Description

  The present invention relates to a protective film attached to a wheel for rust prevention.

  Conventionally, in order to prevent the occurrence of rust on the brake disc rotor inside the wheel before delivery of the vehicle, it has been widely performed to attach a resin rust prevention cover to the wheel. However, since such a resin rust-proof cover needs to be produced according to the size and shape of the wheel, the manufacturing cost is relatively high.

Therefore, in place of the above-described rust-proof cover, a protective film is known that is bonded to the outer surface of the wheel by adhesion in order to realize lower cost. For example, Patent Document 1 discloses a protective film that is attached to an outer surface of a disk surface of a wheel, and has a cut formed for releasing pressure on the protective film surface. Patent Document 2 discloses a peeling device that peels off a release paper attached to the adhesive surface of a protective film before attaching such a protective film to a wheel.

  However, in the protective film as described above, when the release paper is peeled off and attached to the wheel, the adhesive is exposed at a portion not in contact with the wheel. Therefore, there is a problem that foreign matters such as dust adhere to the portion where the adhesive is exposed, and there is room for further improvement.

  This invention is made | formed in view of such a condition, The place made into the objective is to provide the protective film with few adhesion of a foreign material, when it affixes on a wheel.

  In order to solve the above-described problems, a protective film according to an aspect of the present invention is a protective film attached to a disk surface of a wheel, the film, an adhesive portion provided on one surface of the film, and a protective film And a peeling member that covers the adhesive portion when not in use and peels off during use. The peeling member includes a circular first cut line that divides the first portion of the bonding portion that is attached to a wheel rim so as to be exposed, and an inner region of the first cut line. And a plurality of second cut lines that are radially formed up to the first cut line and that divide the second region of the adhesive portion that is attached to the spokes of the wheel so as to be exposed.

  According to this aspect, the peeling member that covers the annular first region by the first cut line can be securely attached to the rim of the wheel by peeling off the peeling member. Moreover, it becomes possible to selectively peel off the peeling member that covers the second region corresponding to the wheel spokes by the second cut line. In other words, the part located in the opening part between spokes among the protective films affixed on the disk surface of the wheel can be in a state where the peeling member is not peeled off. As a result, the area of the protective film adhesive layer that remains exposed without directly adhering to the rim or spoke on the wheel disk surface is reduced.

  The first region may have a width substantially equal to a height of a rim to be attached. This prevents the first region from being exposed by protruding from the rim. Here, the height of the rim can be, for example, the difference between the inner diameter and the outer diameter of the rim as viewed from the disk surface side.

  The second cut line may be formed in a range of 6 to 30 lines. Thereby, it becomes possible to selectively peel off the peeling member that covers the second region according to the number and interval of the spokes.

  The peeling member may be provided so that a knob portion for facilitating peeling from the film continues to the cut line. Thereby, the workability | operativity at the time of selectively peeling the peeling member which covers the area | region divided by the cut line improves.

  According to the present invention, it is possible to reduce adhesion of foreign matters when pasted on a wheel.

  Hereinafter, the best mode for carrying out the present invention will be described in detail with reference to the drawings. In the description of the drawings, the same elements are denoted by the same reference numerals, and repeated descriptions are omitted as appropriate.
