  • one end 16E1 of the inner lens 16 is placed in the space formed by the main body 121 and first side wall 122 of the outer lens 12.
  • one end 16E1 includes one end of the main body 161 of the inner lens 16 and the first side wall 162 extending from that end.

  • the inner lens 16 is positioned within the outer lens 12 with one end 16E1 and the other end 16E2 positioned close to both ends of the outer lens 12.
  • the outer lens 12 is fixed to the lamp body 11 with the light source unit 13, light guide 14, and reflector 15 placed between the outer lens 12 and the lamp body 11. In this way, the vehicle lamp 10 is manufactured.
  • the inner lens 16 is formed so that the longitudinal dimension (outer dimension) L1 of the inner lens 16 is longer than the minimum longitudinal dimension L2 of the opening 124 of the outer lens 12. For this reason, as illustrated in FIG. 6, even if the inner lens 16 is moved parallel to the outer lens 12 in a state where the inner lens 16 is directly opposed to the outer lens 12 (with the longitudinal direction of the inner lens 16 parallel to the longitudinal direction of the outer lens 12), the inner lens 16 interferes with the outer lens 12, and the inner lens 16 cannot be positioned inside the outer lens 12.

  • the inner lens 16 is bent until the apparent length of the inner lens 16 becomes shorter than the minimum longitudinal dimension L2 of the opening 124 of the outer lens 12, and in this state, the inner lens 16 is placed inside the outer lens 12. Therefore, it is possible to attach the inner lens 16 to the outer lens 12 without one end 16E1 and the other end 16E2 of the inner lens 16 interfering with the first side wall portion 122 and the second side wall portion 123 of the outer lens 12.
  • the inner lens 16 is inserted from the opening 124 of the outer lens 12, rather than from above or below the outer lens 12, even if the outer lens 12 further has a third side wall portion 127 and a fourth side wall portion 128 as shown in Figures 3 and 4, the inner lens 16 can be attached to the outer lens 12 without interfering with the third side wall portion 127 or the fourth side wall portion 128 of the outer lens 12.
  • the longitudinal dimension L1 of the inner lens 16 is 0.8 m or more. In this way, by having the inner lens 16 have a certain degree of length, the inner lens 16 can be easily flexed.
  • the outer lens 12 has a first root portion 125 and a second root portion 126.
  • the first root portion 125 is a portion where the first side wall portion 122 rises from the main body portion 121.

  • the second distance D2 is the distance between the second root portion 126 and the first side wall portion 122.
  • the outer lens 12 has a symmetrical shape, so the first distance D1 and the second distance D2 are the same length.
  • the dimension L1 of the inner lens 16 is shorter than the first distance D1
  • the inner lens 16 is rotated around the one end 16E1 as the center of rotation
  • the other end 16E2 of the inner lens 16 can be inserted into the outer lens 12 without interfering with the second side wall portion 123 of the outer lens 12, even if the inner lens 16 is not bent.
  • the inner lens 16 is bent, so that even when a longer inner lens 16 is used, the other end 16E2 of the inner lens 16 does not interfere with the second side wall portion 123 of the outer lens 12, and the inner lens 16 can be attached to the outer lens 12.
  • first side wall portion 122 and the second side wall portion 123 of the outer lens 12 are inclined inward in the vehicle width direction by the same angle with respect to the fore-and-aft direction of the lamp.
  • first side wall portion 122 and the second side wall portion 123 may be inclined at different angles from each other, or either one of the first side wall portion 122 and the second side wall portion 123 may extend parallel to the fore-and-aft direction of the lamp.
  • the first side wall portion 122 and the second side wall portion 123 of the outer lens 12 extend so that all parts approach each other.
  • the first side wall portion 122 and the second side wall portion 123 may be configured so that only parts of them extend so that they approach each other.
  • the first side wall portion 122 and the second side wall portion 123 extend so that they approach each other from both ends of the main body portion 121 to position P, and extend parallel to each other from position P.
  • the minimum longitudinal dimension L2 of the opening of the outer lens 12 is the longitudinal dimension between the tip of the first side wall portion 122 and the tip of the second side wall portion 123.
  • the first distance D1 is the distance between the first root portion 125 and the position P of the second side wall portion 123.
  • the second distance D2 is the distance between the second root portion 126 and the position P of the first side wall portion 122.
  • the attachment method shown in Figures 5A to 5D involves bending the inner lens 16.
  • the inner lens 16 may be attached to the outer lens 12 while bending the outer lens 12, or while bending both the inner lens 16 and the outer lens 12.
  • Figures 8A to 8D show a method of attaching an inner lens 16 to an outer lens 12 while deflecting both the inner lens 16 and the outer lens 12.
  • the outer lens 12 is bent in a direction in which the longitudinal dimension of the opening 124 of the outer lens 12 increases.
  • the outer lens 12 is set in a fixing device (not shown) in a state in which both ends of the outer lens 12 are pushed downward to bend the outer lens 12.

  • one end 16E1 of the inner lens 16 is inserted from above into the opening 124 of the outer lens 12, and one end 16E1 of the inner lens 16 is placed in the space formed by the main body portion 121 and the first side wall portion 122 of the outer lens 12.
  • the other end 16E2 in the longitudinal direction of the inner lens 16 is inserted into the outer lens 12. Specifically, with at least a portion of one end 16E1 of the inner lens 16 abutting against the first side wall portion 122 of the outer lens 12, while bending the inner lens 16 upward, the other end 16E2 of the inner lens 16 is placed in the space formed by the main body portion 121 and the second side wall portion 123 of the outer lens 12.
  • the amount by which the inner lens 16 is bent may be less than the amount by which the inner lens 16 is bent in the mounting method of Figures 5A to 5D. Because the longitudinal dimension of the opening 124 of the outer lens 12 is increased by bending the outer lens 12, even if the amount by which the inner lens 16 is bent is small, the other end 16E2 of the inner lens 16 is inserted into the outer lens 12 without interfering with the second side wall portion 123 of the outer lens 12.
  • the inner lens 16 is returned to its original shape by pressing it in the direction opposite to the bending direction (downward in this example).
  • the downward force applied to both ends of the outer lens 12 is also released to return the outer lens 12 to its original shape.
  • FIG. 8A if the longitudinal dimension of the opening 124 of the outer lens 12 becomes sufficiently large by bending the outer lens 12, the other end 16E2 of the inner lens 16 may be inserted into the outer lens 12 without bending the inner lens 16 in FIG. 8B.
  • the inner lens 16 has a first side wall portion 162 and a second side wall portion 163.
  • the inner lens 16 may have a shape consisting of only the main body portion 161, without the first side wall portion 162 and the second side wall portion 163.
  • the vehicle lamp 10 is described as a lamp installed at the rear of the vehicle, but it may also be applied to a lamp installed at the front or side of the vehicle.
  • the vehicle lamp 10 uses the light guide 14 and the reflector 15 as optical components that guide the light emitted from the light source unit 13 to the inner lens 16.
  • the vehicle lamp 10 may use other optical components to guide the light emitted from the light source unit 13 to the inner lens 16.
