PURPOSE: A pin holder for a calendar is provided to rapidly and firmly bind a book by inserting a pin holder to a binding part of a calendar formed of multiple sheets and melting and press-molding and end of the pin holder. CONSTITUTION: A pin holder for a calendar comprises a body (12) and a fixing pin (15). The fixing pin is formed in the center of the body. The body and the fixing pin are formed of a synthetic resin. The fixing pin is inserted in a pin hole (104) of a binding part (102), and an exposed distal end part (15') is melted by a heating unit and pressed and expanded by a press-molding unit. A reentrant groove (16) is formed in an end of the fixing pin at a predetermined depth. |
