Accordingly, the handpiece can solve problems such as rotational power loss, noise, micro vibration, durability degradation, and volume increase, which result from the gear connection structure of a conventional rotational force transfer shaft portion, which is complicated. A handpiece according to the present invention comprises: a body portion having a handle formed thereon; a head portion to which a tool is coupled; and a rotational force transfer shaft portion for transferring a rotational force from a rotational power source provided on a side of the body portion to a side of the head portion. The rotational force transfer shaft portion has a predetermined section configured as a spiral spoke portion, which has a helical-type spiral shape. Accordingly, the rotational force transfer shaft portion can independently bend toward a side of the head portion from the part on which the spiral spoke portion is formed. The rotational force transfer shaft portion extends, through the spiral spoke portion part, to a side of the head portion that deviates from the rotational center axis of the rotational power source such that the rotational force can be transferred to a side of the head portion.
