PROBLEM TO BE SOLVED: To improve the fastening responsiveness, while restricting the drag torque in a friction engagement part. SOLUTION: This start clutch for an automobile is provided with a clutch housing 57, a clutch hub 59, a friction multi-plate clutch 129 for transmitting the torque between the clutch housing 57 and the clutch hub 59, a pressurizing member set 137 for generating the thrust to fasten the friction multi-plate clutch 129, and an electric motor 171 for rotating to drive one member 141 of the pressurizing member set 137 to generate the relative rotation between the members 139 and 141. A control means is provided to control the electric motor 171 so that the pressurizing member set 137 is positioned in a neutral position, wherein looseness is generated, and a looseness-eliminated position, wherein the generation of looseness is restricted, in response to the condition of the automobile.
