PURPOSE: A wheel and a key installed on an electric circle saw are provided to enable easy linear cutting of a work piece and minimize the fatigue of a worker because the key is installed on the backside of a cutting unit. CONSTITUTION: A wheel(104) and a key are installed on the bottom of an electric circle saw. The lower end(103) of the saw corresponds to the center of mass of a motor(102) and is formed with a wheel groove in which the wheel is installed. A key groove(107) is formed in a rear part(106) of a saw blade(105). A key spring is installed in the key groove.
