A tensioning pulley device for an elevator speed governor rope, comprising: a tensioning pulley suspended by a speed governor rope; a rotating member rotated by the displacement of the tensioning pulley in the up-down direction: a restricting member, a rotating member Rotation in the direction of displacing the tension pulley upward, the interval between the restricting member and the rotating member becomes smaller; a wedge inserted between the rotating member and the restricting member; The pressing force is applied in a direction in which the distance between the rotating member and the restricting member is widened. A support member is provided in the merging channel. The rotating member and the restricting member are provided on the support member. The wedge is provided with a first abutting surface abutting against the rotating member, and a second abutting surface inclined with respect to the first abutting surface and abutting with the restricting member. A wedge is pressed between the rotating part and the restricting part, thereby preventing the tension pulley from shifting upwards.
