摘要： PROBLEM TO BE SOLVED: To provide a compact hammer having a short total length, and reduced in the number of part items.
SOLUTION: A tool holder 50 is detachably arranged in a tip part of a tool body, and a tip tool 35 is detachably arranged in the tool holder. A tool sleeve 51 is attached-detached by a sphere 54, a first fixing member 55, and a first operation sleeve 56 for forming a cylinder engaging-releasing mechanism to a tip part of a cylinder 34 extending in the tool body. The tip tool 35 is attached-detached by a sphere 64, a second fixing member 65, and a second operation sleeve for forming a tool engaging-releasing mechanism to the tool sleeve 51. One compression spring 52 mutually energizes the first and second fixing members in the opposite direction, to maintain the mutual connecting-fixing relationship. When an operation sleeve is moved against energizing force of the compression spring, the mutual connecting relationship is cut off.
