Operation button keeping construction

Abstract

The invention provides an operation button keeping construction capable of improving positioning precision of a resetting button member under the state of sub assembly, and good assembly operability. A front cover button hole (14a) roughly in an ovate shape in a front view, a V-shaped groove part (18) formed at the lower edge of the inner circumferential surface is provided with a pair of inclining surfaces (18a, 18b) spaced apart from the opening center (NP) of the front cover button hole and symmetrically configured at left and right two sides on the inner circumferential surfaces. Each inclining angle (Alpha 1, Alpha 2) of the inclining surfaces are provided with the same angle (Alpha 1=Alpha 2), the inclining surfaces incline toward left and right opposite sides and are spaced apart via the vertical line of the opening center, and are formed via a linear extension along the tangential line to the circular inner circumferential surface of the front cover button hole. Each abutting point (15d, 15d) at the surrounding of approximately 45 degrees at left and right from the external side circumferential lower side of the resetting button component (15) are respectively in an elastic contact with the inclining surfaces in a mode that a counter force toward the center is generated at the left and right two points.

Description

technical field [0001] The present invention mainly relates to an operation button holding structure used in vehicles such as automobiles, and particularly relates to an operation button holding structure in which an operation front end of a reset button protrudes from a transparent front cover member toward the interior of a vehicle interior. Background technique [0002] In the past, such as Figure 11 with Figure 12 As shown, as the operation button holding structure of the vehicle display device, there is known an operation button holding structure provided on the instrument cluster device 1 located in front of the driver's seat in the vehicle compartment R (for example, refer to Patent Document 1, 2). [0003] First, the configuration of the combination meter device 1 will be described. In the combination meter device 1 , a flat plate-shaped circuit board 2 made of epoxy resin is provided in a resin meter case 4 constituting a housing. [0004] On this circuit board ...

Problems solved by technology

[0027] In such a case, to Figure 11 When the outer cover member 11 is mounted in the direction indicated by the blank arrow in the figure, even if the guide surface 11b is formed in the reset button opening 11a, it is difficult for the front end 12a to pass through the reset button opening 11a, resulting in poor workability.

[0028] In addition, if the front end portion 12a is barely inserted into the reset button opening 11a and installed in the reset button opening 11a, the reset button member 12 may be deformed or damaged.

[0029] Furthermore, due to the pressing force applied from such a reset button member 12, the push button switch 6 provided on the circuit board 2 may be pressed in an uneven direction by the pressing end portion 12b of the reset button member 12 to be damaged.
