Meanwhile, the gear 4321 is engaged and fixed with the rack 4322, so that the reliability and the synchronism between the connecting part 431 and the transmission part 432 are improved. Meanwhile, an opening is formed in the partition plate 23, and the limiting plate 4313 penetrates through the partition plate 23 and is connected to the recess 4312 in the side region M and the rack 4322 in the middle region N, respectively.
