摘要： PROBLEM TO BE SOLVED: To improve transmission performance when the temperature of lubricating oil is low.
SOLUTION: This transmission for a vehicle is provided with: a backward gear 12 fitted to a main shaft 10 as a rotating shaft so as to enable idling; a clutch gear 14 arranged relatively rotatably at only a predetermined angle with respect to the backward gear 12; a coupling sleeve 20 which has a spline engaged with the clutch gear 14 and formed at the inner periphery and is slidably fitted to the main shaft 10; and an elastic member 16 such as a compression coil spring for elastically energizing the relative rotation of the backward gear 12 and the clutch gear 14 toward the neutral position. When the coupling sleeve 20 is displaced to the clutch gear 14 direction to perform a gear shift from the stop state to a transmission gear, even if the backward gear 12 cannot be rotated, the coupling sleeve 20 rotates the clutch gear 14 withstanding the energizing force of the elastic member 16. By this engagement, transmission is completed.

摘要翻译：要解决的问题：为了提高润滑油的温度低时的传动性能。解决方案：这种车辆变速器具有：后轮12，该后齿轮12装配到作为旋转轴的主轴10上以便能够空转; 离合器齿轮14，其相对于后退齿轮12以相对可旋转的方式仅以预定角度布置; 连接套筒20，其具有与离合器齿轮14接合并形成在内周上的花键，并且可滑动地装配到主轴10; 以及诸如压缩螺旋弹簧的弹性构件16，用于将后齿轮12和离合器齿轮14的相对旋转弹性地向中性位置施力。当联轴器套筒20向离合器齿轮14方向移动以执行从停止状态到传动齿轮的换档时，即使后齿轮12不能旋转，联接套筒20也能够承受离合器齿轮14的转动，通过该接合，完成了传动。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To make "gear squealing" hard to be generated in gear shifting.
SOLUTION: A synchronizing device includes a synchronizer hub 12 integrated with a rotary shaft, a synchronizer sleeve slidably fitted to its outer periphery and a synchronizer ring pressed against a friction surface formed on a synchronized rotary member along with its axial displacement, wherein the synchronizer hub 12 includes a synchronizing hub 12A fixed to the outer periphery of the rotary shaft, a synchronized hub 12C installed for relative rotation to it by a predetermined angle and fitted with the synchronizer sleeve and an elastic member 12C biasing their relative rotation to a neutral position. Rotation fluctuation when the torsion of a driving force transmission system is returned by the completion of synchronization is absorbed by the elastic member 12C while the synchronizing hub 12A and the synchronized hub 12B are relatively rotated so that "gear squealing" is hardly caused.

摘要翻译：要解决的问题：在变速时难以产生“齿轮尖叫”。解决方案：同步装置包括与旋转轴一体化的同步器毂12，可滑动地装配到其外周的同步器套筒以及与其轴向位移一起压靠在同步旋转构件上形成的摩擦表面的同步器环，其中同步器毂12包括固定到旋转轴的外周的同步轮毂12A，安装成相对旋转预定角度并与其同步的套筒的同步轮毂12C，以及将其相对旋转偏压到中立位置当同步轮毂12A和同步轮毂12B相对旋转时，由弹性件12C吸收驱动力传递系统的扭转由同步完成而返回时的旋转波动，从而几乎不产生“齿轮尖叫”。版权所有（C）2009，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To enhance durability of a tapered roller bearing as a pilot bearing. SOLUTION: The bearing structure for the transmission is constituted so as to include an input shaft 24 inputted with rotation drive force; a main shaft 26 arranged coaxially to this; and a main counter shaft 28 arranged in parallel to these so as to gear-transmitting the rotation drive force from the input shaft 24 to the main shaft 26, and a front end of the main shaft 26 is relatively rotatably supported on an outer ring raceway surface 24A formed on a rear end of the input shaft 24 through the tapered roller bearing 46. A contact angle α of the outer ring raceway surface 24A is set to a predetermined angle taking into consideration that the input shaft 24 and the main shaft 26 are deflected by reaction force applied from the main counter shaft 28.
