Abstract
(EN)
This locking plate 60 for restricting the rotation of a gear 30 composing a transmission gear mechanism 28 for transmitting rotational motion from a first motor 10 to a motion conversion mechanism 4 comprises a base 601, a protrusion 602 that protrudes from the base 601 and can be inserted into a hole 30a in an axial-direction end surface 30b of the gear 30, and a pair of contact parts 603 that are provided on both sides of the protrusion 602 in the width direction and each have an end surface 603a that can be brought into contact with the axial-direction end surface 30b of the gear 30. A pair of notches 604 that are recessed further toward the base 601 side than the end surfaces 603a of the contact parts 603 are provided between the protrusion 602 and the contact parts 603. Each notch 604 has a widening part 606 that is connected to the base 601 side of the protrusion 602 and has a width direction dimension W3 that widens toward the base 601 side.

L'invention concerne une plaque de verrouillage 60 permettant de limiter la rotation d'une roue 30 composant un mécanisme d'engrenage de transmission 28 servant à transmettre un mouvement de rotation d'un premier moteur 10 à un mécanisme de conversion de mouvement 4 comprenant une base 601, une saillie 602 en saillie de la base 601 et pouvant être insérée dans un trou 30a ménagé dans une surface d'extrémité dans la direction axiale 30b de la roue 30, et deux parties de contact 603 disposées des deux côtés de la saillie 602 dans la direction de la largeur et comportant chacune une surface d'extrémité 603a pouvant être amenée en contact avec la surface d'extrémité dans la direction axiale 30b de la roue 30. Deux encoches 604 plus évidées vers le côté base 601 que les surfaces d'extrémité 603a des parties de contact 603 sont disposées entre la saillie 602 et les parties de contact 603. Chaque encoche 604 comporte une partie allant en s'élargissant 606 reliée au côté base 601 de la saillie 602 et ayant une dimension dans la direction de la largeur W3 qui va en s'élargissant vers le côté base 601.
