The present invention relates to a device for adjusting the height of the handrail that can be raised and lowered on both sides of the bed, the bed 100 is provided with a mattress (1), a cuboid-shaped base (3) installed below the bed (100)； First handrails 4 respectively lifting up and down along the left side of the mattress 1 from the inside of the base 3； A plurality of rails (35, 36) respectively installed inside the first handrail (4)； Lifting members 33 and 34 meshed with the rails 35 and 36； Second railings 5 respectively lifting up and down along the right side of the mattress 1 from the inside of the base 3； A plurality of rails (45, 46) respectively installed inside the second railing (5)； Elevating members 43 and 44 engaged with the rails 45 and 46； A controller 20 installed inside the base 3 to output a control signal as a signal received from the outside； A first electric motor 30 and a second electric motor 40 installed inside the base 3 to forward and reverse rotation with a control signal to the controller 20； A first power transmission member 32 which reduces the rotational force of the first electric motor 30 through the reduction gear 31 and then transfers it to each of the lifting members 33 and 34； And a second power transmission member 42 which transmits the rotational force of the second electric motor 40 to each of the elevating members 43 and 44 after decelerating the rotational force of the second electric motor 40. At least one of the first electric motor 30 and the second electric motor 40 is driven by the control signal to elevate the first handrail 4 and the second handrail 5. The present invention improves the functionality of the bed by installing handrails that can be lifted on both sides of the bed, and lifting the handrail from a remote control, thereby eliminating the risk of falling or anxiety while sleeping.본 고안은 침대 양측에 승강이 가능한 난간의 높낮이를 조절하는 장치에 관한 것으로, 매트리스(1)가 구비된 침대(100)에 있어서, 상기 침대(100) 아래에 설치되는 직육면체 형상의 베이스(3)； 상기 베이스(3) 내측
