Abstract
There is provided a power-driven striking tool including: a casing; a tool holder rotatably supported inside the casing and having a front end to which a tool bit is attached; and an operating member fitted around the tool holder and exposed to the outside of the tool so as to be manually slidable in the axial directions of the tool holder and integrally rotatable with the tool holder. The operating member is biased rearward by a compression spring along the axis of the tool holder into contact with the casing. The tool further includes first teeth provided on the operating member where it comes into contact with the casing and second teeth provided on the casing where it comes into contact with the operating member. When the operating member is brought into contact with the casing, the first and second teeth engages each other to prevent the operating member and thus the tool holder from rotating relative to the casing.
