上記目的を達成するためになされた請求項１の発明に係るドアロック装置は、車両のドアに固定されるよう適合される支持ケースと、支持ケース内に配置され、ロック位置とアンロック位置との間を回動してドアをロック及びアンロックするよう適合されるロックレバーと、支持ケースに設けられたストッパ部と、ロックレバーに設けられたストッパ当接部と、ロックレバーをロック位置とアンロック位置との中間位置から遠ざけるように付勢し、その付勢力によって、ロックレバーのストッパ当接部を支持ケースのストッパ部にロック位置又はアンロック位置で押し付ける弾性部材と、を備え、支持ケースは、ロックレバーを回動可能に支持しかつ弾性部材を弾性変形可能に支持した第１ケース分割体と、ストッパ部を有した第２ケース分割体とを、ロックレバーの回動軸方向で合体することにより構成され、第１ケース分割体に設けられ、第１ケース分割体と第２ケース分割体が分離した状態で、弾性部材と協働してロックレバーの回動を規制し、ロックレバーが弾性部材から付勢力を受けずかつストッパ当接部が回動軸方向でストッパ部と対向する待機位置にロックレバーを保持する待機位置保持部と、第１ケース分割体と第２ケース分割体とに設けられ、合体過程の第１ケース分割体と第２ケース分割体との横ずれを規制するように互いに係合して、ストッパ当接部とストッパ部とが回動軸方向で対向した状態に維持する合体ガイドと、ストッパ部及びストッパ当接部の何れか一方に設けられて、第１ケース分割体及び第２ケース分割体の合体過程で他方に摺接してロックレバーを弾性部材に押し付ける側に回動させて待機位置からロック位置又はアンロック位置に移動するストッパガイドとを備えたところに特徴を有する。 In order to achieve the above object, a door lock device according to the invention of claim 1 is provided with a support case adapted to be fixed to a door of a vehicle , and disposed in the support case, and includes a lock position and an unlock position. A lock lever adapted to lock and unlock the door by rotating between, a stopper portion provided in the support case, a stopper abutting portion provided in the lock lever, and the lock lever in the lock position An elastic member that urges away from an intermediate position with respect to the unlock position, and presses the stopper contact portion of the lock lever against the stopper portion of the support case at the lock position or the unlock position by the urging force. The case includes a first case divided body that rotatably supports the lock lever and elastically deforms the elastic member, and a second case having a stopper portion. A body, configured by coalesce rotation axis direction of the lock lever, provided on the first casing divided body, in a state where the first case divided member and the second case divided body is separated, an elastic member cooperating with The standby position holding portion that restricts the rotation of the lock lever, holds the lock lever at a standby position where the lock lever does not receive a biasing force from the elastic member, and the stopper contact portion faces the stopper portion in the rotation axis direction. And a stopper abutting portion that is provided on the first case divided body and the second case divided body and engages with each other so as to restrict lateral displacement between the first case divided body and the second case divided body in the joining process. combined guide and, provided on either the stopper portion and the stopper abutting portion, coalescence process of the first case split body and the second case divided body and the stopper portion is kept in a state of being opposed in the rotation axis direction And slide to the other to lock Bar from the standby position is rotated to the side of pressing the elastic member in place and a stopper guide which moves to the locked position or unlocked position with the features.

請求項２の発明は、請求項１に記載のドアロック装置において、ストッパ部及びストッパ当接部の何れか一方に設けられたストッパガイドが他方に摺接する前に、合体ガイドが互いに係合するところに特徴を有する。 The invention of claim 2 is the door lock device according to claim 1, the stopper portion and the stopper guide provided on either one of the stopper abutting portion before sliding contact with the other, coalescence guide are engaged with each other However, it has characteristics.

第１ケース分割体にロックレバーを組み付けるとき、ロックレバーは、弾性部材から付勢力を受けない待機位置に組み付けられ、弾性部材と待機位置保持部とによってその待機位置に保持される。また、第１ケース分割体と第２ケース分割体との合体過程では、それらに設けられた合体ガイドの係合によって第１ケース分割体と第２ケース分割体との横ずれが規制され、待機位置に保持されたロックレバーのストッパ当接部と第２ケース分割体が有するストッパ部とが、ロックレバーの回動軸方向で対向した状態で維持される。そして、第１ケース分割体と第２ケース分割体との合体過程で、ストッパ部及びストッパ当接部の何れか一方に設けられたストッパガイドが他方に摺接してロックレバーを弾性部材に押し付ける側に回動させる。つまり、第１ケース分割体に対して待機位置で保持されていたロックレバーが、第１ケース分割体と第２ケース分割体との合体過程で待機位置からロック位置又はアンロック位置へと移動する。 When the lock lever is assembled to the first case divided body, the lock lever is assembled at the standby position where the urging force is not received from the elastic member, and is held at the standby position by the elastic member and the standby position holding portion . Further, in the process of combining the first case divided body and the second case divided body, the lateral displacement between the first case divided body and the second case divided body is restricted by the engagement of the combined guide provided thereon, and the standby position. The stopper abutting portion of the lock lever held by the stopper and the stopper portion of the second case divided body are maintained in a state of facing each other in the rotation axis direction of the lock lever. The coalescence process of the first case divided member and the second case split body, the side to press the stopper portion and the stopper guide provided on either one of the stopper abutting portion is in sliding contact with the other lock lever to the resilient member Turn to. That is, the lock lever held at the standby position with respect to the first case divided body moves from the standby position to the locked position or the unlocked position in the process of combining the first case divided body and the second case divided body. .

図１４及び図１５には、アクティブレバー２５を、アンロック位置よりも中間位置から遠ざかった待機位置（「アンロック位置側の待機位置」という）にして、アクティブレバー回動軸５３に組み付けたときの状態が示されている。同図に示すように、アンロック位置側の待機位置では、アクティブレバー２５の円弧孔２５Ｓのうち第２外面１１Ｂに向かって左側の端部が、ホイール回転軸５４の側面に当接するか又は近接配置される。また、図１４に示すように、節度ピン２５Ｐは、節度バネ２７における１対の摺接突部２７Ａ，２７Ａの頂部よりもコイル部側に遊嵌されている。そして、ホイール回転軸５４と節度バネ２７とが協働してアクティブレバー２５の回動を規制しており、アクティブレバー２５はアンロック位置側の待機位置に保持される。なお、ホイール回転軸５４は、本発明の「待機位置保持部」に相当する。 14 and 15, when the active lever 25 is assembled to the active lever rotating shaft 53 in a standby position (referred to as a “standby position on the unlock position side”) farther from the intermediate position than the unlock position. The state of is shown. As shown in the figure, at the standby position on the unlock position side, the left end of the arc hole 25S of the active lever 25 toward the second outer surface 11B comes into contact with or close to the side surface of the wheel rotation shaft 54. Be placed. As shown in FIG. 14, the moderation pin 25 </ b> P is loosely fitted closer to the coil portion than the tops of the pair of sliding contact projections 27 </ b> A and 27 </ b> A in the moderation spring 27. The wheel rotation shaft 54 and the moderation spring 27 cooperate to regulate the rotation of the active lever 25, and the active lever 25 is held at the standby position on the unlock position side. The wheel rotation shaft 54 corresponds to the “standby position holding portion ” of the present invention.
