PROBLEM TO BE SOLVED: To provide a fixing claw and a fixing claw holding member that can till up immediately before and immediately below a drive case comprising a transmission for driving an axle and a tilling shaft and a support for holding a gear case and a tilling shaft, in a tilling rotary comprising multiple tilling claws mounted to the axle and the tilling shaft.SOLUTION: A rotary-type tiller is mounted with a tilling rotary with multiple tilling claws attached in a tilling shaft. The rotary-type tiller comprises: a fixing claw holding member 5 fixed to a drive case 1 having an axle and the tilling shaft in the inside of a trajectory 8 of a tilling claw tip multiple tilling claws 3 being the closest to the drive case 1 and fixed to the tilling shaft 2M bent toward the drive case 1 and a fixing claw 6 having a portion 6h of the fixing claw 6 in the side spaced-apart from the drive case 1 more than a trajectory cross section 10 of the tilling claw tip, and a portion 6l of other fixing claws 6 having a shape crossing between the trajectory cross section 10 of the tilling claw tip of both sides of the drive case and the trajectory cross section 11 of the tilling claw tip. The fixing claw holding member 5 is mounted and disposed in a position capable of being held in order to obtain conditions for mounting the fixing claw.SELECTED DRAWING: Figure 4COPYRIGHT: (C)2016,JPO&INPIT【課題】車軸、耕耘軸に取付けた複数の耕耘爪からなる耕耘ロータリにおいて、車軸、耕耘軸を駆動するミッション、及びチェーンケース、耕耘軸を保持するサポートを含むドライブケースの直前および直下を耕起出来る固定爪と固定爪保持部材を提供する。【解決手段】耕耘軸に複数の耕耘爪を取付けた耕耘ロータリを装着したロータリ式耕耘機において、耕耘爪先端の軌跡8の内側で、車軸、耕耘軸を持つドライブケース1に固定した固定爪保持部材5と、ドライブケース1に最も近く、ドライブケース1に向けて曲がった耕耘軸2Mに固定された複数の耕耘爪3と、その耕耘爪先端の軌跡断面10よりドライブケース1から離れた側に固定爪6の一部6hがあり、その他の固定爪6の一部6lがドライブケース両側の耕耘爪先端の軌跡断面10と耕耘爪先端の軌跡断面11の間を横切る形状を有する固定爪6で構成し、固定爪を装着する条件を得るため保持出来る位置に固定爪保持部材5を装着配置する。【選択図】図4
