Abstract
A power tool includes a motor, an output shaft, a chip-on-board light emitting diode, and a light cover. The output shaft is rotated by a rotational force of the motor. The chip-on-board light emitting diode is disposed around the output shaft. The chip-on-board light emitting diode includes: a substrate having a circular ring portion; and an LED chip disposed on a front surface of the circular ring portion. The light cover is fixed to the substrate. The light cover includes: an inner cylindrical portion disposed radially inside with respect to the circular ring portion; and a light transmission portion through which light emitted from the LED chip passes. The inner cylindrical portion includes a cover slope that totally reflects light from the LED chip forward.
