A motor driven bell for producing a sound of a bell in a manner that a hammer member hits a gong through the use of a driving force of a motor. The motor driven bell comprises a supporting shaft A1 born on a front side between a pair of opposed frames, a forward and backward swingable shaft A2 suspended by a suspending arm A3 under the supporting arm A1, a supporting shaft B1 born at a rear portion between the pair of frames, and a forward and backward swingable shaft B2 suspended by a suspending arm B3 under the supporting shaft B1, a forward and backward swingable hammer member held by the swingable shafts A2, B2, and a gong to be hit with the hammer member. A crank mechanism is provided for converting rotation of a shaft of the drive motor into a swinging motion of the swingable shaft B2, thereby hitting the gong by the hammer member to produce the bell sound.
