PROBLEM TO BE SOLVED: To provide a speed changer which can alleviate shock even if ground plane of a wheel is changed and friction is changed.SOLUTION: A speed changer comprises: an input shaft 102 to which driving force from a motor 3, which is mounted on an automobile 2 of which a front wheel 6 and a rear wheel 7 are driven, is transmitted; a front wheel side output shaft 104 which is located in parallel to the input shaft 102, and outputs driving force to the front wheel 6; a rear wheel side output shaft 106 which is located in parallel to the input shaft 102 and the front wheel side output shaft 104, and outputs driving force to the rear wheel 7; a front wheel side shift mechanism 130 which can so transmit rotation of the input shaft 102 to the front wheel side output shaft 104 as to be capable of freely changing gear; a rear wheel side shift mechanism 150 which can so transmit rotation of the input shaft 102 to the rear wheel side output shaft 106 as to be capable of freely changing gear; a front wheel side clutch 170 which is provided on a power transmission path from the front wheel side shift mechanism 130 to the front wheel 6; and a rear wheel side clutch 190 which is provided on a power transmission path from the rear wheel side shift mechanism 150 to the rear wheel 7.SELECTED DRAWING: Figure 1

    【課題】車輪の接地面が変化し摩擦が変化しても衝撃を緩和できる変速機を提供する。【解決手段】前輪6及び後輪7が駆動される自動車2に搭載される原動機3からの駆動力が伝達される入力軸102と、入力軸102に対して平行に配置され、且つ前輪6へ駆動力を出力する前輪側出力軸104と、入力軸102及び前輪側出力軸104に対して平行に配置され、且つ後輪7へ駆動力を出力する後輪側出力軸106と、入力軸102の回転を変速自在に前輪側出力軸104へ伝達可能な前輪側変速機構130と、入力軸102の回転を変速自在に後輪側出力軸106へ伝達可能な後輪側変速機構150と、前輪側変速機構130から前輪6までの間の動力伝達経路に設けられた前輪側クラッチ170と、後輪側変速機構150から後輪7までの間の動力伝達経路に設けられた後輪側クラッチ190とを備える。【選択図】図1
