PURPOSE: A bearing device of a structure is provided to allow a structure to be horizontally slid in an earthquake and to limit sliding which exceeds a specific range. CONSTITUTION: A bearing device(100) of a structure comprises a lower plate(110), an upper plate(120), a sliding allowance unit(130), and a sliding limit unit(140). The lower and upper plates are installed in lower and upper structures(10,20) to face each other. The sliding allowance unit has a sliding pad(132) and a sliding plane part(134). The sliding pad is formed in the lower plate and receives the load of the upper structure. The sliding plane part is formed on the upper plate and is contact with the sliding pad. The sliding limit unit has a sliding limit protrusion(142) and a protrusion housing(144). The sliding limit protrusion is protruded from the lower plate. The protrusion housing is formed in the upper plate to accept the sliding limit protrusion leaving a sliding allowance space(S).
