To provide a gear box which can inhibit deflection of a housing when a pinion gear is fixed, and to provide a drive device and an electronic device.SOLUTION: A gear box includes: a housing 10 having a partition part 61; a support shaft 100 fixed to the partition part 61; and an output shaft 120 which is disposed in a +Z direction relative to the partition part 61 and is supported so as to rotate around the support shaft 100 and to which a pinion gear 150 is fixed. The housing 10 has a partition wall 33 which is located in a -Z direction relative to the partition part 61, extends in the Z direction, and may contact with the support shaft 100. The partition wall 33 forms a part of a motor housing part which houses a motor.SELECTED DRAWING: Figure 5 【課題】ピニオンギヤの固定時における筐体の撓みを抑制できるギヤボックス、駆動装置及び電子機器を提供する。【解決手段】仕切部６１を有する筐体１０と、仕切部６１に固定された支持軸１００と、仕切部６１に対して＋Ｚ方向に配置されるとともに、支持軸１００回りに回転可能に支持され、ピニオンギヤ１５０が固定される出力軸１２０と、を備え、筐体１０は、仕切部６１に対して−Ｚ方向に位置し、Ｚ方向に延在するとともに、支持軸１００に当接可能な区画壁３３を有し、区画壁３３は、モータを収容するモータ収容部の一部を構成している。【選択図】図５
