One of the first and second molds comprises a base whose surface has undergone a roughening treatment and a coating layer formed by subjecting the surface of the base to a coating treatment. A stamper attachment side is formed on the surface of the coating layer. Since the coating layer is formed by subjecting to a coating treatment the base surface which has undergone a surface-roughening treatment, the base / coating layer contact area can be increased. The adhesion between the base and the coating layer can hence be increased. Consequently, the coating layer is less apt to peel off and the mold can have improved durability.

The side handle is used for controlling a curved path and a straight path for front wheel steering, and the three-wheel mower can walk straightly; the movement area is larger; when a steering control handle (m1) arranged on a panel does not strain a stay cord and a guide bolt head (s2t) arranged on the head of a guide bolt (s2) enters a shaft pit (s5) formed in a front wheel vertical shaft (t10), a front wheel can be made to walk straightly but not steer; when the steering control handle (m1) arranged on the panel strains the stay cord, the stay cord strains the guide bolt head (s2t) through a guide bolt stay cord hole (s2h), and when the guide bolt head (s2t) arranged on the head of the guide bolt (s2) gets away from the shaft pit (s5) formed in the front wheel vertical shaft (t10), the front wheel is made to walk in the curved path. The guide bolt head (s2t) arranged on the head of the guide bolt (s2) is logarithmic spiral cam meshed with the shaft pit (s5) which has a logarithmic spiral and is formed in the front wheel vertical shaft (t10).
