摘要： PROBLEM TO BE SOLVED: To enhance the workability and handleability of a disc grinder or the like by downsizing a power transmission part because there is a problem that, in a disc grinder where the rotation axis of a spindle intersects the motor axis of a power motor, a bevel gear is used for converting a power transmission direction while decelerating rotative power, however, the diameter of the bevel gear is relatively large, thereby the size of a gear head is increased, and workability is degraded.SOLUTION: A power transmission part 3 is downsized by using an outer rotor type electric motor 10 capable of outputting low-speed rotation and high torque as a drive source, and interposing universal joints 12, 13 instead of conventional bevel gears between its output shaft 10c and a spindle 14.
摘要翻译：要解决的问题：为了通过减小动力传递部件来提高盘式磨碎机等的可操作性和可操作性，因为存在以下问题：在主轴的旋转轴与电动机轴的轴线相交的盘式磨碎机中动力马达，伞齿轮用于在使转动力减速的同时转换动力传递方向，但是锥齿轮的直径相对较大，因此齿轮头的尺寸增大，加工性下降。解决方案：通过使用能够输出低速旋转和高扭矩作为驱动源的外转子型电动机10来减小动力传递部3，并且在其间插入万向接头12,13而不是传统的锥齿轮输出轴10c和主轴14.版权所有（C）2013，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a disk-shaped tool whose attachment/detachment to/from a rotating shaft is made easy, and to provide an electric tool equipped with the same.SOLUTION: There is provided a disk-shaped tool equipped with, at its center, a screw hole 30 for threadably engaging it with a rotating shaft 63. On a circumference with the screw hole as its center, a plurality of through-holes 40 are formed in a circumferential direction at given intervals. Intervals C between at least some of the through-holes are made so as to enable a pair of engagement portions 72, 72, provided in a tool 70 for performing an attaching/detaching operation to/from the rotating shaft, to be engageable with the through-holes. Further, the through-holes 40 are also used as dust collection holes for collecting powder dusts generated in use.

摘要：【課題】電動工具の外装部分に環状の引掛部を設け、引掛部の貫通孔にカラビナやロープ等を通す。カラビナやロープ等を手すりや足場に設けられたフック等に引き掛けることで、電動工具を吊り下げることができる。引掛部には電動工具を吊り下げる時に電動工具の重量分の負荷が加わる。変形やクラックの生じた引掛部は吊り下げ時の負荷によって破損する恐れがある。負荷に対抗できるように引掛部を大きく設けると、使用者の腕や作業面等に当たって使用感を損ねてしまう。引掛部の変形や破損を防ぐには、作業の妨げにならない形状を保ちながら、強度や靭性を高めることが求められる。【解決手段】外装ケース40と一体に設けられた環状の引掛部41の内部に、環状に沿った金属製のワイヤー42が設けられる。引掛部41がワイヤー42で補強されることで、引掛部41の変形や破損に伴う電動工具の落下等を防ぐことができる。【選択図】図3
