Claims

[Claims for Utility Model Registration] A belt tension adjustment device for adjusting the tension of a belt that transmits power from a driving device to a driven device to an appropriate value by moving the driven device, the belt tension adjusting device comprising: A bracket that is connected to the drive device, a bolt that fixes the driven device to the bracket by tightening a nut, a rack member, a resilient member that applies appropriate tension to the belt, and a bolt that fixes the driven device to the bracket by tightening a nut; and a stopper member that is fixed and restricts the movement of the rack member. The bracket includes a main body and a flange protruding from the main body at a substantially right angle, and the main body includes the driven device. A long hole extending substantially parallel to the direction of movement of the bolt is bored, and the bolt has, in order from its end, a head for engaging a tool, a pinion part that can engage with the rack member, and a pinion part that can be engaged with the rack member. The rack member is arranged substantially parallel to the elongated hole along the main body of the bracket, and the elastic member is arranged between the rack member and the flange of the bracket. The threaded portion of the bolt is loosely fitted into the elongated hole, the screw portion of the bolt is engaged with the rack member, and the elastic member is arranged between the rack member and the rack member. 1. A belt tension adjusting device, wherein the stopper member is pressed against a pinion portion, and the stopper member only allows the rack member to move in the direction of expansion and contraction of the elastic member.
