Claims14
A hair clipper comprising:
- a rotary motor that includes a rotary shaft extending in a first direction and a motor drive unit that rotationally drives the rotary shaft;
- a conversion mechanism that is connected to the rotary shaft and converts rotational motion of the rotary shaft into reciprocating linear motion;
- a movable blade that is connected to the conversion mechanism and performs reciprocating linear motion;
- a fixed blade with which the movable blade is in sliding contact;
- a bearing that is provided in the motor drive unit to support the rotary shaft with a clearance provided between the bearing and a peripheral surface of the rotary shaft;
- at least one shaft stopper that presses the rotary shaft in at least one direction in directions intersecting the first direction to restrict shaft shaking during rotation of the rotary shaft caused by the clearance while allowing rotation of the rotary shaft;
- and
- a support part that supports the shaft stopper, wherein
- the at least one shaft stopper is a beam extending in a direction intersecting the first direction.
