項１に記載の減速機。[Claims for Utility Model Registration] (1) A gear case, a gear reduction mechanism disposed within the gear case, and a gear reduction mechanism that is supported by a ball bearing fixed to the gear and that extends from one side of the gear case to the outside. The gear case is formed so as to cover one surface of the gear case, and includes an output shaft of the gear reduction mechanism that has been led out, a bearing fitting part that fits the ball bearing, and a hole that leads out the output shaft. A reducer comprising: a cover screwed to the output shaft; and a gasket formed in an annular shape surrounding the output shaft and sandwiched between the inner surface of the cover and the ball bearing, wherein the gasket has low friction. The inner diameter of the packing is set equal to the outer diameter of the output shaft, and the outer diameter of the packing is set to be slightly smaller than the outer diameter of the ball bearing. Characteristic reducer. (2) The speed reducer according to claim 1, wherein the packing is made of cork.
