PERIPHERY IMAGING DEVICE
Document Type and Number:
Japanese Patent JP2015174626
Kind Code:
A
Abstract:
PROBLEM TO BE SOLVED: To provide a periphery imaging device capable of reducing an amount of adhesion of water droplets to a lens.SOLUTION: A periphery imaging device 1 comprises: a housing 20; a lower part imaging device 30 housed in the housing 20 and having a lens 33; and a water droplet guiding part 50 disposed on a surface 21 of the housing 20. The water droplet guiding part 50 comprises: a front side guiding part 52 disposed in front of the lens 33; and side guiding parts 51 disposed on a rear part of the front side guiding part 52 and extending in a cross direction of a vehicle V, and disposed on both sides of the lens 33. When the water droplet guiding part 50 is projected on a reference plane with an optic axis of the lens 33 serving as a normal line, angles θ1, θ2 formed with a reference line Cb which is parallel in the cross direction to at least one of normal lines Ca1 contacting outer edges 51d of the side guiding parts 51 and normal lines Ca2 contacting inner edges 51e of the side guiding parts 51 are formed so as to become 30 degrees or lower. The outer edge 52a of the front side guiding part 52 is formed so as to become salient forward.
