PROBLEM TO BE SOLVED: To provide a new organosilicon compound giving a silica-compounded vulcanizable rubber composition improved in properties including low heat generation tendency and resilience through being compounded as a compounding agent for rubber, to provide a method for producing the organosilicon compound, and to provide such a compounding agent for rubber using the organosilicon compound. SOLUTION: The organosilicon compound is represented by the average compositional formula (1) (wherein, R<SP>1</SP>and R<SP>2</SP>are each a 1-4C monovalent hydrocarbon group; R<SP>3</SP>is a 1-18C monovalent hydrocarbon group; R<SP>4</SP>and R<SP>5</SP>are each a 1-15C bivalent hydrocarbon group; m is a positive number of 1-4 on average; n is a positive number of 2-4 on average; q is a positive number of 0-3; u is 0 or 1; and p is 0, 1 or 2, s and t are each a positive number of 0-3, wherein s and t are not 0 at the same time, and (p+s) and (p+t) are each a positive number, however, (p+s) and (p+t) are not 3 at the same time ).
