    摘要： To eliminate a play at connection portions in a valve characteristic varying mechanism (M) and to enhance the accuracy in control of valve operation characteristics.
    A valve characteristic varying mechanism (M) of a valve system (40) comprises a valve cam (54) pivotally supported on a camshaft (50) so as to put an engine valve (24) into opening and closing operations, a holder (60e) pivotally supported on the camshaft (50), a control mechanism (M3) driven by a drive mechanism to swing the holder (60e) about the camshaft (50), and a rocker arm (66e) which is pivotally supported on the holder (60e) and which is swung by a drive cam (52) rotated integrally with the camshaft (50) to swing a valve cam (54) about the camshaft (50). The control mechanism (M3) and the holder (60e) are pivotally connected to each other at their connection portions, and the valve characteristic varying mechanism (M) comprises a pressing spring (55) for normally pressing the holder side connection portion against the control mechanism side connection portion in the swinging direction.

    摘要： The invention provides
    a motor cooling structure for an electric vehicle which can efficiently cool a driving motor in a power unit case of the electric vehicle. According to the invention, a transmission case cover 59a having an air filter 41 is mounted on the left side surface of a transmission case 59 at a portion adjacent to a fan 54b, and a ventilation gap is defined between a rear portion of the transmission case cover 59a and the transmission case 59. The transmission case cover 59a is formed with a cooling air inlet 59b facing the above ventilation gap. When the fan 54b is rotated in synchronism with a crankshaft 22, an outside cooling air is introduced from the cooling air inlet 59b into the transmission case cover 59a and is then passed through the air filter 41 to enter the transmission case 59, thereby forcibly cooling a CVT 23. Thereafter, a part of the cooling air introduced into the transmission case 59 is discharged from a central air outlet 42 to the outside of the transmission case 59, and the remaining cooling air is drawn to the driven portion of the CVT 23.
