バンド式ブレーキのレバー装置。 In a band-type brake lever device in which one end of the rod is connected by a connecting pin to a connecting lever that swings at a fixed angle as the operating lever swings, the sliding trajectory of the connecting pin is changed so that the lever ratio changes. A fixed guide plate with an arc-shaped guide elongated hole that defines the length is attached to the frame, and a long hole for sliding a connecting pin is provided in the longitudinal direction of the connecting lever, and the guide elongated hole of the fixed guide plate and the length of the connecting lever are provided. The connecting pin fitted into the hole is located at one end of both elongated holes when the band type brake is in the brake release state, and as the connecting lever swings toward the braking side, it is located at the other end of both elongated holes. A lever device for a band type brake, characterized in that it is configured to slide toward the front side.
