PROBLEM TO BE SOLVED: To enable an operator seated on a cab to easily visually see the right and left side ends of a forward rolling compaction roller. SOLUTION: A virtual line connecting a moved position A1 at the time when the eye point A of the operator M seated on the cab 39 is moved to a left side and the left side end B1 of the forward rolling compaction roller 14 is made C1, another virtual line connecting the moved position A2 at the time when the eye point A of the operator M is moved to a right side and the right side end B2 of the forward rolling compaction roller 14 is made C2, and then, width dimension L4 between the right and left sides of a front car body 32 is set at length within the width dimension regulated by the virtual lines C1, C2. Thereby the virtual lines C1, C2 are not shielded by the front car body 32, and the operator M can easily visually see the right and left side ends B1, B2 of the forward rolling compaction roller 14 through the virtual lines C1, C2 only by tilting his or her neck right or left as he or she seats on the center part of the cab 39.
