PROBLEM TO BE SOLVED: To provide a parking mechanism with a short entire length.SOLUTION: A parking mechanism 100 includes: a park piston 3 having a pressure receiving surface configured to receive working hydraulic pressure, and integrally moving with a parking rod 5 according to the working hydraulic pressure; energization means 48 of energizing the park piston 3 to a reverse direction to force from the working hydraulic pressure; and a lock mechanism 7 capable of regulating movement of the park piston 3 by being engaged with the park piston 3. When the lock mechanism 7 is viewed from a direction orthogonal to a movement direction of the park piston 3, an engagement position between the lock mechanism 7 and the park piston 3 overlaps with the energization means 48.SELECTED DRAWING: Figure 1
【課題】全長を短くするパーキング機構を提供する。【解決手段】作動油圧がかかる受圧面を有し、作動油圧に応じてパーキングロッド5と一体的に移動するパークピストン3と、作動油圧による力とは逆方向にパークピストン3を付勢する付勢手段48と、パークピストン3に係合することでパークピストン3の移動を規制可能なロック機構7とを備えたパーキング機構100であって、パークピストン3の移動方向と直交する方向からロック機構7を見た場合、ロック機構7とパークピストン3との係合位置が、付勢手段48と重なる。【選択図】 図1
