Abstract: A brake device (1) comprises a wheel brake (100) having a brake shoe (120) accommodated in a drum (110). The brake device (1) comprises: an input lever (20) that is pivotably connected to the drum (110); and an operation amount detection device (50) that detects the operation amount of the input lever (20). At least part of the operation amount detection device (50) is accommodated in the drum (110), and has a rotation angle sensor (51) that detects the pivot amount of a support shaft (22) of the input lever (20) inserted in the drum (110). With this configuration, the operation amount of the input lever (20) can be detected and the number of components can also be reduced.
