PROBLEM TO BE SOLVED: To prevent the generation of vibration due to surging occurring to a hand type grinding device. SOLUTION: A hand type grinding device is formed in such a manner that a drive shaft 4 is supported at the inside of the hand type grinding device body 1 by means of a bearing and one end of a connecting rod 7 is pivotally supported on the outer periphery of the drive shaft 4 through an eccentric crank body 5; and the other end of the connecting rod 7 is connected to the chuck part 8 of a tool arranged at the tip part of the grinding device body 1. By forming the connecting rod 7 of a resilient substance bent in one-way, follow-up to deformation of the connecting rod 7 is improved and the generation of vibration due to surging is prevented from occurring. |
