'The shift lever 51 is shifted by the gear 511 to shift the misalignment 5 2 1 on the shaft 5 2 so that the guide pin 6 1 3 2 of the guide rod 6 1 3 can be shifted to the valley 5 21 side. The guide rail 5 2 2 1 of the guiding member 52 2 slides on the guide rod 613 ′ of the pushing end 61 of the carriage #6 to thereby push the guiding member $ 2 2 to push the force of the guiding pin 613 2 , The stop portion 613 1 is transmitted to the elastic member 612 via the guiding rod 613, and the elastic member 612 further applies the top thrust to the pushing end 6 of the car #6 to push the parking arm 6 The upward movement of the end 61 due to the upward movement of the pushing end 61 of the arm 6 can cause the locking end 62 of the parking arm 6 to swing downward synchronously, at which time the torsion spring 64 will also be driven and tightened. In this way, the studs 6 2 of the carding end 6 2 can be inserted into the troughs 5 3丨a of the parking gear 5 31, whereby the parking gear 5 3丄 can no longer be rotated to further achieve the lock. Live the main shaft 5 3 and lock the target of the rear wheel, so that the vehicle stops When there is a stable state. When the lever is not in the parking stall? In the position, the guide pin 6 ^ 2 can also slide along the guide rail 5 2 of the shifting hub 52 and the working side guiding member 5 2 2 , so that the pushing end 6 i of the parking arm 6 is no longer pushed. The guiding rod 6 is on the front of the 3: the stopping part 613!, when the pushing end 6 of the parking arm 6 is no longer subjected to the top thrust, 1304120 ^ receives the (four) pieces of the forced top thrust of the 5 2 2, when the card is made When the stud 6 2 of the end 6 2 is topped on the tooth bee 5 3 ib of the parking gear 5 31, the parking arm 6 will not be driven by the tank 5 2 2 · the force (4) Na, and there will be no groove The lack of it. In summary, the present invention can achieve the effect and purpose of the claim by the above-mentioned parking right structure, and should meet the requirements of practicability, novelty, and progressiveness, and apply for an invention patent according to law. The detailed examination of the examiner, Huisei granted the examination and approval of the invention patent, to the sense of virtue.
