DOOR LOCK RELEASE MECHANISM

To provide a door lock release mechanism that can easily and inexpensively change an automobile with a door lock device having no wire locking part in a release lever into an automobile with a rear door opening and closing device of a manual type.SOLUTION: An automobile 11, with a door lock device 13 having no locking part 45 of a wire 19 in a release lever 17 since an attacker part 40 is joined to a lever extension member 42 via a bolt-nut structure 41, can easily and inexpensively be changed into one with a rear door opening and closing device 18 of a manual type. Since the lever shaft is a disc rivet shaft 38 that also serves as the rotation shaft of the lever extension member 42 and a shaft hole 43a of the lever extension member 42 is a straight hole in line contact with a peripheral side surface of a head 38a of the disc rivet shaft 38 constantly and annularly, the looseness of the bolt-nut structure 41 caused by "clearance fit" during the rotation of the release lever 17 can be eliminated.SELECTED DRAWING: Figure 1 【課題】解除レバーにワイヤ掛止部がないドアロック装置付きの自動車を、簡単かつ低コストに手動式の後扉開閉装置付きの自動車に改装できるドアロック解除機構を提供する。【解決手段】アタッカ部４０にレバー延長部材４２をボルトナット構造体４１により連結したため、解除レバー１７にワイヤ１９の掛止部４５が無いドアロック装置１３付きの自動車１１を、簡単で低コストに手動式の後扉開閉装置１８付きのものに改装できる。また、レバー軸をレバー延長部材４２の回動軸を兼ねた皿リベット軸３８とし、レバー延長部材４２の軸孔４３ａを、皿リベット軸３８の頭部３８ａの周側面と常時円環状に線接触するストレート孔としたため、解除レバー１７の回動時、"すきまばめ"を原因としたボルトナット構造体４１の緩みを解消できる。【選択図】図１
