Description

The present invention relates to a floor joint device that covers a joint portion between left and right floor frames capable of running a vehicle.

Conventionally, a floor joint device on which a vehicle can travel has a joint plate support recessed portion formed in one joint portion side floor housing of the left and right floor housings, and the other joint portion side floor housing corresponding to the joint plate support recessed portion. The formed anti-joint side is an inclined joint plate slide support recess, a joint plate attached so as to cover the joint plate slide support recess and the joint plate support recess, and the tip of the joint plate is vertically oriented A locking pin insertion case formed at a position near both sides of the rear end portion of the joint plate movably, and an anchor fixed to the floor frame of the joint plate support recess inserted into the locking pin insertion case It was comprised with the attachment means which consists of a stop pin.

For this reason, if the bottom surface of the joint plate and the joint plate support concave portion or joint plate slide support concave portion are not flat, there is a drawback that the vehicle is rattled and noise is generated when the vehicle runs on the joint plate.
