摘要

PPROBLEM TO BE SOLVED: To provide a push roller fore-and-aft movable mechanism avoiding contact with a dump truck by accurately setting a distance between a front end of a main body frame in a road paving machine and a push roller to be a distance corresponding to the kind and size of the dump truck. PSOLUTION: An upper plate 16 and a lower plate 17 are protrusively provided at a front end portion 15a of a main body frame 15. On the lower plate 17, a first mounting pin hole 17a and a second mounting pin hole 17b are bored at a required interval in a traveling direction of a road paving mechanism 14. On the upper plate 16, a mounting long hole 16a having both ends which are positioned respectively corresponding to the first mounting pin hole 17a and the second mounting pin hole 17b is bored on the upper plate 16. A push roller pin 18a is inserted in the first mounting pin hole 17a or the second mounting pin hole 17b, thereby setting distances between the front end portion 15a of the main body frame and push rollers 7, 7 to be a first length distance or a second length distance.
