Abstract: A tool-holding apparatus (70) includes an engaging member (71) for engaging a tool accessory (B) and being movably supported in axial and radial directions in a rotational-output shaft (26) having an insertion hole (81) for holding the tool accessory (B). A first biasing member (72) biases the engaging member towards engagement with the engaging member. A bit sleeve (73) is movable in the axial direction along an outer-circumferential surface of the rotational-output shaft between a blocking position at which radial outward movement of the engaging member is blocked and a permitting position at which radial outward movement of the engaging member is permitted. A second biasing member (74) biases the bit sleeve toward the blocking position. A positioning part (75) is fixed on the outer-circumferential surface of the rotational-output shaft and stops the bit sleeve at the blocking position.
