 a main body rockably supported by the boom; and 
 a grounding part that is rockable with respect to the main body and is in contact with a ground when supporting the front loader, and 
   a rocking shaft of the grounding part is movable to an engagement position capable of engaging with the boom and a release position capable of releasing the engagement with the boom by moving with respect to the main body.   
     
     
         7 . The front loader according to  claim 6 , wherein
 the stand further includes a biasing part that biases the grounding part such that the grounding part rocks in one direction in a rocking direction and the rocking shaft of the grounding part moves toward the engagement position.   
     
     
         8 . The front loader according to any one of  claims 1 to 7 , wherein
