Abstract
A power tool includes a motor; an output part configured to be rotated around a rotational axis in response to energization of the motor; a plurality of lights disposed spaced apart around the output part; and an optical member having a refractive surface that refracts illumination light emitted from a light-emitting surface of one of the lights such that the main illumination direction extends at an angle away from the rotational axis.
Claims23
A power tool comprising:
- a motor;
- an output part configured to be rotated about a rotational axis in response to energization the motor;
- lights disposed spaced apart around the output part;
- a circuit board having a support surface that supports the lights;
- an optical member disposed such that the optical member opposes a light-emitting surface of one of the lights;
- and
- a cover member, which has at least a portion that is disposed more forward than the circuit board, is formed of a material that differs from the material of the optical member, and is formed integrally with the optical member.
