BEST MODE FOR CARRYING OUT THE INVENTION Embodiments of the present invention will be described below with reference to the accompanying drawings. 1 and 2 relate to the first embodiment, and FIG. 1 shows an automatic bread maker 11 and a bread case 12 housed therein. The bread case 12 is opened and closed by opening a lid 14 of a predetermined storage portion 13 of the automatic bread maker 11.

The bread case 12 is the bread case body 1
5 and handles 17 attached to the flanges 16 on both sides of the opening.

As shown in FIGS. 2 (a) and 2 (b), the structure of the mounting portion of the handle 17 is such that a square mounting hole 18 is formed in the flange 16, and the bearing member 19 is formed in the mounting hole 18 portion. Is installed.

The bearing member 19 is formed by bending one metal plate, and has a width narrowed by a bearing portion 21 which is bent in an inverted U shape as a whole and engaging step portions 22 and 22 on both sides of its lower end. The mounting portions 23 are formed by inserting the mounting portions 23 into the mounting holes 18, and are bent at the lower surface of the flange 16 as shown in FIG. 2B.

A pair of shaft supporting pieces 25, 25 are minute and opposed to two parallel sides of one side surface of the bearing portion 21 (the outer side 24 of the flange 16 in the case shown in the figure). Butt with a gap. A shaft insertion portion 26 is formed by the inverted U-shaped arc portion of the bearing portion 21 and the shaft support pieces 25, 25.

In the bearing member 19, the mounting portion 23 is inserted into the mounting hole 18 from the upper surface side of the flange 16, the engaging step portions 22 are engaged with both sides of the mounting hole 18, and at the lower surface of the flange 16. The mounting portion 23 is mounted by bending it outward (see FIG. 2 (b)). As a result, the bearing member 19 is attached to the flange 16 in a state in which the inverted U-shaped bearing portion 21 and the shaft support piece 25 forming the shaft insertion portion 26 are projected onto the flange 16.

The bent tip portion 27 of the handle 17 is shown in FIG.
As shown by the two-dot chain line in (a), the bearing member 19 is inserted into the shaft insertion portion 26 from the inside, and the outer peripheral surface of the bearing portion 21 has an inverted U shape and two shaft support pieces 25, 25. Supported by. Therefore, the bent tip portion 27 of the handle 17 is
As shown in FIG. 2B, a gap having a height h ₁ is generated between the flange 16 and the surface thereof, and the flange 16 does not come into contact with the surface.

The bending of the mounting portion 23 can be easily performed by an operator using a hand tool. This is because the bearing portion 21 has a width that is sufficiently wider than the thickness of the material, so that the load supporting area of the pan case body 15 is sufficiently large, and therefore the material may be relatively thin. .

In the first embodiment described above, the bearing member 19 is inserted into the mounting hole 18 from above the flange 16, but the second embodiment shown in FIGS. 3 (a) and 3 (b) is , The bearing member 19 from below the flange 16 in the mounting hole 1
It is a format to be inserted in the No. 8. That is, in this case, horizontal protrusions 28 are formed on both outer surfaces of the inverted U-shaped bearing portion 21 by stamping, and the mounting portion 23 is slightly inwardly moved to the mounting hole 18 from the lower surface side of the flange 16. After the insertion and the insertion, the mounting portion 23 is returned to the original state by the elasticity of the material, the projection 28 is engaged with the upper surface of the mounting hole 18, and then the mounting portion 23 is bent to be mounted.

When the bent tip portion 27 of the handle 17 is inserted into the shaft insertion portion 26, a height h is formed between the bent tip portion 27 and the surface of the flange 16.
The gap is generated as in the case described above.

The third embodiment shown in FIGS. 4A to 4D is also similar to the second embodiment in that the bearing member 19 is inserted into the mounting hole 18 from the lower surface side of the flange 16. However, in this case, the elasticity of the material of the bearing member 19 is positively utilized. That is, the mounting hole 18 in this case is provided with engaging portions 29, 29 at both ends of the two sides of the flange 16 in the width direction. Further, the inverted U-shaped bearing portion 21 of the bearing member 19 is slightly open on both sides in the natural state before the attachment, as compared with the state after the attachment. In addition, the bearing portion 21
Engagement recesses 31, 31 are formed on both sides of the bent portion between the lower end of the and the mounting portion 23.

Incidentally, the point that the shaft support pieces 25, 25 are provided is the same as in each of the above-described embodiments, and the mounting portion 23 is bent outward in advance.

The above-mentioned bearing member 19 is inserted from below the mounting hole 18 while the operator presses the mounting portions 23 on both sides inwardly with a fingertip to narrow the interval between the lower ends of the bearing portions 21, and the engagement thereof is made. The recess 31 is elastically engaged with the engaging portion 29 of the mounting hole 18. The bent tip portion 27 of the handle 17 is inserted and supported by the shaft insertion portion 26 as in the case of each of the above-described embodiments.

You may form the fitting recessed part 32 as shown in FIG. The fitting recess 32 is formed such that the lower end thereof has substantially the same height as the upper end of the shaft supporting piece 25 or a slightly higher height h ₂ (see FIG. 4D).

When the fitting recess 32 is provided as described above,
In the upright state, the handle 17 is in a state of hitting the top of the inverted U-shaped bearing portion 21 (see FIG. 4C), and when a force is applied to either the left or right side, a part of the handle 17 falls in the direction of falling. Elastically fits into the fitting recess 32 and stops in that position (see the chain double-dashed line in FIG. 4B). For this reason,
As shown in FIG. 5, a required gap h ₃ is formed between the handle 17 and the flange 16, and the user can insert the grip or the like held by his / her fingertip or hand into the gap h ₃ to grip the handle 17. it can.

[0026]

As described above, according to the present invention, the shaft insertion portion is formed by the arcuate portion of the top of the inverted U-shaped bearing portion and the shaft supporting piece facing the shaft insertion portion, and the bending tip portion of the handle is attached to the shaft insertion portion. Since the handle is inserted, the handle does not come into contact with the flange of the pan case body, and therefore the fluororesin coating layer of the flange is not damaged.

Further, since the above-mentioned inverted U-shaped bearing portion is formed by bending a metal plate having a required width, the required load resistance can be obtained by the width even when the material is thin. Since the material is easy to bend, installation work can be done with only simple hand tools. Further, since the bearing member is elastically engaged to be mounted in the mounting hole of the flange, the workability is improved because the material is easily bent, and the bearing member can be downsized.

Since the inverted U-shaped bearing portion is provided with the fitting concave portion, a gap h ₃ is formed between the tilted handle and the flange, so that the handle can be easily grasped.
