PROBLEM TO BE SOLVED: To provide a conveyance machine with two-degree of freedom capable of changing and setting a conveyance direction with a simple structure. SOLUTION: This conveyance machine is provided with first rollers 11 having a rotary shaft of a first direction and divided into two types of rollers driven integrally with alternate ones, respectively, second rollers 12 having a rotary shaft in a second direction orthogonal to the first one, a bridging member 13 acting as a bridge between the rollers 11, 12 and relieving difference in level, and a mounting base 14 for mounting and supporting or storing the rollers 11, 12, and the bridging member 13. It has a structure capable of setting the conveyance direction by differentiating friction coefficients including a coefficient of dynamic friction and that of static friction between the first roller 11 and the second roller 12, and an article to be conveyed for each of the directions of the rotary shafts of the rollers.
