To prevent P-off at parking on a slope while suppressing the size enlargement of a device.SOLUTION: A first fixing part 110 is arranged at a first roller 62, and a second fixing part 112 is arranged at a second roller 64. When a push-out load for pushing out a parking pole 40 from a parking gear at parking on a slope is generated, a lock-side engagement face 40a of the parking pole 40 is push-pressed to the first fixing part 110, the second fixing part 112 is push-pressed to a guide face 94, and slide friction is generated at contact parts of these items. The rotation resistance of the first roller 62 and the second roller 64 becomes large on the basis of the slide friction, a force in a direction in which a lock member retreats to a lock release position side is reduced, and P-off is thereby suppressed. In this case, since it is necessary just to install the first fixing part 110 at the first roller 62 and to install the second fixing part 112 at the second roller 64, a parking lock mechanism is simplified in a structure, reduced in a size, and can be inexpensively manufactured.SELECTED DRAWING: Figure 7

    【課題】装置の大型化を抑制しつつ坂路での駐車の際のP抜けが防止されるようにする。【解決手段】第1ローラ62に第1固定部110が設けられるとともに、第2ローラ64に第2固定部112が設けられており、坂路での駐車の際にパーキングポール40をパーキングギヤから押し出す押出し荷重が発生すると、パーキングポール40のロック側係合面40aが第1固定部110に押圧されるとともに、第2固定部112がガイド面94に押圧され、それ等の接触部で滑り摩擦が発生する。この滑り摩擦に基づいて第1ローラ62および第2ローラ64の回転抵抗が大きくなり、ロック部材がロック解除位置側へ後退する方向の力が低減されてP抜けが抑制される。その場合に、第1ローラ62に第1固定部110を設け、第2ローラ64に第2固定部112を設ければ良いため、構造が簡単であり小型で且つ安価に構成することができる。【選択図】図7
