Abstract: A grinder (100) includes a motor (12), a housing (4, 6, 30), a spindle (24), a first cover (120), and a second cover (170). The spindle protrudes downward from the housing, is driven by the motor, and thereby rotates. The first cover is provided in the circumferential direction of the spindle, is fixed to the housing, and at least partially covers a tool accessory (40), which is mounted on the spindle, from above. The second cover is detachably mounted on the housing (6) independently of the first cover.

Abstract: An oscillating rotary electric power tool, in which a spindle with a distal end tool attached thereto is projected downward from a front end portion of a housing accommodating a motor, and the housing also accommodates a coupling member rotatable integrally with an output shaft of the motor, a crankshaft fitted with the coupling member in a depression and projection fitting structure, and a link member to which the spindle is fixed and power is transmitted from the crankshaft to rotate clockwise and counterclockwise in an oscillating manner so that the link member will be driven by the motor to rotate the spindle clockwise and counterclockwise in the oscillating manner, wherein an elastic body is interposed between the coupling member and the crankshaft in the same axial direction as the output shaft.
