  As shown in FIGS. 6A to 6C, the engaged portions 26a and 26b of the present embodiment are formed inside the housing from the peripheral wall portion 2c. Here, the distance r between the engaged portion 26a and the engaged portion 26b of the present embodiment is, for example, from the outer end of the engaging claw 36a1 shown in FIG. 4B to the engaging claw 36b1. The distance p is greater than or equal to the distance p before the expansion to the outer end and less than or equal to the distance q after the expansion from the outer end of the engagement claw 36a1 to the outer end of the engagement claw 36b1 shown in FIG. Designed to be

  Further, in the engaged portions 26a and 26b of this embodiment, the distance u from the edge of the peripheral wall portion 2c shown in FIG. 6B to the engaged surfaces of the engaged portions 26a and 26b is as shown in FIG. The distance between the inner surface 3B of the rear casing member 3 after the expansion shown and the engaging claws 36a1 and 36b1 is less than t.

  By designing in this way, when the front housing member 2 and the back housing member 3 are combined, the engaging portions 36a and 36b before the expansion can be joined without any resistance. 26b and the engaging portions 36a and 36b and the engaged portions 26a and 26b can be engaged with each other by expansion.

  Further, it is assumed that the height v of the engaged portions 26 a and 26 b is designed to be shorter than the diameter m of the through hole portion 36. Further, it is assumed that the distance w from the arrangement position 2C of the display panel 4 to the peripheral wall portion 2c is designed to be equal to or larger than the diameter m of the through hole portion 36. As described above, in this embodiment, the distance w from the arrangement position 2C of the display panel 4 to the peripheral wall 2c can be reduced to the diameter m of the through hole 36.

  In this embodiment, slide prevention walls 26a1 and 26b1 are formed to prevent the engagement portions 36a and 36b engaged with the distal ends of the engaged portions 26a and 26b from sliding in the inside of the housing. An example is shown. Further, the distance x from the peripheral wall portion 2c to the slide prevention walls 26a1 and 26b1 is assumed to be not less than the width n of the engaging portions 36a and 36b shown in FIG. Thus, by providing the anti-slide wall at the tip of the engaged portions 26a, 26b, the engaged portions 36a, 36b can be prevented from sliding toward the inside of the housing.

  Next, the engagement structure in the present embodiment will be described with reference to FIGS. FIG. 7 shows an engagement structure between the front casing member 2 and the rear casing member 3. FIG. 7A is a cross-sectional view showing a state before the engagement portions 36a and 36b are expanded, that is, before engagement. FIG. 7B is a view after the engagement portions 36a and 36b are expanded, It is sectional drawing which shows the state which engaged. This sectional view is a sectional view showing the engaging portions 36a and 36b seen from the A section in FIG. 4B and the engaged portions 26a and 26b seen from the C section in FIG. 6B, respectively. It is.

  FIG. 8 is a perspective view showing an engagement structure between the front housing member 2 and the back housing member 3. FIG. 8A is a perspective view showing a state before the engagement portions 36a and 36b are expanded, that is, before the engagement, and FIG. 8B is a view after the engagement portions 36a and 36b are expanded, that is, It is a perspective view which shows the state which engaged. 7 and 8 show the engagement structure of the engaging portions 36a and 36b and the engaged portions 26a and 26b for the sake of simplicity of explanation, the structure of other engaging portions and engaged portions is shown. Is the same.

  As shown in FIGS. 7A and 7B and FIGS. 8A and 8B, the engagement structure of this embodiment is associated with the fitting engagement member 309 fitted into the through-hole portion 36. The joint portions 36a and 36b are expanded and engaged with the engaged portions 26a and 26b, respectively.

  As described above with reference to FIGS. 4 to 6, the distance r between the engaged portion 26a and the engaged portion 26b of the present embodiment is the spread between the outer end portions of the engaging claws 36a1 and the engaging claws 36b1. It is designed to be equal to or greater than the previous distance p and equal to or less than the distance q after expansion between the outer ends of the engaging claws 36a1 and 36b1.

  Therefore, when the front-side housing member 2 and the rear-side housing member 3 are combined, the engaging portions 36a and 36b before expansion are inserted between the engaged portion 26a and the engaged portion 26b without resistance. In addition, the engaging portions 36a and 36b and the engaged portions 26a and 26b can be engaged by expanding. When the front housing member 2 and the rear housing member 3 are separated, the engaging portions 36a and 36b are in a state before being expanded by pulling out the fitting engaging member 309 from the through hole portion 36. The engagement can be easily released.

  As described above, in the engagement structure of the present embodiment, when the front housing member 2 and the rear housing member 3 are attached and detached, the screw member is not required to be screwed in or removed, so that it can be easily attached and detached. Work can be performed.

  In the present embodiment, the engaging portions 36 a and 36 b expand in a direction along the side surface of the display panel 4. Therefore, in the front housing member 2 and the rear housing member 3, the width of the engaging portion in the direction orthogonal to the side surface of the display panel 4 can be reduced to the diameter m of the through hole 36 at a minimum. Thereby, in the present embodiment, the space of the engaging portions provided in the front housing member 2 and the back housing member 3 can be reduced, and the display device 1 can be downsized.

  Further, in this embodiment, the fitting engagement member 309 is fitted into the through-hole portion 36 so that the engagement portions 36a and 36b are expanded and engaged with the engaged portions 26a and 26b. Although it demonstrated, not only this but the structure which can expand engagement part 36a, 36b and can be engaged with the to-be-engaged part 26a, 26b should just be sufficient.

  The present invention is not limited to the above-described embodiment as it is, and can be embodied by modifying the constituent elements without departing from the scope of the invention in the implementation stage. In addition, various inventions can be formed by appropriately combining a plurality of components disclosed in the embodiment.
