The object of the present invention is to provide a mounting structure for a lamp cleaner.

[Means for solving problems]

The mounting structure of the automotive headlamp cleaner according to the present invention has a nozzle holder with a cleaning water injection nozzle on the top protruding from the lower end of the nozzle case, and the lower surface of the nozzle case abuts a part of the mounting part on the vehicle side. , in an automobile headlamp cleaner in which a cylindrical shaft part continuous with the nozzle holder is fixed by protruding to the lower surface side thereof, the clamp holding protrusion formed on a part of the cylindrical shaft part is elastically inserted between the lower surface of the bumper. The gist of the present invention is to constitute an insertion guide means for guiding the insertion between the plate-shaped clamp members toward the cylindrical shaft portion and guiding them to the upper surface of the clamp presser protrusion.

That is, the pair of clamp holding protrusions protruding from the sides of the cylindrical shaft extending from the nozzle case each have a baffle plate-like guiding inclined part continuous with the insertion side end of the plate-shaped clamp member. The plate-shaped clamping member is made of an elastic material having an appropriate elastic force, and has the above-mentioned nozzle on each of the upper and lower pieces, which are curved in the shape of a "U" or "U" shape on the side surface. The insertion guide means is formed by forming a bifurcated structure that straddles the cylindrical shaft portion of the holder, and forming an introduction guide portion bent and inclined in the direction of the upper piece at the tip of the lower piece.

[Effect]

According to the above configuration, the cylindrical shaft part is inserted into the mounting hole from the top surface of the bumper, and with the bottom surface of the nozzle case in contact with the top surface of the bumper, the top piece is attached to the bottom surface of the bumper, and the top piece is attached to the clamp presser protrusion side. When the plate-shaped clamp member is press-fitted so that the lower piece is positioned and the two pronged structures sandwich the cylinder shaft, the elasticity of the plate-shaped clamp member will push the cylinder shaft through the clamp holding protrusion. is pulled under the bumper, and its elastic tensile force firmly presses and fixes the nozzle case to the top surface of the bumper. When press-fitting this plate-shaped strip-like clamp member, the inclined introduction guide part at the tip of the lower piece is scooped up by the guide inclined part, and at the same time as it is inserted into the upper surface side of the clamp holding protrusion, the two-pronged structure naturally joins the cylindrical shaft. Since it is inserted into the desired device position accurately, it is possible to grope at the time of assembly.
