A damper device includes an input-side rotating member, an intermediate rotating member, an output-side rotating member, and an elastic body. The elastic body is located in a clearance in a circumferential direction between each of a plurality of corresponding portions in which a hook portion of the input-side rotating member and a hook portion of the output-side rotating member face each other and the intermediate rotating member. A part of the corresponding portions is a first corresponding portion configured in such a manner that the elastic body is separated from the output-side rotating member and in contact with the input-side rotating member. The remainder of the corresponding portions is a second corresponding portion configured in such a manner that the elastic body is separated from the input-side rotating member and is in contact with the output-side rotating member.

A control device of a vehicle includes between an engine and an automatic transmission a fluid transmission device transmitting power from a pump impeller coupled to the engine via a fluid to a turbine impeller coupled to the automatic transmission. The control device determines occurrence of a lost-drive state of the fluid transmission device based on an increase amount of a rotation speed of the engine after a predetermined time during start of the engine.

In a torsional vibration reducing device, a protrusion projecting radially outward of the rotating body is formed on an inner wall surface. The protrusion is formed on a rotation direction side of a rotating body relative to a straight line passing through a rotation center of the rotating body and a center of a rolling element when the rolling element is located in a middle between both end positions to which the rolling element swings within the roller chamber, and while the rolling element is located at an end portion of a roller chamber on the rotation direction side of the rotating body, a gap is equal to or less than a predetermined value between the rolling element and a wall surface of the roller chamber on a straight line passing through a rotation center of the rotating body and a tip of the protrusion.

A map is provided that has an unlimited region where a take-off slip-engagement the next time is repeatedly executed indefinitely, a limited region where the take-off slip-engagement the next time is repeatedly executed only once, and a prohibited region where the take-off slip-engagement the next time is prohibited, and has a generated heat amount during the take-off slip-engagement and an elapsed time after the lock-up slip-engagement ends as variables. Therefore, a region in which the take-off slip-engagement the next time had been prohibited because the take-off slip-engagement the next time is unable to be repeatedly executed indefinitely even though it is able to be repeatedly executed only once is made the limited region, so the take-off slip-engagement the next time is allowed to be repeatedly executed only once.
