A geared motor, wherein directions perpendicular to each other are referred to as an X-direction and a Y-direction, and a direction perpendicular to the X-direction and the Y-direction is referred to as a Z-direction, wherein the geared motor comprises: a case, comprising a case body part which opens toward one side in the X-direction, and a bottom plate part located on the other side in the X-direction with respect to the case body part; a cover which covers an opening of the case body part of the case on the one side in the X-direction; a motor which is disposed inside the case; a plurality of motor lead wires flexibly connected with the motor; and a gear train disposed in the case on one side in the Y-direction with respect to the motor in a manner that turning center axial lines of gears included in_the gear train are directed in the X-direction; the geared motor being characterized in that the case comprises a motor lead wire passage whose depth direction is the X-direction and which is located inside the case and on the bottom plate part and extended in the Y-direction so as to pass through a space among the bottom plate part, the gears included in the gear train, and the case body part, wherein a support shaft is formed on the bottom plate part and turnably supports a drive gear of the gears, a plate-shaped projection (351, 352) is disposed between a side plate part of the case body part and the support shaft, and the motor lead wire passage is in a slit shape which opens toward the X-direction and is formed among the side plate part, the plate-shaped projection (351, 352), and the bottom plate part; wherein the plurality of the motor lead wires comprise a connecting position connected to the motor and are bent from the connecting position to be disposed in the motor lead wire passage so as to be extended from the other side to the one side in the Y-direction through the motor lead wire passage while keeping a distance from the gears included in the gear train wherein each of the motor lead wires comprises a first portion which is extended from the connecting position, a second portion which is bent from an end part of the first portion to the other side in the X-direction and is extended in the motor lead wire passage, and a third portion which is bent from an end part on the other side in the X-direction of the second portion to the one side in the Y-direction and is extended in the motor lead wire passage, wherein the plurality of the motor lead wires is juxtaposed in the X-direction and extended in the Y-direction in the motor lead wire passage, and wherein the case is provided with a lead wire receiving part which is obliquely inclined from the X-direction to the Z-direction in the motor lead wire passage, and the third portions of the plurality of the motor lead wires are juxtaposed in the X-direction in an obliquely inclined state in the Z-direction along the lead wire receiving part. a case, comprising a case body part which opens toward one side in the X-direction, and a bottom plate part located on the other side in the X-direction with respect to the case body part;
