機構。 In a drum brake equipped with a pair of brake shoes, an operating lever whose base end is pivotally supported by one brake shoe is connected to a wire at its tip, and the tension of the wire causes the tip to move to the other brake shoe. a strut that is rotatably provided so as to approach the brake shoe, one end of which engages with an abutting portion provided at an intermediate portion of the operating lever, and the other end of which engages with the other brake shoe; The variable lever ratio parking brake mechanism is characterized in that a guide portion is formed in the contact portion to slide and guide one end of the strut toward the base end of the operating lever when the operating lever rotates. .
