Abstract

A waterproof case for an in-vehicle camera includes a front case part and a rear case part, and houses imaging means such as the imaging device therein. A packing member is set between the front case part and the rear case part, and waterproofs and seals the space therebetween. A water-stop wall part is protrudingly formed on a flange part which is an attaching portion of the rear case part at a peripheral of the packing member. A concave part, into which the water-stop wall part can be fitted, is formed on an opening peripheral part which is an attaching portion of the front case part.

1 . A waterproof case for an in-vehicle camera comprising: 
 a first case part;    a second case part which forms a case body with the first case part so as to house imaging means;    a packing member set between the first case part and the second case part; and    a water preventing section provided between the first case part and the second case part,    wherein the packing member waterproofs and seals the space between the first case part and the second case part, and    the water preventing section prevents the packing member from being exposed to water outside.    
   
   
       2 . The waterproof case for an in-vehicle camera according to  claim 1 , 
 wherein the water preventing section comprises:    a water-stop wall part protrudingly formed on an attaching portion of the first case part at an outer peripheral of the packing member; and    a concave part formed on an attaching portion of the second case part,    wherein the water-stop wall part can be fitted in the concave part.    
   
   
       3 . The waterproof case for an in-vehicle camera according to  claim 2 , 
 wherein the water-stop wall part is fitted to the concave part such that a positional relation of the first case part and the second case part is maintained constant.    
   
   
       4 . The waterproof case for an in-vehicle camera according to  claim 2 , 
 wherein the first case part includes a lens holding cylinder part which holds a imaging lens of the in-vehicle camera.    
   
   
       5 . The waterproof case for an in-vehicle camera according to  claim 2 , 
 wherein the second case part includes a lens holding cylinder part which holds a imaging lens of the in-vehicle camera.    
   
   
       6 . The waterproof case for an in-vehicle camera according to  claim 1 , 
 wherein the water preventing section is provided at an outer peripheral of the packing member.    
   
   
       7 . The waterproof case for an in-vehicle camera according to  claim 1 , 
 wherein a packing housing groove is formed on one of the first case part or the second case part,    further wherein the packing member is housed in the packing housing groove such that the packing member protrudes from the packing housing groove.    
   
   
       8 . The waterproof case for an in-vehicle camera according to  claim 1 , 
 wherein the first case part and the second case part are fixed together with a screw.    
   
   
       9 . The waterproof case for an in-vehicle camera according to  claim 2 , 
 wherein the water-stop wall part is intermittently projected from the attaching portion of the first case part.
