PROBLEM TO BE SOLVED: To eliminate a transmission loss and to prevent the occurrence of allophone.SOLUTION: A driving force transmission device 10 includes a first rotating member 13 provided to be rotatable relative to a shaft member 11 and rotatable by a turning motor MT; a second rotating member 14 provided to be non-rotatable relative to the shaft member 11; and an energizing means 15 capable of causing the contact and separation of the first rotating member 13 and second rotating member 14. The driving force transmission device 10 transmits a driving force from the turning motor MT to the shaft member 11 when the first and second rotating members 13, 14 abut on each other. The first and second rotating members 13, 14 have abutting surfaces 22, 25 abutting on each other, respectively, and a pressure detecting means 18 is provided for detecting the pressure of the abutting surfaces 22, 25. The energizing force of the energizing means 15 is adjustable based on the detection result of the pressure detecting means 18. |
