Geometric relations among components of a wheel angle shift mechanism of a cutting apparatus for cutting paved roads are theoretically determined by utilizing trigonometric and inverse trigonometric functions so that wheel angles are changed and fixed by a one-touch handling for a precise circular or straight movement of the cutting apparatus for a circular or straight cutting operation. Based on calculations the cutting apparatus is arranged as follows. A support axis of a centering jig 8 is detachably inserted into a support point S0, being functioned as a cutting center, of a chassis BS equipped with two pairs of front wheels and a pair of rear wheels. A wheel angle shift mechanism K for shifting as desired from a straight movement to a circular movement and vice versa is arranged between a pair of the rear wheels. A first rear wheel and a second rear wheel having respective vertical revolving axes 1 and 2 are arranged so as to face each other at offset positions of respective wheels. The respective revolving axes 1 and 2 are inserted into and supported by cylinder bearings 1a and 2a vertically fixed to a base frame of the chassis BS so as to revolve horizontally. Angle shifts from the circular movement to the straight movement and vice versa, are performed by the one-touch handling of a shift lever 5 attached to the wheel angle shift mechanism K.
