Claims

[Claims for Utility Model Registration] 1. A handle pin A is attached to the side frame supported by the legs at a position _l2 from the center of the stay A fixed between the frames in parallel with the attached roller and drive roller. A bar handle is installed with the bar handle as a fulcrum, and in the auxiliary roller that moves the drive roller up and down by the bar handle, there is a two-stage lift rod between the bar handle and a lift rod that grips the drive roller shaft that rotatably supports the drive roller. A lever is formed at point a of the bar handle so that when the bar handle pushes up the drive roller with the workpiece to be cut placed on the drive roller, the biasing force of the handle spring is applied in a direction that reduces the downward load on the bar handle. One end of the handle spring is suspended from the fixed handle pin C, and the other end is suspended from the spring supporter part of the stay B fixed to the lower part between the frames, and when the bar handle goes up, the handle spring is attached in the direction to reduce this. An auxiliary roller for a horizontal band saw, which is configured to apply force and can be operated with a substantially constant load during operation. 2. When moving the bar handle up and down, holes are formed in the leg at the upper and lower limit positions of the bar handle, and the leg is slidably inserted into the hole on the fulcrum side of the bar handle and secured by a roll pin or the like. The auxiliary roller for a horizontal band saw according to claim 1, which can be fixed by inserting a movable part of a provided bar handle.
