Abstract
A pivotal assembly applied to a board includes a first board, a first pivotal member, and a pivotal plate. The first pivotal member is fixed to the first board and has a first retaining structure. The pivotal plate is pivotally connected to the first pivotal member and has a first protrusion. The first protrusion is retained in the first retaining structure, so as to make the first board limitedly rotate to be perpendicular or parallel to the pivotal plate.
