FRAME MOUNTING STRUCTURE FOR COMBINING EASILY A MOVABLE NUT BY RESTRICTING THE ROTATION OF THE NUT WITH A GUIDE BRACKET AND A LONG BOLT PENETRATING A LOWER RUBBER, A FRAME, AN UPPER RUBBER, AND A MEMBER FROM THE LOWER SIDE TO THE UPPER SIDE IN ORDER

摘要

PURPOSE: A frame mounting structure is provided to reduce the number of parts by embedding and combining a movable nut and a guide bracket in a vehicle body member without a plug, to shorten the mounting time, and to secure firm combination. CONSTITUTION: A frame mounting structure is composed of a vehicle frame; upper and lower rubbers(13,12) inserted into the upper and lower ends of the frame; a member(15) integrated with a floor panel(16) fitted to the upper end of the upper rubber; a through-bolt and a nut combined to each other; a plug inserted into the floor panel; a long bolt(30) passing through a lower plate(11), the lower rubber, the frame, the upper rubber, an upper plate(14), the member, and the floor panel from the upper side in order; a rod-shaped inner pipe(31) for covering the outer peripheral surface of the long bo a guide bracket(40) formed with a guide hole(41) on the upper plate and welded from the inside of the member; and a movable nut(50) embedded to interlock in the guide hole of the guide bracket. The movable nut is firmly combined with the long bolt with rotating the long bolt. The rotation of the movable nut is restricted by the guide bracket.
