La présente invention concerne une roue élastique ou une poulie mobile pourvue: d'un noyau de roue; d'une roue qui est disposée à l'extérieur dans la direction radiale du noyau de roue; d'au moins trois broches latérales de noyau de roue qui sont disposées sur le noyau de roue; d'au moins trois broches latérales de roue qui sont disposées sur la roue; et d'un élément tampon qui relie les broches latérales de noyau de roue et les broches latérales de roue dans un état où une tension est appliquée dessus, l'élément tampon étant en plastique renforcé de fibres. La roue élastique ou la poulie mobile utilise l'élément tampon en plastique renforcé de fibres et est donc plus résistante à la détérioration que si l'on utilise un élément tampon en caoutchouc synthétique. De plus, étant donné que la tension est appliquée à l'élément tampon à l'avance, il est possible d'assurer la stabilité de la charge du plastique renforcé de fibres ayant une faible résistance à la compression et une grande résistance à la traction, et la roue élastique ou la poulie mobile peut être légère.
