PURPOSE:To provide an intra-tube moving unit to travel inside of a tube having a small bore, with which movement takes place while strain element actuators are pressed to the tube wall and also communications are made by the use of these actuators. CONSTITUTION:An intra-thin tube moving unit is composed of strain element actuators 2 for generating movement, a linear mechanism part 3 to press the actuator to the tube wall, and a coordinative control drive part 4 having a communication part 6 and making control drive in coordination with the actuators. |
