To provide a multi-shaft driving device that aims for a lightening of weight and lowering of cost as compared with conventional structures. In a structure in which, when a movable shaft (40) is slidably installed at an output shaft (20) and advances toward an input-side bevel gear (14), an output-side bevel gear (50) of a distal end side of the movable shaft (40) meshes-together with the input-side bevel gear (14), and the movable shaft (40) rotates and rotation of this movable shaft (40) is transmitted to the output shaft (20), the movable shaft (40) and the output-side bevel gear (50) are molded integrally of resin, and the output shaft (20) also is formed of resin, and the movable shaft (40) is slidably exteriorly placed on an outer peripheral side of the output shaft (20).

1. An output member comprising: an output shaft that is made of resin and that is applied to a mechanical device for a vehicle;a movable shaft that is made of resin and is installed at the output shaft;an output-side clutch member that is made of resin and is provided integrally with the movable shaft;a guide portion that is structured by a shape of an outer peripheral surface of one of the output shaft and the movable shaft and a shape of an inner peripheral surface of another of the output shaft and the movable shaft, and that makes the movable shaft able to slide in an axial direction and unable to rotate relatively, with respect to the output shaft, wherein the inner peripheral surface of the other engages with the outer peripheral surface of the one of the output shaft and the movable shaft; andan urging member that urges the movable shaft in one direction or another direction opposite to the one direction in the axial direction,wherein the urging member is disposed at interiors of the output shaft and the movable shaft,a guide hole that opens toward a distal end side is formed in the output shaft, and a coil spring that serves as the urging member is accommodated in the guide hole, and a positioning portion, that positions an end portion of the coil spring, is provided at the movable shaft, andthe output-side clutch member is an output-side bevel gear that, when the movable shaft slides in the one direction, is configured to mesh-together with an input-side bevel gear that serves as an input-side clutch member. 2. The output member of claim 1, wherein the guide portion is structured from an outer-side engaging portion, that is convex and concave in cross-section and is formed along the axial direction at the outer peripheral surface of the one of the output shaft and the movable shaft, and an inner side engaging portion, that is convex and concave in cross-section, is formed at the inner peripheral surface of the other of the output shaft and the movable shaft, and engages with the outer-side engaging portion so as to be slidable in the axial direction. 3. The output member of claim 1 wherein: the one of the output shaft and the movable shaft is formed in a polygonal shape in cross-section, and an inner peripheral surface of the other of the output shaft and the movable shaft is formed in a polygonal shape in cross-section that engages with a polygonal outer peripheral surface of the one so as to be slidable in the axial direction, andthe guide portion is structured by the polygonal outer peripheral surface of the one and the polygonal inner peripheral surface of the other. 4. The output member of claim 1, wherein an inner peripheral surface of the movable shaft and an outer peripheral surface of the output shaft are engaged. 5. The output member of claim 4, wherein the positioning portion is a projection that is inserted in the end portion of the coil spring. 6. The output member of claim 1, wherein the output-side clutch member is molded integrally with the movable shaft. 7. A multi-shaft driving device comprising: a plurality of the output members of claim 1 whose respective output shafts are connected via transmitting members to a plurality of movable mechanisms provided at a vehicle;a plurality of input-side clutch members that are provided so as to correspond respectively and individually to the plurality of output members, and, when the movable shaft of the corresponding output member slides in the one direction, the input-side clutch member connects with the output-side clutch member, wherein drive power of a motor is transmitted to the input-side clutch member and the input-side clutch member is rotated; anda selector member that, by sliding the movable shaft of a selected output member among the plurality of output members from a usual position toward an urging direction by the urging member or by pushing and sliding the movable shaft of the selected output member against the urging member, connects the output-side clutch member of the selected output member to the corresponding input-side clutch member.
