1. A pressing device comprising:
a pressure lever that is platy and has a thickness t, the pressure lever configured to pivot;
a cam configured to press the pressure lever; and
a cam follower mounted on the pressure lever and disposed opposite the cam, the cam follower configured to transmit pressure from the cam to the pressure lever,
the cam follower having a contact face configured to contact the cam and a side face being perpendicular to the contact face, the contact face having a length W in a thickness direction of the pressure lever and a length L1 in an orthogonal direction perpendicular to the thickness direction of the pressure lever, the length L1 defined from a contact position where the cam follower contacts the cam to the side face of the cam follower,
the thickness t, the length W, and the length L1 satisfying a relation defined by
L1≥0.6×(W−t)/2+0.2.
