CONSTITUTION: An arm structure of a robot comprises a fixed base part(21), a first arm part(22), a second arm part(23), a motor(53), a first conveyor belt(55), a second conveyor belt(56), and a relay member(54). The first arm part is connected to the fixed base part through a first speed reducer(51) and the second arm part is connected to the first arm part through a second speed reducer(52). The second conveyor belt conveys a driving force of the motor with respect to the relay member. The first conveyor belt conveys the driving force of the motor to the first speed reducer. The driving force of the motor is conveyed from the second conveyor belt through the relay member.
