PROBLEM TO BE SOLVED: To provide a pruning ruler by which the finishing by pruning of trees can be carried out linearly.SOLUTION: The pruning ruler comprises a body A1, a body B2, a body C3, a bubble level 7, comb-shaped upper pins 4 and comb-shaped lower pins 5. The pruning ruler is positioned horizontally or with a slope by using the bubble level 7 as an index by allowing the comb-shaped upper pins 4 and the comb-shaped lower pins 5 to be inserted directly into arbitrary positions of the objective tree to provide the flat pruning ruler composed of the body A1, the body B2, the body C3, and the comb-shaped upper pins 4 or the comb-shaped lower pins 5.COPYRIGHT: (C)2012,JPO&INPIT【課題】樹木の刈込仕上げを直線的に行える刈込定規を提供する。【解決手段】本体A1、本体B2、本体C3を気泡管7を目安に水平または勾配をつけ、クシ状上段4及びクシ状下段5を直接対象樹木の任意の位置に差し込むことにより本体A1、本体B2、本体C3及びクシ状上段4またはクシ状下段5が平面的な刈込定規になる。【選択図】図1
