PROBLEM TO BE SOLVED: To divisionally use the continuous ringing sound and only one single ringing sound according to the circumstances by providing a bell with both of a continuous ringing mechanism and a single ringing mechanism. SOLUTION: When a free end of a pull lever 16 is pulled by a finger, a rotator 14 is rotated in a predetermined direction through a gear mechanism, the rotator 14 is reversed when the pull lever 16 is released, and the rotary rings at both ends are contacted with a projection on an inner surface of a cup-shaped ringing cover 19 in accompany with the continuous forward and backward rotations to generate the continuous ringing sound. When the pull lever 18 is moved in the direction separated from the ringing cover 19 against the elastic force of a soft elastic member 17 by the finger, and then released, the pull lever is inclined to an opposite side with respect to a central shaft by the elastic reaction force of the soft elastic member 17, and contacted with an outer peripheral surface of the ringing cover 19 to generate only one single ringing sound.
