Abstract
(EN)
Provided is a power transmission device with which image blurring of a display image is not a concern. A power transmission member (65) has a pair of wall parts (65c, 65d) facing each other with a second extension part (42e) interposed therebetween. One wall part (65c) among the pair of wall parts (65c, 65d) is provided with a protrusion part (65h) protruding toward the second extension part (42e). The other wall part (65d) among the pair of wall parts (65c, 65d) is provided with a leaf spring (65i). Both a first abutment part (T1) on which the protrusion part (65h) and the second extension part (42e) abut and a second abutment part (T2) on which the leaf spring (65i) and the second extension part (42e) abut are not located on a virtual line (70) extending in parallel to an axial direction X.

La présente invention concerne un dispositif de transmission de puissance avec lequel un floutage d'image d'une image d'affichage n'est pas un problème. Un élément de transmission de puissance (65) présente une paire de parties de paroi (65c, 65d) se faisant face avec une seconde partie d'extension (42e) interposée entre celles-ci. Une partie de paroi (65c) parmi la paire de parties de paroi (65c, 65d) est dotée d'une partie de saillie (65h) faisant saillie en direction de la seconde partie d'extension (42e). L'autre partie de paroi (65d) parmi la paire de parties de paroi (65c, 65d) est dotée d'un ressort à lames (65i). À la fois une première partie de butée (T1) sur laquelle la partie en saillie (65h) et la seconde partie d'extension (42e) viennent en butée et une seconde partie de butée (T2) sur laquelle le ressort à lames (65i) et la seconde partie d'extension (42e) viennent en butée ne sont pas situées sur une ligne virtuelle (70) s'étendant parallèlement à une direction axiale (X).
