PURPOSE:To prevent the occurrence of a tight corner braking phenomenon by employing a viscous fluid coupling for linking mutually parallel two output shafts. CONSTITUTION:A linking mechanism 20 is provided between a first shaft 12 and a second shaft 13 and a viscous coupling 30 is provided on the first shaft 12. The linking mechanism 20 is formed with a transmitting mechanism consisting of a drive sprocket 21 rotatably installed on the first shaft 12, a driven sprocket 22 rotatably installed on the second shaft 13, and a chain 23 put around both sprockets 21, 22, and a clutch hub 24 and a first coupling sleeve 25 which are installed on the second shaft 13. |
