Abstract

PROBLEM TO BE SOLVED: To ring a bell by action in both directions to draw and push of an operation part by operating rotational movement against a shaft part bowl engaging with an inscribed gear formed in an operating rotational movement bowl and journaling a gear group transmitting a bell tinkler through a winding spring. SOLUTION: When an operating rotational movement bowl 11 is rotationally moved in one direction by an operation part 13, a connecting edge corresponding to the rotationally moving direction winds up a winding spring 16 against the spreading force. By the rotational movement, a small diameter gear part 7a engaged with the internal gear of the operating rotational movement bowl 11 is rotated, the rotation is increased by first and second intermediate gears 7a, 7b, 8a, 8b and transmitted to the pinion part 6a of a bell tinkler 6, and the bell tinkler 6 is rotated at high speed so as to tinkle a bell bowl 2 made of metal. When a finger is released from the operation part 13, the operating rotational movement bowl 11 is rotationally moved in the return direction by the spreading force of the winding spring 16, reverse rotation due to the rotational movement is transmitted from the internal gear of the operating rotational movement bowl 11 to the bell tinkler 6, and the bell bowl 2 is tinkled. Hereby, operability for bell tinkling can be improved.
