Title (EN) ROTATION POSITION HOLDING MECHANISM
(FR) MÉCANISME DE MAINTIEN DE POSITION DE ROTATION

Abstract:
(EN) [Problem] To provide a rotation position holding mechanism which appropriately biases a locking member while simplifying the shape of the biasing member. [Solution] A rotation position holding mechanism for locking the rotation of an output rotating body when a rotary drive force is not being inputted, the rotation position holding mechanism being characterized in that: a biasing member 145 for biasing a locking member, which locks the rotation of an output rotating body when pressed into the tip-end side of a wedge-shaped space, is equipped with a folded-back section 145a which is a flat spring that is folded back upon itself so as to take on a rounded shape having a larger diameter d3 than the width d1 of an opening 124a, and is housed inside a holding groove 124, and a pair of wing parts 145b obtained by bending the pair of sections, which extend from the folded-back section 145a and pass through the opening 124a, only a single time each so as to separate from one another; and the wing parts 145b bias the locking member.
(FR) Le problème décrit par la présente invention est de fournir un mécanisme de maintien de position de rotation qui sollicite de manière appropriée un élément de blocage tout en simplifiant la forme de l'élément de sollicitation. La solution selon l'invention porte sur un mécanisme de maintien de position de rotation permettant de bloquer la rotation d'un corps rotatif de sortie lorsqu'une force d'entraînement rotative n'est pas appliquée, le mécanisme de maintien de position de rotation étant caractérisé en ce que : un élément de sollicitation (145) permettant de solliciter un élément de blocage, bloquant la rotation d'un corps rotatif de sortie lorsqu'il est pressé dans l'extrémité de pointe d'un espace en forme de coin, est équipé d'une section repliée (145a) qui est un ressort plat replié sur lui-même de façon à prendre une forme arrondie possédant un diamètre plus grand (d3) que la largeur (d1) d'une ouverture (124a) et est logé à l'intérieur d'une rainure de maintien (124) et est équipé d'une paire de parties aile (145b), obtenue par pliage de la paire de sections, qui s'étend à partir de la section repliée (145a) et passe à travers l'ouverture (124a), seulement une seule fois chacune de façon à se séparer l'une de l'autre ; et les parties aile (145b) sollicitent l'élément de blocage.
(JA) 【課題】ロック部材を適切に付勢しつつも付勢部材の形状が簡略化された回転位置保持機構を提供する。 【解決手段】回転駆動力の非入力時に出力回転体の回転をロックする回転位置保持機構において、楔状空間の先端側に押し込まれると出力回転体の回転をロックするロック部材を付勢する付勢部材145が、板バネであって、開口124aの幅d1よりも大径d3の丸みを帯びて折返されて保持溝124に収容される折返し部145aと、折返し部145aから開口124aを通って延出する一対の部分が互いに離れる方向に各々1箇所だけ折り曲げられてなる一対の羽部145bと、を有し、その羽部145bがロック部材を付勢することを特徴とする。
