Claims

[Scope of Claim for Utility Model Registration] (1) Two roller supports that can be held while changing the facing distance are installed on a support fixed plate, and a bar-shaped material is placed on the upper end of the opposite side of the roller supports. In a test jig that is equipped with a rotatable fulcrum roller that supports the left and right parts, and in which a bar-shaped material placed across the fulcrum roller is pressed and bent by a vertically moving pusher, the upper end of the facing side is formed with a receiving recess into which each of the fulcrum rollers is fitted and supported, the fulcrum roller is rotatably supported on the upper part of the roller support base via a rotating arm, and both of the fulcrum rollers are supported by the holder. A jig for bending test of rod-shaped materials, characterized in that an evacuation space is secured to enable rotational displacement of the fulcrum rollers so that the distance between the two fulcrum rollers increases from the state in which they are fitted into the recessed part. Device. (2) A hook for holding the pressing and bending central part of the bar-shaped material is attached to the pushing metal fitting below the pushing surface for pushing the middle part of the bar-shaped material, and the hook can be vertically adjusted to push the bar-shaped material. 2. The jig device for bending test of a bar-shaped material according to claim 1, wherein the bar-shaped material can be lifted up by the hook after being bent.
