A variable capacity rotary compressor with upper and lower compression chambers having different capacities, the upper and lower compression chambers being partitioned from each other, and a rotary shaft extending through the upper and lower compression chambers. The rotary shaft includes a fixing hole and a latch pin which includes a head part is fixed to the rotary shaft through the fixing hole. The head part of the latch pin can be forcibly fit into a forcible fitting hole of the fixing hole. The head part is spaced apart from the inner circumference of the forcible fitting hole in the axial direction of the rotary shaft when the head part is forcibly fitted in the forcible fitting hole, so that a forcible fitting force is not applied in the axial direction of the rotary shaft.
