Abstract (in Japanese) (See Japanese page) 
(in English) Among human-object interactions, it is important to understand how to grasp objects by human hand. Many researchers tried to classify postures during grasping operations and tackled to understand transition of forces during grasping. However, contact forces of multiple fingers during natural grasping operations with various objects have not been measured and the relationship between contact forces was not clarified. In this study, we measure the contact forces of thumb, index and middle fingers during lifting cylindrical objects with different weights. Seven healthy subjects participated in user experiments to compute the balances of the contact forces for each weight, each subject. Then, the balances for each weight are clarified by support vector machine. The analysis results showed that the subjects were classified into two groups. A difference in the balance of the contact forces was found from the first group, and any difference was not found from the second group.
