PURPOSE: To provide the hair dryer having a voltage switching means which is scarcely damaged, even if a substitute article such as a coin, etc., is used at the time when a rotary operating piece of a manual voltage switching means is subjected to rotational operation.

CONSTITUTION: The hair dryer is constituted so that a rotary operating piece 2 of a voltage changeover switch of a manual voltage switching means 1 is exposed on the outside surface of a hair dryer A main body, a groove body 21 in the diameter direction is formed in the head part of this rotary operating piece 2, and in the periphery of the hair dryer A main body of the exposed rotary operating piece 2, a projecting part 10 is formed in the outside of a rotatable range for switching a voltage, and in the case the rotational operation is executed by inserting a coin in the groove body 21, the coin protrudes from the groove body 21, the coin abuts on the projecting part 10 at the time of rotational operation, and the rotary operating piece cannot rotate to the outside of a range in which the rotational operation is possible.
