PROBLEM TO BE SOLVED: To provide a support structure for a suspension device excellent in lubricating performance of a supporting bearing and improved in durability. SOLUTION: The support structure for the suspension device is constructed from a double-axle suspension. An upper rotation mechanism 4 of the support structure has an upper pivot shaft 29 detachably joined to a vehicle body-side knuckle 2 by a fixation bolt 28 and also has an upper support bearing 30 installed between the upper pivot shaft 29 and a wheel-side knuckle 1. The upper support bearing 30 is a back-to-back mounted full complement roller-type double-row tapered roller bearing having, formed on its inner periphery, tapered double-row outer rolling surfaces 31a, a pair of inner rings 33 having, formed on its outer periphery, tapered inner rolling surfaces 33a facing the double-row outer rolling surfaces 31a, and double-row tapered rollers 32 rollably received between the rolling surfaces. The upper support bearing 30 is filled with a solid lubricating agent 37. Accordingly, the deviation of grease can be prevented, and sufficient lubricating performance can be exhibited.
