A kind of escapement at brake brake clutch,The brake include an electromagnetism be attracted component magnetic side set one can by the clutch brake shoe for being attracted or recessing,One is set on the outside of clutch brake shoe again to slide for motor force-output shaft embedded in lining together,And the outside of lining sets a link plate for fixing on what motor again,And then the spacer ring for setting a loop shaped is locked between electromagnetism actuation component and link plate,And an enclosure space for being installed with aforementioned clutch brake shoe and lining is formed,With season spacer ring inner peripheral be equipped at intervals with it is several it is convex lead portion,And the clutch brake shoe outer peripheral edge of corresponding position is equipped with the recessed of embedding cunning therewith and leads portion,Clutch brake shoe can only be moved axially and can not be rotated along the convex portion of leading,Therefore the enclosure space for being formed at spacer ring and being installed with clutch brake shoe and lining is penetrated,Enable extraneous sand and dust or other foreign matters and cannot be introduced at the sliding of accumulation what clutch brake shoe,Cleaning inside often protecting,And then it is smooth without hindrance to allow the movement of clutch brake shoe often to protect,Spacer ring both sides of the face process the height to be formed and more unanimously can make more assemble with its parts simultaneously.一種制動器煞車離合處的間隔裝置，該制動器包括一電磁吸合部件的磁吸側設一可受吸合住或退離的離合煞車片，又離合煞車片的外側設一供馬達出力軸滑嵌在一起的來令片，且來令片的外側再設一可供固定於馬達上的連結板，進而設一環圈狀的間隔環被鎖固在電磁吸合部件與連結板之間，而形成一容設前述離合煞車片與來令片的封閉空間，同時令間隔環的內側周緣間隔設有數個凸導部，以及對應處的離合煞車片外周緣上設有與之嵌滑的凹導部，讓離合煞車片只能沿著凸導部軸向移動而無法轉動，故透過間隔環處形成容設離合煞車片與來令片的封閉空間，令外界沙塵或其它異物無法進入堆積於離合煞車片之滑動處、常保內部的清潔，進而讓離合煞車片的移動常保順暢無阻，同時間隔環兩側端面加工形成的高度更能一致而使與其機件更能準確的組裝。
