PROBLEM TO BE SOLVED: To provide a rotation driving air tool capable of maintaining lubricating oil for a gear in a drive transmission mechanism of a rotation driving air pump as long as possible. SOLUTION: The rotation driving air tool is provided with: an air motor (14); a rotation transmission mechanism (18) for transmitting a rotation driving force of a rotation output shaft (12) of the air motor to a rotation tool member (15) such as a grinding machine; a motor chamber (20); a rotation transmission chamber (22); a bulkhead (24) between the motor chamber and the rotation transmission chamber; and a housing (28) with an air spraying hole (72) which is provided to pass through the bulkhead and to spray discharge air from the air motor toward a peripheral wall surface of the power transmission chamber.
