Abstract
A brake device arranged between a drive shaft and a driven shaft arranged coaxially with the drive shaft is disclosed. The brake device includes a first rotor, a second rotor, an engagement member, a braking mechanism, and a cam mechanism. The braking mechanism includes a movable friction member rotatable integrally with the second rotor, a fixed friction portion, and an urging member that urges the movable friction member toward the fixed friction portion. When rotational force is provided from the drive shaft to the first rotor, the cam mechanism permits transmission of rotation of the drive shaft to the driven shaft. When the rotational force is provided from the driven shaft to the second rotor, the cam mechanism restricts rotation of the driven shaft. The cam mechanism is provided independently from the engagement member.
