PROBLEM TO BE SOLVED: To provide a conveyor roller that makes a reduced vibration and noise and is durable, when used for conveying loads. SOLUTION: The conveyor roller comprises (a-1) 100-85 wt.% of a hydrogenated block copolymer which is obtained by hydrogenating a block copolymer consisting of at least two of polymer blocks A<SB>1</SB>mainly comprising a vinyl aromatic compound and at least one of polymer blocks B<SB>1</SB>comprising mainly a conjugated diene compound and (a-2) 0-15 wt.% of a block copolymer component consisting of at least two of polymer blocks A<SB>2</SB>mainly comprising a vinyl aromatic compound and at least one of polymer blocks B<SB>2</SB>comprising mainly a conjugated diene compound. The conveyor roller is molded from a thermoplastic elastomer composition which is obtained by crosslinking, in the presence of a peroxide and a crosslinking assistant, a composition consisting of (a) 100 pts.wt. of the block copolymer, (b) 100-350 pts.wt. of a softening agent, (c) 20-80 pts.wt. of a polypropylene resin, (d) 0-300 pts.wt. of a polyethylene resin, and (e) 0-100 pts.wt. of an inorganic filler.
