In a speed reducer provided with a shock absorbing rubber damper disposed to a power transmission path from a first wheel to which a driving force of a motor is input to a second wheel from which the power is taken out, first projecting portions 3e, auxiliary projecting portions 3f and second projecting portions 5b formed to a first wheel 3 and a second wheel 5 are disposed together in the intervals T between divided rubber dampers 6 as well as receiver plates 7, 8 are attached to the end surfaces 6a, 6b of the rubber dampers 6 serving as surfaces confronting the projections 3e, 3f and 5b so as to approximately entirely cover the end surfaces. Respective two receiver plates 7, 8 disposed to the end surfaces 6a, 6b are arranged as integrally formed receiver plate units U. With this arrangement, a shock absorbing capability is enhanced as well as the number of parts can be reduced.

Cette invention concerne un réducteur de vitesse dans lequel un amortisseur de choc en caoutchouc est disposé sur une voie de transmission de puissance d'une première roue entraînée par un moteur vers une seconde roue de prise de force et comporte une première série de saillies 3e, des saillies auxiliaires 3f, une deuxième série de saillies 5b formées sur la première roue 3 et la seconde roue 5 dans les intervalles T entre amortisseurs en caoutchouc 6, ainsi que des plaques réceptrices 7, 8 fixées aux surfaces d'extrémité 6a, 6b des amortisseurs en caoutchouc 6 servant de surfaces antagonistes aux saillies 3e, 3f et 5b de façon à couvrir presque entièrement les surfaces d'extrémité. Les deux plaques réceptrices 7, 8 disposées par rapport aux surfaces d'extrémité 6a, 6b sont agencées pour constituer des unités réceptrices intégrales U. Selon cette disposition, la capacité d'absorption des chocs est augmentée tout en réduisant le nombre de pièces.
