Crank-type pressing device and terminal crimping apparatus including the same

A crank-type pressing device comprising:

• a driving source to generate a rotative force;
• a rotator that rotates around a first rotation axis upon receiving the rotative force from the driving source, the rotator including an eccentric portion eccentric from the first rotation axis;
• a bearing supporting the rotator such that the rotator is rotatable;
• a link mechanism including
• a first connection connected to the eccentric portion of the rotator so as to be rotatable around a second rotation axis parallel to the first rotation axis,
• a link arm extending from the first connection in a direction perpendicular to the second rotation axis, and
• a second connection provided in the link arm;
• and
• a pressing member connected to the second connection of the link mechanism so as to be rotatable around a third rotation axis parallel to the first rotation axis and the second rotation axis, the pressing member extending along a pressing axis perpendicular to the first rotation axis, wherein
• the bearing and the eccentric portion are disposed on a same straight line perpendicular to the first rotation axis.
