Claims Analysis
Total Claims: 16
Claim 1
Independent Claim
100 words
A vehicular lamp lens, wherein at least two lens members are integrated together, the lens members each having a front surface, the front surfaces being joined together at a boundary between the lens members, wherein: the front surface of at least one of the lens members is displaced in the rearward direction as the front surface becomes closer to the boundary between the at least one lens member and another one of the lens members to which the at least one lens member is integrated, and the displaced front surface of the at least one lens member forms an indentation.
Claim 2
Dependent Claim
100 words
A vehicular lamp lens, wherein at least two lens members are integrated together, the lens members each having a front surface, the front surfaces being joined together at a boundary between the lens members, wherein: the front surface of at least one of the lens members is displaced in the rearward direction as the front surface becomes closer to the boundary between the at least one lens member and another one of the lens members to which the at least one lens member is integrated, and the displaced front surface of the at least one lens member forms an indentation.
Claim 3
Dependent Claim
58 words
A vehicular lamp lens, comprising: a first lens member; and a second lens member integrated with the first lens member and forming a boundary therebetween; wherein the front surface of the boundary side of said first lens member is displaced in the rearward direction as it becomes closer to the boundary so as to form a first indentation.
Claim 4
Dependent Claim
58 words
A vehicular lamp lens, comprising: a first lens member; and a second lens member integrated with the first lens member and forming a boundary therebetween; wherein the front surface of the boundary side of said first lens member is displaced in the rearward direction as it becomes closer to the boundary so as to form a first indentation.
Claim 5
Dependent Claim
41 words
The vehicular lamp lens of claim 2 , wherein the front surface of the boundary side of said second lens member is displaced in the rearward direction as it becomes closer to the boundary so as to form a second indentation.
Claim 6
Dependent Claim
24 words
The vehicular lamp lens of claim 3 , wherein the first and second indentations are each an inclined surface, together forming a V-shaped groove.
Claim 7
Dependent Claim
19 words
The vehicular lamp lens of claim 3 , wherein the first and second indentations are each a bowed surface.
Claim 8
Dependent Claim
16 words
The vehicular lamp lens of claim 2 , wherein the first indentation is an inclined surface.
Claim 9
Dependent Claim
16 words
The vehicular lamp lens of claim 2 , wherein the first indentation is a bowed surface.
Claim 10
Dependent Claim
107 words
A vehicular lamp lens, wherein at least two lens members are integrated together, the lens members each having a front surface, the front surfaces being joined together at a boundary between the lens members, wherein: the front surface of at least one of the lens members is displaced in the rearward direction as the front surface becomes closer to the boundary between the at least one lens member and another one of the lens members to which the at least one lens member is integrated, and the lens members that are integrated together each have at least one welding leg for integrating the lens members by welding.
Claim 11
Dependent Claim
107 words
A vehicular lamp lens, wherein at least two lens members are integrated together, the lens members each having a front surface, the front surfaces being joined together at a boundary between the lens members, wherein: the front surface of at least one of the lens members is displaced in the rearward direction as the front surface becomes closer to the boundary between the at least one lens member and another one of the lens members to which the at least one lens member is integrated, and the lens members that are integrated together each have at least one welding leg for integrating the lens members by welding.
Claim 12
Dependent Claim
32 words
The vehicular lamp lens of claim 8 , wherein at least one of the lens members has a joint leg and the at least one welding leg extends from said joint leg.
Claim 13
Dependent Claim

The vehicular lamp lens of claim 9 , wherein the front surface of at least one of said lens members displaced in the rearward direction forms an indentation at the boundary between said lens members.
Claim 14
Dependent Claim
22 words
The vehicular lamp lens of claim 8 , wherein each of said welding legs extends toward and abuts an opposing lens member.
Claim 15
Dependent Claim
28 words
The vehicular lamp lens of claim 11 , wherein the welding legs for one lens member are spaced apart from the welding legs for an opposing lens member.
Claim 16
Dependent Claim
41 words
The vehicular lamp lens of claim 12 , wherein said front surface of said at least one lens member that is displaced in the rearward direction is a front surface of the welding legs for said at least one lens member.
