In addition, if this space is secured, the arrangement space for other members within the housing structure will be squeezed. Therefore, it is difficult to freely design a racing engine. Further, when the spool is rotated only by driving the gear motor, there is a possibility that the string cannot be loosened immediately in an emergency such as when the gear motor fails.

Abstract

Le boîtier du module de course selon la présente invention loge au moins une partie d'un arbre de bobine et loge une unité d'entraînement rotative. La surface supérieure d'un couvercle recevant une partie corps autour de laquelle un cordon peut être enroulé s'étend dans une direction qui croise la direction verticale. Une paroi interne s'étend vers le bas depuis la surface supérieure et entoure la partie corps lorsqu'elle est vue dans la direction verticale. Une paroi externe s'étend vers le bas depuis le bord externe de la surface supérieure et est disposée radialement vers l'extérieur depuis la paroi interne. Une sortie traverse la paroi externe. La paroi interne a une paire de parois de guidage se faisant face à travers la partie corps. Chacune des parois de guidage s'étend au moins vers la sortie et est reliée au bord de la sortie. L'espace entre la paire de parois de guidage dans la direction de face devient plus étroit de l'axe de rotation vers la sortie.
