A belt device for driving an elevator having an increased standstill holding capability to maintain the stopped state of a car even if oil or water is adhered between a belt and pulleys. The belt (4) is wrapped around the plurality of pulleys (1), (2), and (3) and rotated by the rotation of the pulleys (1), (2), and (3). The coefficient of friction of the contact surface of the belt (4) on at least the driving pulley (1) is set to 0.6 to 3.0, and the contact surface is formed of a wear-resistant rubber having a hardness (IRHD) of 65 to 95 and a Taber abrasion (requirements specified in ISO547-1- 1999: wear ring: H18, load: 1 kg, speed: 1000 rpm) of 5 to 300 mm3.

Un dispositif de courroie pour diriger un ascenseur, ayant une capacité de maintien fixe améliorée pour maintenir l'état arrêté d'une voiture, même si de l'huile ou de l'eau a adhéré entre une courroie et des poulies. La courroie (4) est enroulée autour des diverses poulies (1), (2) et (3) et amenée à pivoter par la rotation des poulies (1), (2) et (3). Le coefficient de friction de la surface de contact de la courroie (4) sur au moins la poulie de direction (1) est définie sur 0,6 à 3,0 et la surface de contact est formée d'un caoutchouc résistant à l'usure ayant une dureté (IRHD) de 65 à 95 et une abrasion Taber (exigences spécifiées dans la norme ISO547-1-1999) : anneau d'usure : H18, charge : 1 kg, vitesse : 1000 tpm) de 5 à 300 mm?3¿.
