the oxidation treatment is removed.
