とする無段ロツク装置。 A deformable disk fixed to a driven shaft within a circular brake drum and having at least a portion of the long diameter portion is interposed between an inner circumferential surface of the brake drum and an outer circumferential surface sandwiching the long diameter portion of the deformable disk. At least a pair of left and right brake blocks, and a rotary body fixed to an operating lever and having a pawl inserted between the brake blocks, are built in, and between the deformable disk and the inner circumferential surface of the brake drum, The long diameter portion forms a space that gradually becomes wider in both directions, and the brake block is formed in a shape such that it is pressed against the inner peripheral surface of the brake drum and the outer peripheral surface of the deformable disk at the narrow portion of the space. and is always biased in the narrow direction of the space by the elastic member, and the rotating body is engaged with the disk with a required amount of play in the rotational direction, so that the rotation of the rotating body is The stepless lock is characterized in that the brake block is initially pressed in the wide direction of the space to release the pressure contact between the brake drum and the disk so that the disk can rotate relative to the brake block. Device.
