Abstract
A multi-disk brake for an automatic transmission having a plurality of annular outer lamellae having a larger diameter and a plurality of annular inner lamellae having a smaller diameter, the outer and inner lamellae being alternately arranged and interleaved in the axial direction. The outer lamellae are splined to the transmission case while the inner lamellae are rotatably supported on the case. The multi-disk brake has an engagement/disengagement mechanism capable of pressing the outer and inner lamellae so as to bring the same into frictional engagement and capable of disengaging and releasing the outer and inner lamellae from each other. A support member is inserted into the lowermost portion of an annular gap formed between outer the peripheral surfaces of the outer lamellae and the inner peripheral surface of the case, the support member supporting the outer lamellae biases them upward, thereby preventing any rotational drag motion of the outer lamellae.
