摘要： PROBLEM TO BE SOLVED: To restrain occurrence of a hump condition of a main clutch so as to prevent the main clutch from being worn and damaged during movement by a wrecker vehicle mounted with a drive force transmitting device for actuating the main clutch by means of a pilot clutch mechanism. SOLUTION: A front housing 1 which is an outer rotary member is made of a material having a large degree of thermal expansion and a small degree of rigidity so as to restrain affection upon the frictional engagement between a main clutch 10c, and accordingly, the time by which the main clutch 10c restrains abnormal, frictional engagement of the main clutch 10c caused by elastic deformation of the housing 11a, thereby it is possible to prevent friction and damage of the main clutch 10c.

摘要： PROBLEM TO BE SOLVED: To avoid damage, excessive abrasion, etc., of a clutch mechanism and draw out as much possibility of escaping from a slipping state as possible while maintaining durability of these mechanical systems. SOLUTION: A wheel speed signal ni is input (step 510), rotating speed m2 of the slowest wheel is found from the input wheel speed signal ni (step 520), and when a value of the rotating speed m2 of the slowest wheel is not more than a specified value v2, a value of return code RC is set to 1 (failed in escaping) (step 540). In step 550, a value of the return code RC is set to 0 (succeeded in escaping). It is possible to precisely judge the slipping state of a vehicle by using a sliding and staying state judgement means to judge success/ failure of escaping from the slipping state as above, and a trial of escaping by all the drivable wheels is never interrupted in the case when the vehicle is almost in the process of escaping from the slipping state, etc. Possibility in succeeding in escaping increases by these judging processes (sliding and staying state judgement means).
