[Diagram 5] FIG. 4 is a side view of the holes and pins shown in FIG. 3. DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS

[0010] Hereinafter, an embodiment of the present invention will be described with reference to the drawings. Fig. 1 is a perspective view of an instrument device according to an embodiment of the present invention. In the following description, for convenience, the direction along the long side of a rectangle that is the shape of a case or the like is defined as the left-right direction, and the direction along the short side of the rectangle is defined as the up-down direction. The left-right direction corresponds to the width direction of a vehicle when the instrument device is installed in the vehicle. The up-down direction corresponds to the height direction of the vehicle when the instrument device is installed in the vehicle.

[0011] 1 is provided, for example, on an instrument panel in front of the driver's seat of a vehicle. The instrument device 1 includes a case 2 and a dial 3. In addition to the case 2 and the dial 3, a bezel (design component), a faceplate, etc. may also be provided.

[0012] Case 2 is a one-piece resin molded product having a substantially rectangular outer shape. Case 2 is formed with recesses and the like capable of accommodating electronic components and the like mounted on a substrate (not shown). On the substrate, for example, a driving motor for the pointer of the indicating instrument, light-emitting elements for warning displays on dial 3, and driving circuits for driving them are mounted.

[0013] Case 2 is provided with holes 21 and 22 through which, for example, the rotation axis of the hands passes. Holes 21 and 22 are provided at a distance from each other along the longitudinal direction of case 2. Case 2 is also provided with pins 23 and 24 at the longitudinal ends of case 2, which are inserted into notches 331 and 341, which will be described later. Case 2 is also provided with pins 25 and 26, which are inserted into holes 35 and 36, which will be described later. Pins 25 and 26 are provided at a distance from each other along the longitudinal direction of case 2. Pins 23, 24, 25, and 26 are provided so as to protrude from case 2 in the direction in which dial 3 is placed.

[0014] 1 shows the state immediately before the dial 3 is attached to the case 2, with a slight gap between the case 2 and the dial 3. Therefore, the pins 23 and 24 are not exposed from the dial 3. Furthermore, the pins 25 and 26 do not protrude from the dial 3.

[0015] The dial 3 is a member consisting of a substantially rectangular plate body, and is a member on which various designs such as scales, patterns, symbols, characters, decorations, etc. are drawn according to information related to the vehicle in which the instrument device 1 is mounted. For example, a speedometer dial design, a rotary system dial design, etc. are drawn on the dial 3 by a well-known method such as printing.

[0016] The dial 3 has holes 31 and 32 formed at positions corresponding to the holes 21 and 22. The holes 31 and 32 have protrusions formed therein for fixing the dial to the case 2 (see FIG. 2 for the protrusion 311 of the hole 31). The protrusions 311 and the like are inserted into, for example, a double-supported beam-shaped fixing portion formed on the case 2, thereby fixing the dial 3 so that it does not float up.

[0017] The dial 3 has protrusions 33, 34 formed at both longitudinal ends of the dial 3. A notch 331 is formed at the top of the protrusion 33. Similarly, a notch 341 is formed at the top of the protrusion 34.

[0018] The dial 3 has a hole 35 formed in the lower left portion and a hole 36 formed in the lower right portion. The holes 35 and 36 are provided in positions different from the notches 331 and 341 as shown in FIG.

[0019] FIG. 2 is an enlarged view of the protruding portion 33. The protruding portion 33 has slopes 33a and 33b and a peak 33c. The slopes 33a and 33b form a mountain shape at the left end of the dial 3 with gentle slopes. In FIG. 2, the slopes 33a and 33b are substantially straight, but they may be curved, such as in an arc shape. However, it is preferable that the corners connecting the slopes 33a and 33b and the peak 33c are not sharp. In the shape of FIG. 2, the protruding portion 33 is not sharp, so that the pin 23 is not likely to get caught during work and the finger F of the worker can easily hold it.

[0020] Top 33 is flat, and has cutout 331 cut toward the right end. The length (depth) of cutout 331 may be long enough to insert pin 23. Protrusion 34 has the same structure as protrusion 33.

[0021] FIG. 3 is an enlarged view of hole 35. Pin 25 is inserted into hole 35. Hole 35 is formed as an elongated hole that allows dial 3 to slide upward with pin 25 inserted. At this time, pin 25 appears to slide from top to bottom inside hole 35 (from left to right in FIG. 3). This is because convex portion 331 is inserted from the underside of the fixed portion by sliding dial 3 upward in the figure. Hole 36 has the same configuration as hole 35.

[0022] Fig. 4 is a view from the longitudinal direction when the case 2 and the dial 3 are assembled. As shown in the upper part of Fig. 4, the worker holds the protrusions 33, 34 and assembles them by overlapping them on the case 2. Then, when the protrusions 33, 34 are released, the pins 23, 24 enter the notches 331, 341 (lower part of Fig. 4).

[0023] With the case 2 and dial 3 assembled in this way, it is possible to check whether the dial 3 is floating by observing the protruding state of the pins 25 and 26 (Figure 5). Figure 5 shows the correctly assembled state. If the dial 3 is floating, the amount of protrusion of the pin 25 will be small.

[0024] According to this embodiment, the instrument device 1 includes a case 2 and a dial 3 attached to the case 2. A protrusion 33 is formed at a longitudinal end of the dial 3, and a top 33c of the protrusion 33 is flat, and a notch 331 for fixing the dial 3 to the case is formed in the top 33c.

[0025] By configuring the instrument device 1 as described above, the longitudinal end of the dial 3 is made into a convex portion 33, and a notch 331 for fixing the dial 3 to the case 2 is formed in the flat top portion 33c, eliminating the need to provide a sharp protruding piece. This makes it easy for an operator to handle and improves the ease of assembly of the dial 3.

[0026] Furthermore, since the protrusion 33 is formed in a mountain shape and the notch 331 is formed at the top 33c, the protrusion 33 is not sharp, and it is easy for the worker to hold and assemble the protrusion 33. Furthermore, since the slopes 33a and 33b are substantially straight, the pin 23 does not get caught on the protrusion 33 or the like during assembly, improving workability. Furthermore, since the slopes 33a and 33b are unlikely to catch on the pin 23, the pin 23 can be guided along the slopes 33a and 33b to the notch 331, further improving workability.

[0027] Furthermore, the case 2 is provided with a pin 25 that stands upright from the case 2, and the dial 3 is provided with a hole 35 through which the pin 25 can enter, so that the number of positions for the dial 3 can be increased in addition to the notches 331 and 341. This allows the dial 3 to be positioned with high precision. Also, it is easy to determine whether the dial is floating based on the amount of protrusion of the pin 25.

[0028] Furthermore, hole 35 is shaped like an elongated hole that allows pin 25 to slide inside hole 35, making it possible to accommodate assembly work in which protrusions 331, etc. are slid. Also, the position of pin 25 inside hole 35 makes it easy to check whether dial 2 is bent or not, and to check whether it is assembled correctly.

[0029] The present invention is not limited to the above-described embodiment. In other words, a person skilled in the art can implement the present invention by modifying it in various ways in accordance with conventional knowledge without departing from the gist of the present invention. As long as the instrument device of the present invention is still provided even after such modification, it is of course included in the scope of the present invention. [Explanation of symbols]
