1. A driving tool comprising:
a striking unit configured to move in a first direction to strike a fastener;
a first transmission portion provided on the striking unit;
a rotating member configured to rotate in a first rotation direction; and
a second transmission portion provided on the rotating member and configured to be engaged with and released from the first transmission portion,
wherein the striking unit is configured to move in a second direction opposite the first direction when the second transmission portion is engaged with the first transmission portion, and configured to move in the first direction when the second transmission portion is released from the first transmission portion,
wherein the second transmission portion includes:
a first engaging portion arranged along the first rotation direction of the rotating member and configured to move along the first rotation direction when the rotating member rotates so that the first engaging portion is engaged with the first transmission portion to move the striking unit in the second direction; and
a second engaging portion configured to move in the first rotation direction so that the second engaging portion is engaged with the first transmission portion to move the striking unit in the second direction, and configured to move in a third direction different from the first rotation direction so that the second engaging portion is released from the first transmission portion, and

wherein the rotating member is provided with a guide portion elongated in a radial direction of the rotating member, and the second transmission portion is configured to be released from the first transmission portion when the second engaging portion is configured to move in the third direction along the guide portion toward an inner side of the rotating member from an initial position by a load received from the first transmission portion as a reaction force of a rotational force to rotate the rotating member in the first rotation direction in a state where the second engaging portion is in contact with the first transmission portion to move the striking unit in the second direction.
