Further, the protrusion is located between two adjacent wedge block windows.

Further, the outer retainer comprises a left flange and a right flange which are arranged oppositely, a plurality of first beams and second beams are arranged between the left flange and the right flange, two ends of each first beam are respectively arranged on the left flange and the right flange, one end of each second beam is arranged on one of the first beams or the second beams, the other end of each second beam is suspended, each second beam is arranged between two adjacent first beams, a first window for placing a wedge block is formed between each first beam and each second beam, a second window for placing the wedge block is formed between the other two adjacent first beams, each second beam is provided with a connecting section, a transition section and a protruding section, one end of each connecting section is arranged on the transition section, and the other end of each connecting section is arranged on one of the first beams or the second beams, the one end that the linkage segment was kept away from to transition section sets up on the protruding section, transition section is for the inclined plane that upwards inclines gradually the setting by the linkage segment to the protruding section, the protruding section is located the linkage segment top.

Further, a plurality of the bulges are uniformly distributed along the circumference.

A wedge clutch comprises the retainer.

The invention has the beneficial effects that: when the retainer and the wedge type clutch thereof are used, the plurality of protrusions are arranged on the retainer and are gradually in interference fit with the outer raceway, so that the clutch and the outer raceway are integrated, the clutch is ensured to operate stably and reliably, the equipment operates stably and reliably, and the problems that the existing wedge type clutch and the outer raceway are fixedly clamped through a wrenching edge or an oval structure at one side of the outer retainer, the contact surface between the clutch and the outer raceway is limited, the clutch fails due to overlarge relative displacement between the clutch and the outer raceway when the clutch operates, and the equipment is damaged seriously are solved.
