That is, the control position display device includes a housing upper 21, an indicator plate 22 attached to the housing upper 21, a cover slide 24 that slides together with the rod 23, and a lamp housing part 25 that are integrally formed. It consists of a four-piece structure including a housing lower 26. The indicator plate 22 is welded to the housing upper 21, and the cover slide 24 is held slidably in a sandwiched state between the housing upper 21 and the housing lower 26.
27 is a lamp.

In the conventional control position display device structure as described above, the housing consists of a separate structure of the housing upper 21 and the housing lower 26, which increases the number of parts and requires more man-hours for assembly, as well as waste of materials and increased costs. There was the problem of inviting

In order to eliminate or alleviate this problem, the control position display device is constructed by integrally forming a lamp housing portion consisting of a recess for accommodating the lamp into a one-piece housing, and an indicator plate is placed in the opening of the lamp housing portion. It is desirable to form an indicator plate guide section that serves as a mounting seat and a presser section that presses down the indicator plate from above, attach the indicator plate to the indicator plate guide section, and press both ends of the indicator with the presser section.

With this configuration, the housing is changed from the conventional two-part structure of the housing top and housing lower to a one-part structure, reducing the number of parts, resulting in material savings, weight reduction, cost reduction, Assemblability can be improved.

Problems to be Solved by the Invention However, the control position display device described above has a structure in which the indicator plate attached to the housing is supported on the lower side by the indicator plate guide part and the upper sides of both ends are held down by the presser parts. Since the indicator plate was sharp, there was a risk that the center portion of the indicator plate would float up from the indicator plate guide portion and come off from the housing.

To prevent this, it is effective to press the center of the indicator plate, but forming the holding means near the center of the indicator plate of the housing causes another problem of poor appearance. .

An object of the present invention is to prevent the indicator plate from coming off from the housing without damaging the external appearance in a control position display device in which the housing is constructed of a one-piece structure and the indicator plate is mounted from above the housing.

Means for Solving the Problems The control position display device for an automatic transmission for an automobile according to the present invention, which meets this objective, has a lamp housing portion consisting of a concave portion for accommodating a lamp integrally formed in a housing consisting of one part. Indicator plate guide parts that support the indicator plate from below are formed on both sides in the width direction of the opening of the lamp housing part, and presser parts that press the indicator plate from above are formed at both longitudinal ends of the opening, and the presser parts An indicator plate having a projection projecting downward and a hole or a depression formed at both ends in the longitudinal direction is assembled by engaging the projection in the hole or depression and pressing both ends of the indicator plate in the longitudinal direction with a presser part. It consists of something attached to the guide part.

Function In the control position display device configured as described above, the conventional housing upper and housing lower as shown in FIG. 7 are replaced with one housing in which the lamp housing part is integrally molded. There is. The indicator plate can be easily assembled to the housing by bending the indicator plate using its elasticity, fitting the hole or recess of the indicator plate into the protrusion of the holding part of the housing, and attaching it to the indicator plate guide part. It will be held in

Both ends of the indicator plate attached to the housing are engaged with the protrusions, so even if the center part of the indicator plate tries to lift upward, the protrusions prevent the indicator plate from lifting and deforming, so that the indicator plate does not move away from the housing. will be prevented from leaving. Furthermore, since no floating prevention means is formed on the outer surface near the center of the indicator plate, the indicator plate has a good appearance.
