To use a multi plate friction type engaging mechanism for an application other than a brake device.SOLUTION: A transmission device for harvest machine comprises a brake 55 for braking rotation of a rotation shaft. The brake 55 comprises: a first boss member 56 which rotates with a rotation shaft 44 in an integrated state; a second boss member 57 which can rotate relative to the rotation shaft 44, which is provided between the rotation shaft 44 and the first boss member 56, and is fixed to a fixing part 16; a multi plate friction type engaging mechanism 58 provided between the first boss member 56 and the second boss member 57, and which can be switched between an engaging state for regulating relative rotation of the first boss member 56 and the second boss member 57, and an engaging release state for allowing relative rotation of them; and an operation mechanism 59 for performing a pressing operation of the multi plate friction type engaging mechanism 58.SELECTED DRAWING: Figure 3 【課題】多板摩擦式係合機構を制動装置以外の他の用途にも流用できるようにすることが望まれていた。【解決手段】回転軸の回転を制動するブレーキ５５が備えられ、ブレーキ５５に、回転軸４４と一体回転する第１ボス部材５６と、回転軸４４と相対回転自在で且つ回転軸４４と第１ボス部材５６との間に位置して固定部１６に固定された第２ボス部材５７と、第１ボス部材５６と第２ボス部材５７との間に位置して、第１ボス部材５６と第２ボス部材５７との相対回転を規制する係合状態と、相対回転を許容する係合解除状態とに切り換え自在な多板摩擦式係合機構５８と、多板摩擦式係合機構５８を押圧操作する操作機構５９とが備えられている。【選択図】図３
