CUTTING RULER

To provide a cutting ruler which can easily set a right angle between a guide plate and a guide part.SOLUTION: The cutting ruler includes a guide plate 4 provided in a direction orthogonal to a guide surface 2, a screw body 63 provided on one end side 3R in a lengthwise direction of a guide rod 3, a slide groove 6 which is provided in a lengthwise direction of the guide plate 4 and guides the screw body 63, and a brace rod 9 which rotatably connects one end side 9M to the guide plate 4, and connects the other side to the other end side of the guide rod 3. Since an orthogonal guide groove 71 for guiding the screw body 63 during rotation of the brace rod 9, and maintaining the guide surface 2 in a state of being orthogonal to the guide plate 4 is provided, in order to make the guide surface 2 and the guide plate 4 orthogonal to each other, an orthogonal state can be obtained not by fixing a fastening screw 5 at only one point but by fixing the fastening screw 5 in the orthogonal guide groove 71.SELECTED DRAWING: Figure 1 【課題】ガイド板と案内部との直角の設定を容易に行うことができる切断用定規を提供する。【解決手段】案内面２と直交方向に設けられるガイド板４と、案内杆３の長さ方向一端側３Ｒに設けられるネジ本体６３と、ガイド板４の長さ方向に設けられネジ本体６３を案内するスライド溝６と、ガイド板４に一端側９Ｍを回転可能に連結すると共に、他端側を案内杆３の他端側に連結した筋交い杆９とを備える。筋交い杆９の回動時にネジ本体６３を案内して案内面２をガイド板４と直交状態に保持する直交案内溝７１を設けたから、案内面２とガイド板４とを直交状態にするために締付ネジ５を１点のみで固定するのではなく、直交案内溝７１内において締付ネジ５を固定することにより直交状態を得ることができる。【選択図】図１
