Manufacturing apparatus for drive disk

A manufacturing apparatus for a drive disk, the drive disk comprising:

• a plurality of drive rollers each including a supporting shaft protruding from both sides thereof;
• and
• a disk body having a plurality of slots arranged in a circumferential direction around a prescribed central axis and configured to receive the drive rollers,
• wherein each slot is partially defined by a pair of opposed surfaces opposed to each other at a space radially outside the supporting shaft of each drive roller and arranged orthogonally to the supporting shaft, and
• the opposed surfaces are inclined to the central axis,
• the manufacturing apparatus comprising:
• an upper member and a lower member configured to form a whole of the disk body;
• and
• a drive unit configured to drive the upper member and the lower member in a moving direction along the central axis,
• wherein the upper member and the lower member each include a base and protrusions protruding from the base along the moving direction,
• each protrusion is defined by a plurality of surfaces including a first side surface inclined with respect to the opposed surfaces and a second side surface parallel to the opposed surfaces,
• the first side surface of the protrusion of the upper member and the first side surface of the protrusion of the lower member are parallel to each other and face away from each other,
• the second side surface of the protrusion of the upper member and the second side surface of the protrusion of the lower member face away from each other,
• the first side surface of the protrusion of the upper member and the first side surface of the protrusion of the lower member come into contact with each other to form the slot.
