Support structure for drum support, has hollow hole formed linearly in symmetrical position to drum support and perpendicular to direction which passes relay oil path, bolt hole and axis core of drum support

摘要

A bolt hole (9e) is formed to a drum support (9) where a bolt is penetrated when supporting the drum support. A relay oil path (9d) is formed to drum support through which oil is supplied towards shaft tip of a connection element. A hollow hole (9c) is formed linearly in a symmetrical position to drum support and perpendicular to direction which passes relay oil path, bolt hole and axis core of drum support. The drum support is supported from the side of a control unit to an automatic transmission case.
