To provide an electric parking lock device which can semi-automatically lock a parking gear even if power source failure occurs in the state that the parking gear is not locked.SOLUTION: An electric parking lock device 1 comprises a first electromagnetic solenoid 41 which locks one engagement part 331 against an energization force of a first energization component 31 so that one engagement part 331 does not oscillate during electric conduction, and permits that one engagement part 331 oscillates in a direction of engaging with the other engagement part 332 by the energization force of the first energization component 31 during power source failure. One engagement part 331 is connected to the first energization component 31 provided at a tip of a parking pole 11, and the other engagement part 332 is connected to a brake pedal 60. When depression of the brake pedal 60 is released during electric source failure, a pair of engagement parts 331, 332 engages with each other to oscillate the parking pole 11 in a direction of engaging with a parking gear 12.SELECTED DRAWING: Figure 3

    【課題】パーキングギヤがロックされていない状態のときに電源失陥が生じた場合であっても、半自動的にパーキングギヤをロックすることが可能な電動式パーキングロック装置を提供する。【解決手段】電動式パーキングロック装置1は、通電時には、一方の係合部331が揺動しないように、第1付勢部材31の付勢力に抗して一方の係合部331を係止し、電源失陥時には、第1付勢部材31の付勢力により一方の係合部331が他方の係合部332と係合する方向に揺動することを許可する第1電磁ソレノイド41を備える。一方の係合部331はパーキングポール11の先端部に設けられた第1付勢部材31に接続され、他方の係合部332はブレーキペダル60に接続されている。電源失陥時に、ブレーキペダル60の踏み込みが解除された場合に、一対の係合部331、332が互いに係合し、パーキングポール11をパーキングギヤ12に噛み込む方向に揺動させる。【選択図】 図3
