Abstract: In a stowing mechanism of a vehicular door mirror device, sound is produced when a gear plate is rotated from a state in which a clutch plate has been disengaged from the gear plate and the clutch plate engages with the gear plate under biasing force from a coil spring. Butyl tape spans between a portion of the coil spring on an upper side of a gap and a portion of the coil spring on a lower side of the gap such that vibration of the coil spring is suppressed. Accordingly, the sound is able to be damped.

Abstract: The tomographic image capturing device of the present invention includes a tomographic image capturing means that scans measurement light on a subject's eye fundus (E) to capture tomographic images of the subject's eye fundus and an image processing means that compresses a picture of the captured tomographic images in a scan direction to generate a new tomographic picture.
