Abstract
A adjustment lever (,) has dual-functions characterized in that when an actuating force to a brake shoe (,) to move outward reaches predetermined magnitude, a device (,) prevents over-adjustment of shoe-to-drum clearances disables a device (,) to restrict return positions of brake shoes inhibiting the brake shoes movement in the direction to separate each other and when a brake temperature rises certain degree, a device (,) to prevent over-adjustment of brake shoe-to-drum clearances disables the device (,) to restrict return position inhibiting the brake shoe movement as well. The inventive design secures the function of over-adjustment prevention of the shoe-to-drum clearances and to downsize and to lighten a drum brake device without sacrificing its operation
