摘要：
The movable body, having a failure detecting structure which detects a failure in a travelling function of the movable body can be provided with low in cost and the failure detecting portion of the electric wheel chair includes a first speed presuming portion which presumes the straight travelling speed of the electric wheel chair based on an operating signal of the operating device, a second speed presuming portion which presumes the straight traveling speed of the electric wheel chair based on the actual driving amount detected by the actual driving amount detecting device, a speed difference calculating portion which calculates the first straight traveling speed difference which is a speed difference between the straight travelling speed presumed by the first speed presuming portion and the straight traveling speed presumed by the second speed presuming portion and a failure judging portion which judges that a failure exists in the traveling function when the first straight travelling speed difference is equal to or more than the first straight travelling difference judging value.
