A device for preventing slipping of a vehicle is disclosed, which improves a vehicle slipping prevention device in which a plurality of spikes connected with a connection member are inserted into a gap between double wheels disposed at a rear side of a large size vehicle at regular intervals for preventing slipping. In the present invention, a structure contacting with a tire surface along with a spike is newly improved, and a structure of an engaging member used for maintaining the tensional force of a plurality of spikes connected by means of a connection member is newly improved. It is possible to achieve a fast and simple engaging and disengaging work and to keep a substantial tensional force so that a vehicle slipping prevention device is not disengaged even during a long time drive of a vehicle.

1. A vehicle slipping prevention device, comprising: a plurality of spikes 10 formed of an insertion member 12 of which an intermediate portion is V-shaped for being inserted into a space formed between double wheels 16 and a close contact member 14 which is flat-contacted with both sides of the insertion member 12 for a close contact with the surface of each tire of the double wheels 16; a connection means 30 which connects the insertion member 12 of the spikes 10; and,an engaging member which engages both ends of the connection means 30; wherein said engaging member 700 includes: an engaging member 701 which has an engaging hook member 701b of which one end is formed of an insertion member 701a, and the other end is connected to the connection means 30, with a plurality of engaging holes 701c being formed between the engaging hook member 701b and the insertion member 701a in a row;an engaging body 702 which has a bottom piece 702b formed of an engaging hook member 702a connected with the connection means 30 at one end in a U shape so that the insertion member 701a of the engaging member 701 is inserted, a fixing pin hole 702d for engaging a fixing pin 702c with respect to the engaging hook member 702a at both sides of the bottom piece 702b, a body 702g in which rotation pin holes 702f engaged with a rotation pin 702e are sequentially formed on a wall plate 702g′, and an engaging piece 702j which is fixed at an upper side of the rotation pin 702e and is connected with a tensional spring 702h connected with the fixing pin 702c and performs a rotation and return operation, and is formed of an engaging member 702i which is downwardly protruded for an engagement by the engaging hole 701c; and a connection ring 703 which is provided at each end of the connection means 30 for connecting the engaging hook member 701b of the engaging member 701 and the engaging hook member 702a of the engaging body 702. 2. The device of claim 1, further comprising an auxiliary engaging member 800 in which a connecting ring 801 is engaged to the connection means 30 in a backward direction of the spike 10 positioned at both sides of the engaging member 700 for preventing a loosening phenomenon of the engaging member 700, with the auxiliary engaging member 800 being formed of a contractive band 803 having a separable hook 802 at both ends for a connection to the connection ring 801. 3. The device of claim 1, wherein said connection means 30 is formed of a belt 32 and is fixed by a method of using a rivet 11d for an engagement with the spike 10 having a friction rubber pad 11a.
