ABSTRACT:
Thrust force generated by a hydraulic actuator is absorbed in a attachment device for a four speed automatic transmission mechanism. When hydraulic pressure is applied to the hydraulic actuator to engage a third and a fourth clutches, pressing force from a piston works on a strut member situated between the third and fourth clutches as a compression force, while a force working on a drum member as a tension force, so that these forces are counterbalanced and absorbed in the attachment device. Consequently, one directional move of the attachment device is supported by a little force such as contacting a snap ring and a thrust washer to a clutch drum, on the other hand, another move of the attachment device is supported by a little force such as connecting the drum member and a big ring gear by a snap ring.
