Abstract
Provided is a handpiece in which a predetermined section of a rotational power transmission shaft includes a plurality of flexible rods. The single rotational power transmission shaft is able to change the direction of the rotation center axis of a rotational power source in order to overcome problems, such as rotational power loss, noise, fine vibration, reduced durability, or an increase in volume, caused by a complicated gear connecting structure of a rotational power transmission shaft for changing the direction of the rotation center axis of the rotational power transmission shaft of a related-art rotational power source.
