Abstract
【解決手段】 第1ピストン部材46の軸方向の一方の端部に径方向に平行な径方向面76aを有する嵌合溝76を形成し、第2ピストン部材48に、先端部が基部に対して軸方向に突き出すように曲げられた周方向の長爪70を形成し、その長爪70の先端部に第1ピストン部材46の嵌合溝76に嵌合してその嵌合溝76の径方向面76aに当接させられる嵌合爪72を形成する。長爪70は軸方向に弾性力を有するので、第1ピストン部材46は長爪70により軸方向に付勢される。従って、第1ピストン部材46の軸方向のがたつきが低減させられるので、ピストンおよび摩擦係合要素の耐久性が向上するとともに、ピストンの作動効率、および自動変速機の伝達効率が向上する。
