Abstract
An oscillation tool includes a grip-portion housing and a front-side housing which are fitted to each other so as to freely slide on each other. In the case that a driving unit and an oscillating unit are distanced from each other, the oscillating shaft is oscillated at a narrow amplitude. On the other hand, in a case that the driving unit and the oscillating unit are approached by each other, the oscillating shaft is oscillated at a wide amplitude.
