To provide a rotary toothbrush with a horizontally or vertically rotatable head part, which does not have such a trouble that the head part rotates leftward or rightward during tooth-brushing and can stably brush teeth.
A rotary toothbrush includes: a handle with a lever; an operating rod operated together with the lever to linearly move in a length direction of the handle; a tilting member 400 coupled to tilting guide grooves of the operating rod to thereby be tilted when the operating rod moves forward;; a head part 200 having a rotation shaft rotatably fixed to the tilting member 400 to thereby be tilted together with the tilting member 400 and having bristles implanted therein; a rotation drive member 500 which is connected to the rotation shaft, rotates the rotation shaft when the operating rod is moved forward, thereby allowing the head part to form a T shape with respect to the handle; and a first fixing part which is provided between the handle and the lever and fixes the lever in a state in which the lever is rotated forward or rearward.
