A grinder (1) comprises a body having an annular portion (62), a wheel cover (40) which is attachable to the annular portion (62), and a wheel cover holding member (70) which holds the wheel cover (40). The wheel cover (40) has a cylindrical portion (42) which is attachable to the annular portion (62). The wheel cover holding member (70) has a slide member (71) and a pressing portion (91) which moves the slide member (71) . The pressing portion (91) switches a state between an engagement state in which the slide member (71) is engaged with the cylindrical portion (42) and a disengagement state in which the slide member (71) is disengaged with the cylindrical portion (42) by moving the slide member (71). The pressing member (91) moves on a second line which is parallelly offset from a first line passing the center of the annular portion (42) in a predetermined direction. |
