Title:
IMAGING DEVICE
Document Type and Number:
WIPO Patent Application WO/2013/175944
Kind Code:
A1
Abstract:
Provided is an imaging device capable of ensuring airflow between the inside and outside of the device while minimizing the penetration of foreign particles and unwanted light and suppressing the appearance of the foreign particles. When an external thread (21c) and an internal thread (22a) screw together, a D-cut portion (21d) and a protruding portion (21p) are arranged radially outside the inner peripheral ridge (R) of the internal thread (22a) to prevent the creation of a gap through which the other side can be seen in the optical axis direction. Thereby, a kind of labyrinthine structure is created so that even if grit and dust or unwanted light enters through a gap (S), these nuisances can be effectively prevented from entering directly inside a miller cell (22).
