以上説明したシフト装置10では、図2~図4に示されるように、ノブ12が「P」位置に配置された場合(ノブ12のシフト位置が「P」位置であることをシフトセンサが検出した場合)で、かつ、ブレーキが操作されない際には、シフトロック機構46において、制御装置の制御により、モータ26が正駆動されて、伝達機構28(ウォームギア30、中間ギア36及びノブ駆動ギア18)を介して、カム構成体52が矢印E側へ向けて回転される。また、カム構成体52が矢印E側へ向けて回転されると、ロックバー54のカム部係合部54Bがカム部50の解除面50Bに当接している状態から当該カム部50の第1切欠部50A1内に配置された状態となる。そして、ロックバー54のカム部係合部54Bがカム部50の第1切欠部50A1内に配置された状態では、ロックバー54が図示しないスプリングの付勢力によってノブ本体14側へ移動されて、ロックバー54の規制部54Cがノブ本体14のロックバー被係合部14Aに挿入される。これにより、ノブ12(ノブ本体14)の回転がロック(規制)されて、ノブ12の「P」位置から「R」位置、「N」位置及び「D」位置への回転がロック(規制)される。
In the shift device 10 described above, as shown in FIGS. 2 to 4, when the knob 12 is disposed at the “P” position (the shift sensor detects that the shift position of the knob 12 is the “P” position) When the brake is not operated, the motor 26 is positively driven in the shift lock mechanism 46 under the control of the control device, and the transmission mechanism 28 (the worm gear 30, the intermediate gear 36, and the knob drive gear 18). ), The cam assembly 52 is rotated toward the arrow E side. Further, when the cam structure 52 is rotated toward the arrow E, the cam portion engaging portion 54B of the lock bar 54 is in contact with the release surface 50B of the cam portion 50, and the first cam portion 50 It will be in the state arrange | positioned in notch 50A1. Then, in a state where the cam portion engaging portion 54B of the lock bar 54 is disposed in the first notch portion 50A1 of the cam portion 50, the lock bar 54 is moved toward the knob main body 14 by the biasing force of a spring not shown. The restricting portion 54C of the lock bar 54 is inserted into the lock bar engaged portion 14A of the knob main body 14. Thereby, the rotation of the knob 12 (knob main body 14) is locked (restricted), and the rotation from the "P" position of the knob 12 to the "R" position, the "N" position and the "D" position is locked (restricted). Be done.
一方、ノブ12が「P」位置に配置された場合に、ブレーキが操作された際には、シフトロック機構46において、制御装置の制御により、モータ26が逆駆動されて、伝達機構28を介して、カム構成体52が矢印F側へ向けて回転される。また、カム構成体52が矢印F側へ向けて回転されると、ロックバー54のカム部係合部54Bがカム部50の第1切欠部50A1内に配置された状態から当該カム部50の解除面50Bに当接している状態となる。そして、ロックバー54のカム部係合部54Bがカム部50の第1切欠部50A1内に配置された状態からカム部50の解除面50Bに当接している状態とされることで、ロックバー54がノブ本体14と離間する方向へ向けて移動される。その結果、ロックバー54の規制部54Cが、ノブ本体14のロックバー被係合部14A内から離脱される。これにより、ノブ12(ノブ本体14)の回転のロックが解除されて、ノブ12が「P」位置から「R」位置、「N」位置及び「D」位置に回転可能にされる。
On the other hand, when the knob 12 is disposed at the “P” position, when the brake is operated, the motor 26 is reversely driven in the shift lock mechanism 46 by the control of the control device, and the transmission mechanism 28 Thus, the cam assembly 52 is rotated toward the arrow F side. Further, when the cam structure 52 is rotated toward the arrow F side, the cam portion engaging portion 54B of the lock bar 54 is disposed in the first cutout portion 50A1 of the cam portion 50, and the cam portion 50 It will be in the state which is in contact with release side 50B. The cam bar engagement portion 54B of the lock bar 54 is in contact with the release surface 50B of the cam portion 50 from the state where the cam portion engagement portion 54B is disposed in the first cutout portion 50A1 of the cam portion 50. 54 is moved in a direction away from the knob body 14. As a result, the restricting portion 54C of the lock bar 54 is disengaged from the lock bar engaged portion 14A of the knob body 14. As a result, the rotational lock of the knob 12 (knob main body 14) is unlocked, and the knob 12 can be rotated from the "P" position to the "R" position, the "N" position and the "D" position.
