PROBLEM TO BE SOLVED: To prevent generation of latch noise upon opening of a mail box, etc.SOLUTION: A character combination lock comprises: a cylindrical main body part 1; a dial operation board 4 which rotates on a dial center shaft 3; a plurality of rotors 5, 6 rotated to locking or unlocking position by operation on the dial operation board; a latch member 7; and a locking member 8. The latch member consists of: a main latch 20 abutting to a locking piece 8a of the locking member; and a sub latch 30 which is connected to the main latch via a movable shaft in a hung manner and being detachable from a stopper member 40 supported on the main latch or the cylindrical main body part in a fixed manner. Upon unlocking, when the cylindrical main body part is moved to an opening direction, a projecting outer end part of the sub latch comes in contact with a receiving piece 71 on a fixed member side so that the sub latch is rotated in a direction toward a back end surface side of the cylindrical main body part. An engaging arm of the sub latch is engaged with a fingertip shaped engaging part 41 of the stopper member in a surface contacting state in a corresponding manner to rotation of the sub latch so that the sub latch is held by the stopper member.
【課題】郵便箱等の扉開時におけるラッチ音発生の防止。【解決手段】筒状本体部１と、ダイヤル中心軸３を中心にして回転するダイヤル操作盤４と、ダイヤル操作盤の操作によって施錠又は解錠位置へと回転する複数個の回転子５，６と、ラッチ部材７と、ロック部材８を備えた文字合せ錠に於いて、ラッチ部材は、ロック部材のロック片８ａと当接するメインラッチ２０と、メインラッチに可動軸を介してぶら下がり状に接続すると共に、メインラッチ或いは筒状本体部に固定的に支持されたストッパー部材４０と係脱するサブラッチ３０とから成り、解錠時、筒状本体部が開く方向へ移動するときには、サブラッチは、その突出外端部が固定部材側の受け片７１に当たるとこにより筒状本体部の後端面側方向へと回転し、サブラッチの回転量に対応してその係合腕がストッパー部材の指先状係止部分４１に面接触状態に係入して該ストッパー部材に保持される文字合せ錠。【選択図】図１
