PROBLEM TO BE SOLVED: To provide an approach annunciator for a bicycle capable of surely announcing the approach of the traveling bicycle to the surroundings. SOLUTION: This approach annunciator 1a for the bicycle can be used by being arranged on a front wheel frame 211 among frames 21 of the bicycle 2. In this approach annunciator 1a for the bicycle, when a spoke 23 passes through the periphery of the front wheel frame 211 when a front wheel 22 rotates, the spoke 23 intermittently contacts with the tip of a vibrating part 11. Thus, the vibrating part 11 is elastically deformed to give out an intermittent announcing sound while the bicycle 2 travels. This announcing sound is given out to be announced to a forward side pedestrian of the bicycle 2 and a person unable to visually sense this moving bicycle 2.
