Patent number: 11491917Abstract: A tilting mechanism of a view device for a vehicle has a configuration in which a rotating section is rotatably supported on a shaft of a fixed portion. A helical compression spring is fitted onto the shaft. A plate is attached to the free-end side of the shaft via a washer. An outer circumferential surface of the shaft and a center hole of the washer include respective different diameter portions. A gap g in a radial direction is formed between the outer circumferential surface of the shaft and an inner circumferential surface of the center hole of the washer. The tilting mechanism includes a deviation mechanism. The deviation mechanism makes the gap g become narrow or zero at the different diameter portions at at least one place, the different diameter portions facing each other, by making the washer move relative to the shaft in the radial direction.Type: GrantFiled: August 30, 2021Date of Patent: November 8, 2022Assignee: MURAKAMI CORPORATIONInventors: Toshiharu Yamashita, Yoshiaki Nagashima
