インパクト回転工具
Document Type and Number:
Japanese Patent JP6726892
Kind Code:
B2
Abstract:
A holding pin protrudes from a first opening of a through hole, enters a hole formed in a tip tool, and holds the tip tool. A spring member energizes the holding pin. A bush is press-fitted in the through hole and supports the spring member at a first end portion thereof. An inner diameter of a second opening of the through hole is formed larger than an outer diameter of the bush. As a result of this, a second end portion of the bush is arranged to avoid contact with the second opening of the through hole.
