ABSTRACT:
A drive joint mechanism includes a drive shaft (30) and a driven shaft (24) coupled coaxially to the drive shaft (30). A coupling (31) on the drive shaft (30) or the driven shaft (24) has pin-engaging grooves (31a,31b) and at least one pyramid-shaped pin-guide (32) between adjacent pin-engaging grooves (31a,31b). An engagement pin (25) is provided on the other of the drive shaft (30) and the driven shaft (24) and engages the pin-engaging groove (31a,31b). The engagement pin (25) contacts the pin-guide (32) while coupling the drive shaft (30) and the driven shaft (24). Thus, at least one of the drive shaft (30) and the driven shaft (24) is rotated by a pressing force exerted in the axial direction by the driven shaft (24) so that the pin-guide (32) guides the engagement pin (25) into the pin-engaging groove (31a,31b).
