ABSTRACT:
A rotary power transmission device including a hydraulic torque converter which transmits rotary power between coaxial power input and power output shafts, and a lock up clutch system which also transmits rotary power between the power input and power output shafts, wherein the lock up clutch system includes a rotary shock absorber including a disk shaped plate element and two ring shaped plate elements cooperating with an outer peripheral portion of the disk shaped plate element in an axially superposed manner so as to provide a rotary shock absorber, one of the two ring shaped plate elements being positioned between the other ring shaped plate element and the disk shaped plate element, the assembly of the two ring shaped plate elements and the outer peripheral portion of the disk shaped plate element being positioned in an annular space formed adjacent an outer peripheral portion of the turbine of the hydraulic torque converter, while the radially inner portion of the disk shaped plate element is rotationally connected to the power output shaft in parallel with the turbine, wherein more than two circumferentially elongated slot shaped apertures are formed in the middle ring shaped plate element, through each of which a pin rotatably supporting an annular bearing element is passed and mounted at its opposite ends to the other ring shaped plate element and the disk shaped plate element with the annular bearing element being engaged with either a radially inner or a radially outer arcuate edge of the slot shaped aperture.
