PROBLEM TO BE SOLVED: To accurately detect motion of a finger by composing each revolute joint part so as to extend and contract following extension and contraction of the finger. SOLUTION: The finger motion tracking detector has two arm members 8 and 9 with base end parts of each revolute joint part 5 swingably supported by adjacent joints respectively via base end shafts 6 and 7, a connecting member 12 with both end parts swingably supported on tips of the two arm members respectively via tip shafts 10 and 11 and connecting the arm members, two base part gears 13 and 14 arranged on the same axes as the base end shafts and respectively fixed to the adjacent joints, two intermediate gears 15 and 16 rotatably journaled to the two arm members respectively and meshing with the base part gears, two tilting gears 17 and 18 arranged on the same axes as the tip shafts, respectively fixed to both end parts of the connecting member, meshing with the intermediate gears and having pitch circle radii larger than the base part gears, two mutually meshing interlocking gears 19 and 20 arranged on the same axes as the tip shafts and respectively connected to the tips of the two arm members, and an angle change detecting means 21 of detecting an angle change between the adjacent joints.
