<p><P>PROBLEM TO BE SOLVED: To provide an automatic shift control device capable of reducing the time to be required from a start to a conclusion of the shifting operation, restricting an overload applying to a shift actuator. <P>SOLUTION: This automatic shift control device comprises a transmission having several pairs of shift gear having a different change gear ratio from each other and a gear selecting mechanism for selecting a pair of shift gear for transmitting power, a shift motor 70 for driving the gear selecting mechanism, and a shift power transmitting mechanism 80 for transmitting the power of the shift motor 70 to the gear selecting mechanism. The automatic shift control device also comprises a mechanical fuse 88 provided inside of the shift power transmitting mechanism 80 so as to generate a non-reversible change so that the transmitting power is limited to a predetermined value T or less when the transmitting power exceeds the predetermined value T. <P>COPYRIGHT: (C)2009,JPO&INPIT</p> |
