Abstract

　ブレーキ装置において、組立性を向上させると共に大型化を抑える。本発明に係るブレーキ装置では、固定側ブレーキ部材(４)は、シャフト(２)の軸方向に沿って回転側ブレーキ部材(３)に近接する方向である第１方向側に移動することによって回転側ブレーキ部材(３)に接触して制動力を生じさせ、第１方向と反対の第２方向に移動することによって回転側ブレーキ部材(３)から離反して制動を解除する。第１ハウジング(５１)は、第１収納部(５３)を有し、第１収納部(５３)より第２方向側の部分の内径が第１収納部(５３)の内径以上である。スペーサーは、固定側ブレーキ部材(４)の第２方向側に配置され、第１ハウジング(５１)と別体の部材である。ピストン(７)は、小径部(７１)と大径部(７２)とを有し、スペーサーの第２方向側の端面と大径部(７２)との間に圧油が供給される油圧室が構成される。付勢部材(８)は、ピストン(７)を第１方向側に付勢する。