また、ノブ12が「P」位置から「N」位置又は「D」位置に配置された場合(ノブ12のシフト位置が「N」位置又は「D」位置であることをシフトセンサが検出した場合)には、シフトロック機構46において、制御装置の制御により、モータ26が正駆動されて、伝達機構28(ウォームギア30、中間ギア36及びノブ駆動ギア18)を介して、カム構成体52が矢印E側へ向けて回転される。また、カム構成体52が矢印E側へ向けて回転されると、図5A及び図5Bに示されるように、ロックバー54のカム部係合部54Bがカム部50の解除面50Bに当接している状態から当該カム部50の第1切欠部50A1内に配置された状態となる。そして、ロックバー54のカム部係合部54Bがカム部50の第1切欠部50A1内に配置された状態では、ロックバー54が図示しないスプリングの付勢力によってノブ本体14側へ移動されて、ロックバー54の規制部54Cがノブ本体14のロックバー被係合部14Bにおける第1被係合部14B1に挿入される。これにより、ノブ12(ノブ本体14)の回転範囲が「N」位置から「D」位置の間に制限される。
In addition, when the knob 12 is disposed at the “N” position or the “D” position from the “P” position (when the shift sensor detects that the shift position of the knob 12 is the “N” position or the “D” position) In the shift lock mechanism 46, the motor 26 is positively driven by the control of the control device, and the cam structure 52 is an arrow via the transmission mechanism 28 (the worm gear 30, the intermediate gear 36 and the knob drive gear 18). It is rotated toward the E side. Further, when the cam assembly 52 is rotated toward the arrow E, as shown in FIGS. 5A and 5B, the cam portion engaging portion 54B of the lock bar 54 abuts on the release surface 50B of the cam portion 50. In this state, the cam portion 50 is disposed in the first cutout portion 50A1 of the cam portion 50. Then, in a state where the cam portion engaging portion 54B of the lock bar 54 is disposed in the first notch portion 50A1 of the cam portion 50, the lock bar 54 is moved toward the knob main body 14 by the biasing force of a spring not shown. The restricting portion 54C of the lock bar 54 is inserted into the first engaged portion 14B1 of the lock bar engaged portion 14B of the knob main body 14. Thereby, the rotation range of the knob 12 (knob main body 14) is limited between the "N" position and the "D" position.
一方、ブレーキの操作や解除ボタンが操作される等の所定の操作がなされた際には、シフトロック機構46において、制御装置の制御により、モータ26が逆駆動されて、伝達機構28を介して、カム構成体52が矢印F側へ向けて回転される。また、カム構成体52が矢印F側へ向けて回転されると、ロックバー54のカム部係合部54Bがカム部50の第1切欠部50A1内に配置された状態から当該カム部50の解除面50Bに当接している状態となる。そして、ロックバー54のカム部係合部54Bがカム部50の第1切欠部50A1内に配置された状態からカム部50の解除面50Bに当接している状態とされることで、ロックバー54がノブ本体14と離間する方向へ向けて移動される。その結果、ロックバー54の規制部54Cが、ノブ本体14のロックバー被係合部14Bにおける第1被係合部14B1内から離脱される。これにより、ノブ12(ノブ本体14)の回転範囲の制限が解除されて、ノブ12が「P」位置から「R」位置、「N」位置及び「D」位置に回転可能にされる。
On the other hand, when a predetermined operation such as the operation of the brake or the release button is performed, the motor 26 is reversely driven in the shift lock mechanism 46 by the control of the control device, and the transmission mechanism 28 is performed. The cam assembly 52 is rotated toward the arrow F side. Further, when the cam structure 52 is rotated toward the arrow F side, the cam portion engaging portion 54B of the lock bar 54 is disposed in the first cutout portion 50A1 of the cam portion 50, and the cam portion 50 It will be in the state which is in contact with release side 50B. The cam bar engagement portion 54B of the lock bar 54 is in contact with the release surface 50B of the cam portion 50 from the state where the cam portion engagement portion 54B is disposed in the first cutout portion 50A1 of the cam portion 50. 54 is moved in a direction away from the knob body 14. As a result, the restricting portion 54C of the lock bar 54 is disengaged from the inside of the first engaged portion 14B1 of the lock bar engaged portion 14B of the knob main body 14. As a result, the limitation of the rotation range of the knob 12 (knob body 14) is released, and the knob 12 can be rotated from the "P" position to the "R" position, the "N" position and the "D" position.
さらに、ノブ12が「N」位置に配置された場合(ノブ12のシフト位置が「N」位置であることをシフトセンサが検出した場合)で、かつ、ロックスイッチが操作された際には、シフトロック機構46において、制御装置の制御により、モータ26が正駆動されて、伝達機構28(ウォームギア30、中間ギア36及びノブ駆動ギア18)を介して、カム構成体52が矢印E側へ向けて回転される。また、カム構成体52が矢印E側へ向けて回転されると、図5A~図5Dに示されるように、ロックバー54のカム部係合部54Bがカム部50の解除面50Bに当接している状態から当該カム部50の第2切欠部50A2内に配置された状態となる。そして、ロックバー54のカム部係合部54Bがカム部50の第2切欠部50A2内に配置された状態では、ロックバー54が図示しないスプリングの付勢力によってノブ本体14側へ移動されて、ロックバー54の規制部54Cがノブ本体14のロックバー被係合部14Bにおける第1被係合部14B1及び第2被係合部14B2に挿入される。これにより、ノブ12(ノブ本体14)の回転がロック(規制)されて、ノブ12の「N」位置から「R」位置、「P」位置及び「D」位置への回転がロック(規制)される。なお、図5Eに示されるように、カム構成体52が矢印E側へ向けてさらに回転されることにより、第2切欠部50A2における矢印F側の面とロックバー54のカム部係合部54Bとをノブ本体14の回転径方向にオーバーラップさせることにより、ロックバー54の径方向外側(ノブ本体14の回転径方向外側)への移動を規制することができる。
Furthermore, when the knob 12 is disposed at the “N” position (when the shift sensor detects that the shift position of the knob 12 is at the “N” position), and when the lock switch is operated, In the shift lock mechanism 46, the motor 26 is positively driven by the control of the control device, and the cam structure 52 is directed to the arrow E side via the transmission mechanism 28 (the worm gear 30, the intermediate gear 36 and the knob drive gear 18).
