Description

DETAILED DESCRIPTION OF THE INVENTION (Industrial field of application) The present invention relates to a dial plate fixing structure for an on-vehicle instrument, and more particularly, when fixing the dial plate by engaging an engaging hole and an engaging claw, The present invention relates to a dial plate fixing structure for a vehicle-mounted instrument having a strong engagement.

(Prior Art) The look-back plate is a partition plate for keeping the instruments in the meter and the like housed in the case invisible from the outside, and is fixed to the case as shown in FIGS. 4 to 6, for example. (Japanese Utility Model Publication No. 60-49417). According to the figure, the engagement frames 22 that are raised in steps are provided on the upper side and the lower side of the face portion of the case 20 on which the dial plate 21 is fixed, and the engaging claws 23 provided on the dial plate 21 are provided. Engagement hole 24 of the engagement frame 22
The dial plate 21 is fixed to the case 20 by engaging with.

Here, a rib 25 is provided along the length direction on the rear surface of the engaging claw 23 on the base end side (see FIGS. 5A to 5C), and the rib 25 allows the dial plate 21 to be turned over. Is positioned, and rattling between the engagement hole 24 and the engagement claw 23 is prevented.

According to the structure for fixing the dial plate, the ribs 25 prevent the dial plate 21 from being displaced in the vertical direction, and one or two of the plurality of engaging claws 23 are engaged with respect to the displacement in the horizontal direction. nail
At 23, the width dimension c and the dimension d of the engaging hole 24 are set tight so that the engagement between the engaging claw 23 and the engaging hole 24 is strengthened and prevented (see FIG. 6). ).

(Problems to be solved by the invention) However, the surface of the rib 25 contacting the inner surface of the engagement hole 24 is flat, and the rib 25 of one or two of the plurality of engagement claws 23 is engaged. Even if it is pressed against the inner surface of the fitting hole 24, it is not always sufficient to prevent displacement in the left-right direction, and when twisting acts on the meter housed in the case 20, the engagement between the engagement claw 23 and the engagement hole 24 is large. In the place where the joint is not strong, the dial plate 21 is displaced from the case 20 in the left-right direction and the appearance is inferior.
Further, there is a possibility that abnormal noise may be generated due to vibration when the vehicle is running.

This invention was made in order to solve the above-mentioned problems of the prior art. The purpose is to prevent the dial plate from shifting with respect to the case, and to generate abnormal noise due to vibrations when the vehicle is running. It is an object of the present invention to provide a facing plate fixing structure for an on-vehicle instrument that does not have the risk of

(Means for Solving the Problems) In order to achieve the above object, in the present invention, an engaging hole is provided in either the case or the dial plate, and an engaging claw is provided in the other, and the engaging claw is engaged. In a dial plate fixing structure for an on-vehicle instrument in which the dial plate is fixed to the case by engaging with the hole, a rib having an edge cross section is provided along the longitudinal direction of the rear surface of the engaging claw on the base end side. The rib is configured so as to bite slightly into the inner surface of the engaging hole.

(Operation) When the engaging claw is engaged with the engaging hole, the rib slightly digs into the inner surface of the engaging hole to strengthen the engagement between the engaging claw and the engaging hole.

Embodiment An embodiment of the present invention will be described below with reference to the drawings.

FIG. 1 shows an on-vehicle instrument to which the fixing structure of the present invention is applied. Reference numeral 1 in the drawing is a case accommodating meters, and the dial plate 4 is fixed to the front side of the case 1 through the engagement of the engagement hole 2 and the engagement claw 3, but it is important here. This is that ribs 5 having an edge cross-section are formed along the longitudinal direction on the rear surface of the engaging claw 3 on the base end side (see FIGS. 2A and 2B).

The cross-sectional edge shape means a shape having a sharp tip like a blade. The dimension a of the engaging claw 3 including the rib 5 on the base end side is set to be slightly larger than the dimension b of the engaging hole 2 (see FIG. 3). Therefore, when the engaging claw 3 is inserted into the engaging hole 2, a part of the rib 5 bites into the inner surface of the engaging hole 2 and structural friction is generated in addition to friction due to pressure contact, and the engaging hole 2 is A stronger engagement can be obtained as compared with a rib having a flat portion in contact with the inner surface (see FIGS. 5B and 5C). That is, by providing the engaging claws 3 having such ribs 5 in one or two places, it is possible to prevent not only the vertical direction but also the horizontal direction shift at all the fixed points, and also due to the shift. It is possible to prevent rattling that occurs.

Here, one end side of the rib 5 is obliquely cut in order to reduce the resistance when the rib 5 engages with the engagement hole 2 and to ensure smooth engagement (see FIG. 3), The obliquely cut inclined portion 5a is also formed to have an edge sectional shape (see FIGS. 2A and 2B).

Reference numeral 6 in FIG. 1 denotes a front glass, which is fixed to the dial plate 4, but the fixing structure described above can be applied to this fixing structure. Further, 7 is a dial of the meter.

The engagement hole 2 is formed on a stepped engagement frame 8 provided on the front side of the case 1, and the engagement frame 8 is formed on the upper side and the lower side of the front side of the case 1, respectively. This is the same as the conventional one.

Further, at the tip of the engaging claw 3, there is provided a claw 9 having a right-angled wall 9a rising at a right angle and a slope 9b gently inclined downward from the upper end of the right-angled wall 9a. Is also the same as the conventional one in that the right angle wall 9a projects from the engagement hole 2 and the right-angled wall 9a is hooked on the end surface of the engagement frame 8 to maintain the engaged state.

(Effect of the Invention) As described above, according to the present invention, a rib having a cross-sectional edge shape that slightly digs into the inner surface of the engaging hole is provided along the longitudinal direction of the rear surface of the engaging claw on the base end side. In addition, the dial plate is not displaced with respect to the case, and there is no fear that abnormal noise will be generated due to vibration when the vehicle is running.
