The invention discloses a vehicle speed sensor in flexible connection with a gearbox. The invention relates to a sensor, and specifically relates to the vehicle speed sensor in flexible connection with the gearbox. The invention solves problems that a conventional vehicle speed sensor is liable to lose efficacy and the cost is increased because the requirement for the machining precision of an interface of a sensor and the gearbox is high. The sensor comprises a front housing, a pin shaft assembly, a spring, a rolling ball, a printed board assembly, and a rear housing. The pin shaft assembly is inserted into the front housing. The other end of a pin shaft is fixedly connected with one end of a connection shaft, and the face of the other end of the connection shaft is provided with a circular hole. The interior of the circular hole is provided with a rolling ball and the spring is disposed the rolling ball and the bottom of the circular hole. An inner side of the rear end face of the rear housing is fixedly co
