0 is a portion where the sheet member 1 is placed before the key buttons 3 . . . are formed. The first cavity 10 and the second cavity 11 communicate with each other at part A. This portion A becomes a fused portion between the peripheral edge of the opening 2 of the sheet member 1 and the flange portion 4 of the key button 3. The second cavities 11 for molding the key buttons 3 are formed independently so as not to communicate with each other. In this case, in order to avoid shrinkage after the key button 3 is molded, it is necessary to mold the key button 3 as evenly and thinly as possible. In order to make the second cavity 11 thin as described above, it is necessary to form the mold 9 into a projecting shape by forming one side B of the second cavity 11. Therefore, the portion corresponding to one side B of the key button 3 is attached to the sheet member l.
If the key button 3 is covered, it will not be possible to make the key button 3 thinner. An opening 2... is formed in the sheet member 1, and this opening 2...
This is why key button 3 is made to correspond to key button 3. Further, the third cavity 12 forming the holding member 6 is formed to communicate with each other by ribs in the right angle direction (not shown), and its lower end surface is connected to the first cavity 10.
It will be communicated to. In this case, since the seat member 1 is placed in the cavity 10, it does not communicate with the $2 cavities 11 for molding the key buttons 3. The upper mold 9 consists of two upper and lower molds 13 and 14, and runners 15 are formed on opposing surfaces of these molds. This runner 1
Reference numeral 5 denotes a channel through which the molding resin flows, into which the molding resin is injected from an injection port 16 formed in the upper mold 13, and a key button gate 17 formed in the lower mold 14.・
