As described above, according to the present invention, when the belt mainly made of an elastic material has a predetermined amount of wear on the sliding contact surface at a predetermined depth from the sliding contact surface with the rotating wheel, the amount of wear on the sliding contact surface is fixed. The limit has been reached
By direct contact of the rotary wheel in order to aurally recognize the bets
Since hard member that emits different sounds for wear alarm is embedded,
When the hard member exposed on the sliding contact surface in direct contact with each rotating wheel in response to the wear of the belt mainly generates abnormal noise, the driver is notified that the wear amount of the sliding contact surface has reached a predetermined limit.
Etc. can be recognized very easily and effectively . Moreover, the above-mentioned noise generated by the hard member causes the member to rotate.
Because it is a simple contact sound emitted by direct contact with the ring,
The hard portion acting as a wear amount detecting means for the belt main body
The material can be used as the alarm sound generation means as it is
Can greatly contribute to the simplification of device configuration and cost savings.
