PURPOSE:To improve a removal and an assembly characteristic of an internally fitting member, by providing a tapping hole in the internally fitting member mounted to the internal surface of a speed changer case. CONSTITUTION:An automatic speed changer is constituted by a fluid type torque converter, transmission and an oil hydraulic control device. A speed changer case of the automatic speed changer tightens by many bolts a torque converter housing containing the torque converter, transmission case integrally forming each chamber containing an overdrive and an underdrive speed change gear and an extension housing. An internally fitting member 2, providing a tapping hole 3 penetrating a partition 2B dividing an overdrive mechanism chamber from an underdrive mechanism chamber while having an internal thread 3A, is removed and assembled by screwing the external thread of a jig to said tapping hole 3. |
