PROBLEM TO BE SOLVED: To provide a medical robot and a mounting portion of the medical robot, which can easily improve operability and simplify the configuration. SOLUTION: A surgical tool 40 having a main body 41 provided with a driven side hole in which a driven portion for transmitting a driving force and a driven portion are arranged so as to be relatively linearly movable, a mounting surface 21 and a driven portion A mounting portion 20 having a transmission side hole 24 in which a transmitting portion 22 for transmitting a driving force in the linear motion direction is arranged is provided, and the surgical tool 40 and the mounting portion 20 are respectively provided with the surgical tool 40 and the mounting portion 20. The surgical tool engaging portions 51 and 52 and the mounting engaging portion 31 that mount the surgical tool 40 on the mounting portion 20 by moving relative to the mounting surface 21 and in a direction intersecting the linear motion direction. , 35 are provided, and the mounting surface 21 is a groove extending in a direction in which the surgical tool 40 moves relative to the mounting portion 20, and is a guide groove for guiding the driven portion to a predetermined position of the transmission side hole 24. It is characterized in that 25 is provided.
