Below, the structure of the characteristic of present embodiment is described.

Fig. 2 is the figure of opening state midway of the lid of presentation graphs 1.Fig. 3 is the figure of state that the expression lid is positioned at the open end of Fig. 1.Fig. 4 is the major part amplification view of Fig. 1, and is expression along with the figure of the variation of the position relationship of the rear portion externally mounted part of exterior of the rear portion, articulated section of the opening of lid and lid.

Such as Fig. 2～shown in Figure 4, when opening lid 3, along with the opening of lid 3, exterior 21 ground that the rear portion externally mounted part 30 of lid 3 is covered with the rear portion, articulated section move.Exterior 21 of this rear portion, articulated section becomes and approaches and along the circular-arc shape of heaving that is of the motion track L of the rear portion externally mounted part 30 of lid 3.Thus, when lid 3 is open, because the gap S(between the rear portion externally mounted part 30 of lid 3 and rear portion, articulated section exterior 21 is with reference to Fig. 4) be retained as constant distance, sandwiched this gap S so can prevent from pointing.In addition, this gap S is configured to point the distance that is not sandwiched certainly.

For relatively, the electric cooker of in the past constructing is shown in Fig. 5～Fig. 8 here.Such as Fig. 5～shown in Figure 8, in structure in the past, along with the rotation of lid 3A, the rear portion externally mounted part 30A of lid 3A and the rear portion, articulated section temporarily enlarge (with reference to Fig. 6, Fig. 8) with gap SA exterior 21A, diminishing afterwards (with reference to Fig. 7, Fig. 8), is the structure of easily clamping finger.

Turn back to the explanation of Fig. 1.In rice cooker body 2, below articulated section 4, be formed with spatial portion 11, dispose control substrate 12 at this spatial portion 11.In the present example, owing to exterior 21 of articulated section 4 formed be the circular-arc shape of heaving, even be extended to this to the rear positions of major general's spatial portion 11 and heave the identical depth position of the top 21a of part, also can not make the maximize volume of ground expansion space sections 11 of rice cooker body 2.In the example of Fig. 1, the rear positions that constitutes spatial portion 11 is positioned at the position of slightly leaning on the rear than the top 21a that heaves part.And, the externally mounted part upper surface 11a of spatial portion 11 formed the inclined plane that tilts towards the below.This is because as shown in Figure 3 and Figure 4, be positioned under the state of open end the gap S1 between the rear portion externally mounted part 30 of guaranteeing significantly lid 3 and the externally mounted part upper surface 11a of spatial portion 11, and prevent from pointing and sandwiched among the S1 of gap at lid 3.In addition, according to same reason, the rear portion externally mounted part 30 of lid 3 is formed, the lower surface 31(of the rear portion externally mounted part 30 of the lid 3 when lid 3 is positioned at the state of open end is with reference to Fig. 4) become the inclined plane that tilts towards the top.
