ABSTRACT:
A cam mounting gear having a number of teeth smaller by one than the number of teeth of a main gear which is driven to rotate is disposed in parallel to the main gear, and a cam having a tapered face formed thereon such that the thickness thereof gradually increases along an inner periphery thereof is disposed on an inner wall of the cam mounting gear. A main holder having a cutter blade and a bearing which contacts with the cam is supported for rotation on a flat face portion of the main gear. As rotation of the main gear is transmitted to the cam mounting gear via a pinion, the bearing of the main holder is driven to roll on the tapered face of the cam, and thereupon, the cutter blade is displaced in a direction toward the center of the apparatus to cut a cutting object pipe located at a central location of the apparatus.
