A fitting structure has a power transmission member (323) which includes first and second tooth sections (161, 162) arranged at intervals at the outer peripheral edge of the power transmission member and to which power is transmitted, and the fitting structure also has a fitting member (600) which is placed so as to surround the power transmission member (323), has formed therein first recesses (163) for receiving the first tooth sections (161) and second recesses (164) for receiving the second tooth sections (162), and fits to the power transmission member (323). The distance between the outer surface of a first tooth section (161) and the inner surface of a first recess (163) is set greater than the distance between the outer surface of a second tooth section (162) and the inner surface of a second recess (164), and an elastically deformable cushioning member is provided between the outer surface of the first tooth section (161) and the inner surface of the first recess (163). L'invention porte sur une structure de montage comprenant un élément de transmission d'énergie (323) comportant des première et seconde sections dentées (161, 162) disposées à intervalles sur le bord périphérique extérieur de l'élément de transmission d'énergie et auxquelles est transmise l'énergie. La structure de montage comprend également un élément de montage (600) placé de façon à entourer l'élément de transmission d'énergie (323) et contenant des premiers évidements (163) destinés à recevoir les premières sections dentées (161) et des seconds évidements (164) destinés à recevoir les secondes sections dentées (162) et s'adaptant sur l'élément de transmission d'énergie (323). La distance entre la surface extérieure de la première section dentée (161) et la surface intérieure du premier évidement (163) est supérieure à la distance entre la surface extérieure de la seconde section dentée (162) et la surface intérieure du second évidement (164), et un élément d'amortissement élastiquement déformable est disposé entre la surface extérieure de la première section dentée (161) et la surface intérieure du premier évidement (163).
