摘要： A hydraulic power transmission includes a pump impeller, a turbine impeller, a cover member, a lock-up clutch, an output member, a plurality of primary springs, a plurality of secondary springs, an intermediate member, a first dynamic vibration absorber, and a second dynamic vibration absorber. The intermediate member holds the output member and connects the primary springs and the secondary springs. The first dynamic vibration absorber is attached to the intermediate member and has a first frequency. The first dynamic vibration absorber includes a first mass body and a first damper member. The second dynamic vibration absorber is attached to the intermediate member and has a second frequency different from the first frequency. The second dynamic vibration absorber includes a second mass body and a second damper member.

摘要： A stator of a torque converter is divided into a first stator on an upstream side and a second stator on a downstream side, and the first and second stators are supported on a fixed part via first and second one-way clutches, respectively. Since, with regard to a blade of the first stator, when viewed in the axis direction, the blade tip part is inclined relative to the blade base part in the disengagement direction of the first one-way clutch, it is possible to ensure the blade area without increasing the dimension in the radial direction and the dimension in the axis direction of the blade of the first stator, and it is possible, by smoothly guiding oil along the blade of the first stator to thus suppress the occurrence of a vortex, to reduce energy loss in a low speed ratio region where the vortex easily occurs.

摘要翻译：变矩器的定子分为上游侧的第一定子和下游侧的第二定子，第一和第二定子分别经由第一和第二单向离合器支撑在固定部上。由于关于第一定子的叶片，当从轴线方向观察时，叶片前端部在第一单向离合器的分离方向上相对于叶片基部倾斜，因此能够确保叶片在不增加径向尺寸和第一定子的叶片的轴向尺寸的情况下，可以通过沿着第一定子的叶片平滑地引导油从而抑制涡流的发生，降低涡流容易发生的低速区域的能量损失。
