ABSTRACT:
A gear transmission comprises a traveling load detection element including an upstream detection member, a downstream detection member and a biasing member. One of the upstream and downstream detection members is an axially slidable detection member which is axially slidable along an output shaft. One of the upstream and downstream detection members has a first engagement part and a second engagement part. The first engagement part and the second engagement part generate respective forces for sliding the axially slidable detection member opposite to the biasing direction of the biasing member. The forces are changed according to variation of the traveling load.
