ABSTRACT

According to one embodiment, a parallel link mechanism includes a base
portion, a movable portion, a braking unit, motors, links, and a switching
unit. The movable portion is separated from the base portion in a first
direction. The braking unit is provided between the base portion and the
movable portion, and includes braking pads. The motors are provided around the
braking unit, and each include a drive shaft extending along a direction
intersecting the first direction. The links are each coupled between the drive
shafts and the movable portion. The switching unit is provided between the
base portion and the movable portion. The switching unit is configured to
switch, by moving the braking pads, between a contact state in which the
braking pads are in contact with the drive shafts and a non-contact state in
which the braking pads are separated from the drive shafts.
