Abstract:

To fix a rod lens to a casing and prevent loosening of the rod lens and to facilitate assembly work, the present invention includes: a casing (2) that has a bottom wall (21) and a pair of side walls (22, 23) extending upward from the bottom wall (21); a rod-shaped lens (4) provided above an LED substrate (3) and along the length direction inside the casing (2); and fixing mechanisms (5) for fixing the lens (4) to the pair of side walls (22, 23). Each fixing mechanism (5) includes: an upward-facing surface (51a) provided along the length direction on the inner surface of the side wall (22 or 23); a downward-facing surface (52a) provided along the length direction on a side peripheral surface of the lens (4); a concave groove (53) provided above the upward-facing surface (51a) and along the length direction in the inner surface of the side wall (22 or 23); and an elastic body (54) that fits into the concave groove (53) and contacts the side peripheral surface of the lens (4) in a state where the downward-facing surface (52a) is in contact with the upward-facing surface (51a).
