ABSTRACT:
A brake band device (1) for engagement and dis-engagement (braking and releasing) a cylindrical clutch drum of an automatic transmission includes a strap (12) formed of a belt-like member shaped into a substantially circular form, with a gap defined between ends of the strap (12). A lining (13) is fixed to the inner peripheral surface of the strap (12) and is engageable with the outer peripheral surface of the clutch drum. A pair of arc-shaped brackets (14) are fixed to each of ends of the strap (12), respectively. The strap is formed with a plurality of slightly deformed portions that extend slightly radially inwardly from other portions of the strap (12) thereby providing the strap (12) with a biasing force that allows for improved dis-engagement with the clutch drum.
