Abstract
An impact rotary tool includes a hammer, an anvil, an output shaft, a housing, a bearing (first bearing), and a buffer member. The buffer member includes an elastic member. The anvil has a first facing region. The output shaft has a second facing region. The buffer member is interposed between the anvil and the output shaft. The buffer member regulates a gap distance between the second facing region and the first facing region such that when a maximum load is transmitted from the hammer to the elastic member, the second facing region faces the first facing region with a gap left between the second facing region and the first facing region in a thrusting direction.
