Abstract: A cutting device includes a support shaft; a first blade body which holds the support shaft; a rolling bearing which is mounted on the support shaft, and has an outer race and an inner race; a second blade body which is provided to overlap the first blade body, and is rotatably supported on the support shaft via the rolling bearing; a fixing member which is disposed on the support shaft on a side opposite to the first blade body across the rolling bearing; and a biasing member disposed between the rolling bearing and the fixing member. One of the outer race and the inner race rotates integrally with the second blade body, and the other of the outer race and the inner race is biased toward the first blade body by the biasing member.
