    • An angular velocity sensor which suppresses the generation of noise in a detector piezo-electric element due to vibration of a vibrator caused by expansion and contraction of a driver piezo-electric element. A driver piezo-electric element 6 is adhered to an upper part on the left-side surface of a first square pole 3 of a vibrator 1 and a driver piezo-electric element 7 is adhered to an upper part on the right-side surface of a second square pole 4. Further, a detector piezo-electric element 8 is adhered to a lower part on the front surface of the first square pole 3 of the vibrator 1 and a detector piezo-electric element 9 is adhered to a lower part on the front surface of the second square pole 4. Here, the driver piezo-electric elements 6, 7 and the detector piezo-electric elements 8, 9 are disposed so as to be deviated so that they will not overlap in the axial direction of the square poles.

    • In a chamber R1 which accommodates a transmission device comprising a drive pulley 8, a driven pulley 9 and a belt 10, a cover 51 is provided to cover the lower peripheral portion of the drive pulley 8 along the periphery. The drive pulley is positioned below the driven pulley, and raised portions 52 which are used for the detection of the rotational speed of the drive pulley are provided on the periphery of the drive pulley. The end surface 51bs of the cover facing the inner wall 54 of the pulley chamber is positioned away from the inner wall with a clearance V therebetween. In a vehicular transmission which is constructed in this arrangement, the amount of lubrication oil that flows near to the periphery of the pulley which is positioned lower is comparatively small. Thus, this arrangement restricts agitation of the lubrication oil, which may be caused by the raised portions of the rotating pulley. Therefore, loss in the rotation of the pulley and oxidation and degradation of the lubrication oil are effectively prevented.
    • 在容纳包括驱动带轮8,从动带轮9和带10的传动装置的室R1中,设置有盖51,以沿着周边覆盖驱动带轮8的下周边部分。 驱动滑轮位于从动皮带轮的下方,并且用于检测驱动皮带轮的转速的凸起部分52设置在驱动皮带轮的周边上。 面向皮带轮室的内壁54的盖的端面51bs定位成远离内壁,其间具有间隙V. 在这种结构中构成的车辆用传动装置中,位于下侧的带轮周边附近流动的润滑油量相对较小。 因此,这种布置限制了可能由旋转滑轮的凸起部分引起的润滑油的搅动。 因此,有效地防止了滑轮的旋转损失和润滑油的氧化和劣化。

    • In a power transmission system in a vehicle including a continuously variable gear path and a multi-stage gear path, a difference between gear ratios at the start of forward travel and at the start of backward travel is minimized, while using a single-pinion type planetary gear mechanism. The continuously variable gear path includes a forward/backward travel switching mechanism comprising a single-pinion type planetary gear mechanism, and a belt-type continuously variable transmission. A multi-stage gear path comprising gears is set at a gear ratio closer to a LOW side from that of the belt-type continuously variable transmission. Thus, when the forward traveling and the backward traveling are switched over from one to another, it is unnecessary to suddenly change the gear ratio of the belt-type continuously variable transmission, which can contribute to an improvement in durability of belt-type continuously variable transmission.
    • 在包括无级变速档和多级齿轮路的车辆的动力传递系统中,在向前行驶开始时和后行驶开始时的齿轮比之间的差最小化,同时使用单小齿轮型 行星齿轮机构。 连续可变齿轮路径包括包括单小齿轮型行星齿轮机构和带式无级变速器的前进/后退行驶切换机构。 包括齿轮的多级齿轮路径被设定为比带式无级变速器更接近LOW侧的齿轮比。 因此,当向前行驶和后退行驶从一个切换到另一个时,不需要突然改变带式无级变速器的齿轮比,这有助于带式连续变量的耐久性的提高 传输。
