ABSTRACT:
A power tool has a light unit provided at the bottom part of the handle grip. The light unit can be adjusted to change the lighting angle and can hold the desired lighting angle. The light unit thus disposed does not get in the way, the lighting angle of the light unit is variable and the emitted light does not shake, depletion of the power supply due to the light switch of the light unit being left on is prevented, shadows of the end tool are not easily produced by light from the light unit, lighting contrast is high, wiring failures and continuity faults in the light-emitting element do not occur easily, and a small, economical power tool can be provided. The light-emitting element of the light unit is a yellow LED. The light unit turns off automatically at a predetermined time after the light turns on.
