For elder people with stairs in their homes, it will be increasingly inconvenient. Therefore, elevators are more important in home life. In recent years, European countries and the United States have developed home elevator technology. Japan also began to have the small elevator standard. 　　This research focus the small elevator driven by ball screw that under the standard of American Society of Mechanical Engineers (ASME) specification. Such as: maximum load, operating speed, etc. For the stress and deformation of the components in the ball screw type elevator, this research do mechanical analysis to see the changes of stress during running test. The products of the ball screw and linear guideway are based on the domestic manufacturers. The rest of parts are purchased on the market. Afterward the finite element analysis (Ansys Workbench) is used to do the elevator static simulation and use Adams software to do movement simulation. 　　Whether or not the components in this research are in the allowable stress. It is determined by standard of ASME whether there is any possibility of damage. According to the safety factor of every component, the simulated stress values in this research are all within the allowable stress. Therefore, every component will not be damaged.
