The invention discloses a support assembly, which is used for supporting a rotatable shaft body, and comprises a support, a bearing seat, a supporting part and a supporting part, the bearing comprises a bearing outer ring and a bearing inner ring; the two dust covers are used for being arranged outside the shaft body in a sleeving mode and located on the two sides of the bearing respectively. The sealing element comprises a framework and an oil seal arranged on the framework, and the oil seal is used for sealing the oil storage cavity; the dustproof cover comprises an annular connecting section, an inner flange and an outer flange, the outer flange extends towards the support and is in clearance fit with the support, a first water blocking cavity is formed between the outer flange and the inner flange, and a second water blocking cavity is formed between the inner flange and the framework. The invention further discloses a transmission shaft connecting structure comprising the support assembly, a transmission shaft comprising the transmission shaft connecting structure and an automobile comprising the transmission shaft. By applying the support assembly, the overall service life of the support assembly can be prolonged while the sealing requirement is met so as to be matched with the service life of an existing transmission shaft, and maintenance-free is achieved.
