Motor mounting structure and washing machine

The invention provides a motor mounting structure, a motor is hung on a motor bracket through a connecting rod, and an adjusting mechanism for adjusting the relative position is arranged between the connecting rod and the motor bracket; the adjusting mechanism comprises a supporting rod which sequentially penetrates through the connecting rod and the motor support, limiting parts which protrude out of the corresponding sides in the radial direction and penetrate out of the through holes are arranged at the two ends of the supporting rod, and at least one limiting part is connected with the supporting rod in an adjustable relative position mode. By means of the motor installation structure, disassembly-free adjustment of the motor installation position is achieved, the motor can move up and down on the installation position on the motor support through adjustment of the relative position of the limiting part, and therefore the remarkable technical progress that the tensioning degree of a belt connected with th
