Description

  The present invention relates to a mounting structure in a vehicle.

  In a vehicle, for example, in a vehicular lamp, a light guide member as an attachment member is attached to an attachment location.

  As a mounting structure for the mounting, a so-called arrowhead-shaped mounting protrusion provided with a key-shaped portion that gradually increases the width dimension from the tip is formed on the light guide member (mounting member), and the mounting protrusion is mounted at the mounting location. There is one that prevents the mounting protrusion from coming off from the mounting hole by passing it through the hole. With this mounting structure, it is possible to prevent falling off with a simple mounting operation, but since the mounting protrusion can be pushed further into the mounting hole, the relative movement between the light guide member (mounting member) and the mounting location Therefore, there is room for improvement from the viewpoint of improving the mounting strength.

  In view of this, in the mounting structure, it is conceivable that the fixing protrusion is provided with a predetermined interval on the mounting protrusion, and the peripheral edge of the mounting hole is sandwiched between the fixing protrusion and the key-shaped part. However, with such a configuration, in the mold for forming the light guide member (mounting member) having the mounting protrusion, it is necessary to provide a slide core around the key-shaped part and the fixed projecting part. In this case, the manufacturing cost of the light guide member (mounting member) is increased.

  For this reason, in the attachment structure, what attaches a light guide member (attachment member) to a to-be-attached location via a clip is considered (for example, refer to patent documents 1). In this conventional mounting structure, the mounting protrusion having the key-shaped portion and the fixing protrusion is formed on the clip that is separate from the light guide member (mounting member). Therefore, the slide core is formed on the mold for forming the clip. Without providing, a key-like part and a fixed projection part can be formed on the attachment projection.

  However, since the conventional mounting structure uses a clip that is separate from the light guide member (mounting member), it is necessary to prepare a separate mold for the light guide member (mounting member) and the clip, and the mounting process. Therefore, there is room for improvement from the viewpoint of simplifying the mounting operation and suppressing an increase in manufacturing cost.

  The present invention has been made in view of the above circumstances, and an object of the present invention is to provide an attachment structure that can be easily attached and can improve attachment strength while suppressing an increase in manufacturing cost.

  The attachment structure according to claim 1 includes an attachment protrusion provided on an attachment member in a vehicle, and a frame-like portion provided at a place to be attached in the vehicle. A mounting plate-like portion that protrudes in one direction and forms a mounting surface including the first direction; and at least three fixing protrusions that protrude from the mounting surface in a second direction orthogonal to the mounting surface; In the mounting surface, the protruding end-side arrangement row extending in the third direction orthogonal to the first direction and the second direction on the protruding end side of the mounting plate-shaped portion, and the frame-shaped portion viewed in the first direction An attachment member side arrangement row extending in the third direction at a position displaced from the protruding end side arrangement row to the attachment member side by a thickness dimension, and at least one of the fixed protrusions projects Provided on the end side arrangement row and the rest is the mounting member side Together provided on 置列, and which are located alternately between the third said at different positions in the direction as the protruding end side arranged rows on the mounting member side arranged rows on.
