Is prevented, the operation failure of the operation switch 54 is eliminated, and the feel and operability of the operation switch 54 can be improved. Moreover, since the improvement of the usability, the operational feeling and the appearance is achieved by the fitting of the positioning recess 58 and the positioning boss 62, it is an effect that can be obtained reliably and stably without variation. Can be planned.

Further, since the positioning recess 58 and the positioning boss 62 are tapered, and the outer diameter of the tip of the positioning boss 62 is made smaller than the inner diameter of the positioning recess 58 entrance, the control device 42 and the operating member
The mounting work of the 45 can be performed easily, and defects such as breakage and deformation of the control device 42 and the operation member 45 due to a mistake in the mounting work can be prevented.

Further, as shown in FIG. 5, by forming the positioning recess 58 and the positioning boss 62 with a plurality of tapers, the thickness of the root of the positioning boss 62 is reduced, and the positioning recess is formed.
Since the positioning boss 62 and the positioning boss 62 can be fitted with a slight undercut, the control device 42 and the operating member
It is possible to prevent sinking of the operation member 45 and stabilize the dimensions while preventing the displacement of the operation member 45.
The mounting strength of the LCD holding member 55 can be improved.

In this embodiment, the positioning recess 58 and the positioning boss 62
Although a taper is formed on the LCD holding member 55 and the push button portion 57 is provided integrally with the LCD holding member 55, the present invention is not limited to the taper or the push button portion 57. Can be prevented, and the LED 52 and the LCD 53 can be easily seen to improve usability and appearance.

As is clear from the description of the above embodiment, the bread maker of the present invention is provided with the concave and convex portions which are inserted and fitted into the LCD holding member and the operating member, so that the position of the substrate is shifted by an external force. Or, even if the LED or LCD legs are bent, due to the fitting of the uneven parts when attaching the control device to the operating member,
Since the LEC and the LCD are arranged at the predetermined position of the operation member 45 via the LCD holding member, the LEC and the LCD can be reliably and stably provided without variation, and the usability and the appearance can be improved.

In addition, by integrally providing the push button for pressing the operation switch on the LCD holding member, the displacement of the push button together with the LED and LCD can be prevented, so that operation failure of the operation switch is eliminated and operability and operability are improved. It can be improved.

In addition, by forming the uneven portion in a tapered shape,
Similarly to the above, it is possible to improve the workability of mounting the control device to the operation member while preventing the displacement of the control device and the operation member, and to prevent the failure such as damage or deformation of the component due to a mistake in the mounting operation. You can do it.

Further, by forming the uneven portion with a plurality of tapers, it is possible to prevent displacement of the operation member and the operation member as described above, prevent sinking of the operation member and stabilize the dimensions, and maintain the operation member and the LCD. The mounting strength of the member can be improved.

Therefore, the present invention has a tremendous industrial value that can significantly improve merchantability including qualities such as usability, operability, appearance, strength, and the like, and eliminate defects by improving assembly workability.
