ンパクトになる。(Effects of the Invention) As described above, according to the present invention, in the automatic transmission in which the torque converter case 3 and the transmission case 2 are integrally formed as the housing 1, a plurality of boss portions 24 are formed on the outer peripheral portion of the partition wall 23. The boss portion 24 is provided with a locking hole 25 penetrating in the radial direction for pin engagement, and a screw hole 30 penetrating in the radial direction is formed in the housing portion corresponding to the locking hole 25. The mounting screw 33 having the portion 33a is attached to the screw hole 3 from the outside in the radial direction.
The partition wall 23 is positioned in the rotational direction and the axial direction by screwing into 0 and engaging the small-diameter pin portion 33a, and the partition wall outer periphery and the housing are fitted to each other, and between the partition wall inner periphery and the rotating member, respectively. Since the seal member 40 is arranged: (1) Compared with the conventional mounting screw structure that is screwed in the axial direction,
The outer diameter of the housing 1 becomes small, and the housing itself becomes compact.
（２）ハウジング１の半径方向外方から取付ねじ３３を
脱着することにより、隔壁２３を脱着できるので、従来

すい。(2) Since the partition wall 23 can be attached / detached by attaching / detaching the mounting screw 33 from the outer side in the radial direction of the housing 1, compared with the conventional case where the mounting screw is inserted into the torque converter case through the lateral opening. It is easy to disassemble and assemble the partition wall.
（３）ハウジング１の半径方向外方から取付けねじ３３

性が向上する。(4) Radial locking holes 25 for pin engagement are provided in the partition wall 23, and the tip pin portion 33a of the mounting screw 33 with the tip small diameter pin portion 33a screwed into the screw hole 30 on the housing side.
Since the partition wall 23 is positioned in the rotation direction and the axial direction by engaging with the locking hole 25, even when the housing or the partition wall 23 is distorted due to heat during operation, the partition wall 23 is directly screw-fastened. Compared with, the pin engagement has a relief, so that a certain amount of force can be relieved, thereby improving durability.
（５）先端小径ピン部３３ａと係止孔２５による係合構
造を利用しているので、ねじでリジットに締結する場合
に比べ、隔壁にねじ用ボス長さ等が不要となり、一層半
径方向のコンパクト化が達成できる。(5) Since the engaging structure of the small tip pin portion 33a and the locking hole 25 is used, the partition wall does not need a screw boss length, etc., as compared with the case where the rigid portion is fastened with a screw. Compact size can be achieved.
（６）隔壁２３の係止孔２５は、ねじ孔ではないので、
たとえば、分解時には、この係止孔２５にかぎ状のもの
を係合して隔壁２３を軸方向に引き出すことができ、便
利である。(6) Since the locking hole 25 of the partition wall 23 is not a screw hole,
For example, at the time of disassembly, a hook-shaped member can be engaged with the locking hole 25 to pull out the partition wall 23 in the axial direction, which is convenient.
特に、外周にＯリングが装着してあるような場合には、
大きな引き抜き力が必要となるが、上記にように係止孔
２５を利用することにより、簡単に取り出すことができ
る。Especially when an O-ring is attached to the outer circumference,
Although a large pulling force is required, it can be easily taken out by using the locking hole 25 as described above.
