Abstract
Provided is a belt-type grinding tool allowing an endless grinding belt replacement operation to be performed without requiring a large force. A belt-type grinding tool has an endless grinding belt wound around a drive pulley provided in a tool body and an idler pulley rotatably supported by a pulley support bar. The grinding tool has a spring urging the pulley support bar forward relative to the tool body, thereby causing the idler pulley to press the endless grinding belt forward to apply a tension to the endless grinding belt, and a spring support member movably attached to the tool body to support and compress the spring, the spring support member being movable between a first position where the idler pulley applies a tension to the endless grinding belt and a second position where the spring support member is displaced from the first position to reduce the amount of compression of the spring to reduce the tension.
