摘要： A variable valve apparatus of an internal combustion engine includes a cam shaft, a drive cam formed integrally with the cam shaft, and a rocker arm mechanism for transmitting an opening/closing force from an operating end portion thereof to an intake or an exhaust valve by receiving the opening/closing force by a drive cam opposed roller brought into contact with the drive cam. For displacing a lift time period, in which the drive cam opposed roller receives the opening/closing force, frontward/rearward in a direction of rotating the drive cam, an up section of a cam lift face of the drive cam is formed to be longer than a down section thereof such that a change region of a lift valve closing time point of the lift time period becomes larger than a change region of a lift valve opening time point thereof.

摘要： A motor of this invention is provided with a sleeve-type bearing impregnated with oil for supporting a rotor assembly including a shaft and a rotor member. A lower face of the rotor is provided with at least two peripheral wall portions, an inner peripheral wall portion and an outer peripheral wall portion, which surround the shaft with a gap therebetween in a radial direction. The peripheral wall portions are accommodated in an annular recessed portion so as to surround an open space over a sleeve constituted the sleeve-type bearing and has a lower top of the most inner part. The lower end of the inner peripheral wall portion is located lower than the lower end of the outer peripheral wall portion, and the lower end of the outer peripheral wall portion is located lower than the lower top of the annular recessed portion.

摘要： A variable valve train apparatus operable in a low-speed mode in which a low-speed rocker arm is rocked by a low-speed cam through a roller or a slipper to thereby open or close an intake valve, and in a high-speed mode in which a high-speed rocker arm is rocked by a high-speed cam through a roller or a slipper and a changeover mechanism part on the side of the low-speed rocker arm is pressed by a changeover mechanism part on the side of the high speed rocker arm together with which the low-speed rocker arm is rocked to open or close the intake valve. The axis of the changeover mechanism part is positioned at the middle of the width of the roller or slipper in the axial direction of the rocker shaft to prevent inclination of the high-speed rocker arm.
