【従来の技術】従来分割型でガイド以外は金属で出来た
もの、分割型でほとんどプラスチックで出来たものが有
った。2. Description of the Related Art Conventionally, there were a split type, which was made of metal except for the guide, and a split type, which was mostly made of plastic.
【０００３】[0003]
【発明が解決しようとする課題】これらには次のような
欠点があった。 （イ）分割型でガイド以外は金属でできたものはレバー
が一番上に有るためプッシュボタンとの位置合わせのた
めレバーを曲げ加工をし加重のかかる位置をずらしてい
た。このため動作時にレバーに大きな曲げ応力が掛かり
強度的に弱かったり、変形が大きかった。また分割のた
めのラッチも極性キーより外に飛び出ていたために取り
扱い時に壊れやすかった。 （ロ）分割型でピラスチックで出来たものはプラスチッ
クが複雑な形状になり成型性が悪くまた強度的に弱かっ
た。本発明はこれらの欠点を除くためになされたもので
ある。These have the following drawbacks. (B) In the split type, which is made of metal other than the guide, the lever is located at the top, so the lever was bent to align it with the push button, and the position where the weight was applied was shifted. For this reason, a large bending stress was applied to the lever during operation, resulting in weak strength and large deformation. Also, the latch for splitting was sticking out of the polar key, so it was easy to break during handling. (B) The split type made of pilastic had a complicated plastic shape and poor moldability and weak strength. The present invention has been made to eliminate these drawbacks.

みで左右のプッシュロッドに対応した製品ができる。(A) Since the metal fitting holding latch provided on the header is within the range of the main body, it is difficult to break even if it falls during molding or handling, and the total length of the header is short, which shortens the stroke when combined with the mechanism section. . (B) The metal lever rotation shaft fits with the metal lever bearing portion to rotate, and thus has high durability and can withstand a high load. Further, since there is only the drawer plate rising portion in the center of the drawer plate, the strength is strong and the influence of abrasion powder and the like from the bearing portion is small. (C) Since the lever is between the upper cover and the drawer plate, the stress applied to the load receiving part for the drawer plate, the drawer plate rising part, the load receiving part for the push rod, etc. is small, so a thin material can be used. Can be used. (D) The push rod can be attached just by having a small push rod guide in the guide, and if the shape of the push rod is completely symmetrical, the push rod can be easily attached on either the left or right side, and only one mold is available. The product corresponding to the left and right push rods can be made.
