Of course, the through bar 47 is not limited to one. Similarly, the slot 48 and the side of the opening 49 connected to the welding zone 412 can form a vertical surface on the outer side of the welding zone 412, increasing the bonding surface in the vertical direction, and the welding strength can be further enhanced if no groove is provided. Holes 48 or openings 49 are also possible. In addition, the opening 49 is used to increase the welding strength because the opening 49 is located at the position where the corresponding first contact portion 44 is depressed.
