An organic silicon compound represented by formula (1) makes it possible to significantly lower the hysteresis loss of a cured product when added to a rubber composition and also imparts a rubber composition with which it is possible to realize a desired low-fuel-consumption tire. (In the formula, R 1 independently represent a C1-10 alkyl group or C6-10 aryl group, R 2 independently represent a C1-10 alkyl group or C6-10 aryl group, f represents a number of 0 or higher, e and g independently represent a number greater than 0, and m represents an integer of 1-3. However, the order of each of the repeating units is arbitrary.) |
