Summary:To perform automatic locking only with an operation to return a handle lever to the original position when a door is closed.SOLUTION: In this lock handle H, a guide part 210c is formed on a peripheral wall part of a reception hole 210 of an operation shaft 21 while communicating with a through hole 2120 to guide a dead bolt 5 to a lock groove 104 in a sliding manner. The dead bolt 5 is formed so that it can engage with a cam part 41 of a joint member 4 in the guide part 210c only in one direction where the dead bolt 5 separates from the lock groove 104 to retract into the reception hole 210. The dead bolt 5 is also disposed in the guide part 210c, with a coil spring 53 interposed between an end, opposite to the lock groove 104, of the guide part 210c and an end of the dead bolt 5.SELECTED DRAWING: Figure 2 【課題】扉を閉める際に、ハンドルレバーを元に戻す操作のみで、オートロックする。【解決手段】このロックハンドルＨでは、操作軸２１の受孔２１０の周壁部に透孔２１２０に連通してデッドボルト５をロック溝１０４に摺動案内するガイド部２１０ｃを形成され、デッドボルト５はガイド部２１０ｃ内でジョイント部材４のカム部４１にデットボルト５がロック溝１０４から離脱し受孔２１０内に引き込まれる一方向にのみ係合可能に形成されるとともに、ガイド部２１０ｃのロック溝１０４とは反対側の端部とデッドボルト５の端部との間にコイルスプリング５３を介してガイド部２１０ｃ内に配置される。【選択図】図２
