Abstract
(EN)
Provided is an extension and contraction mechanism that enables cost reduction with a convenient mechanism. An extension and contraction mechanism (10) is provided with: a shaft (32) and a back-and-forth pipe (22) disposed coaxially with respect to a reference axis line (J); a motor (28) that rotates the shaft (32); a base-end pipe (20) that holds the back-and-forth pipe (22) non-rotatably and movably back and forth along the reference axis line (J); a plurality of rollers (46) disposed in an inner cavity of the back-and-forth pipe (22); and a roller holder (44) that rotates integrally with the shaft (32) and holds a plurality of rollers (88) rotatably. Each of the plurality of rollers (46) is brought into contact with an outer peripheral face of the shaft (32), and is held by the roller holder (44) such that a central axis thereof forms an inclined angle θ with respect to the reference axis line (J). At least one of an outer peripheral face of the roller (46) and the outer peripheral face of the shaft (32) is an elastic body, and at least one thereof has been subjected to a non-slip treatment.

L'invention concerne un mécanisme de déploiement et de retrait qui permet une réduction des coûts grâce à un mécanisme pratique. Un mécanisme de déploiement et de retrait (10) est équipé : d'un arbre (32) et d’un tuyau de va-et-vient (22) disposé coaxialement par rapport à une ligne d'axe de référence (J) ; d’un moteur (28) qui fait tourner l'arbre (32) ; d’un tuyau d'extrémité base (20) qui maintient le tuyau de va-et-vient (22) non rotatif et mobile en va-et-vient le long de la ligne d'axe de référence (J) ; d’une pluralité de rouleaux (46) disposés dans une cavité interne du tuyau de va-et-vient (22) ; et d’un porte-rouleau (44) qui tourne d'un seul tenant avec l'arbre (32) et maintient rotatifs une pluralité de rouleaux (88). Chaque rouleau de la pluralité de rouleaux (46) est mis en contact avec une face périphérique externe de l'arbre (32), et est maintenu par le porte-rouleau (44) de sorte que son axe central forme un angle θ incliné par rapport à la ligne d'axe de référence (J). Une face périphérique externe du rouleau (46) et/ou la face périphérique externe de l'arbre (32) est un corps élastique, et l’une et/ou l’autre de ces dernières a été soumise à un traitement antidérapant.
