  • Patent number: 11885330
    Abstract: A lower end plate cover is provided with a bulging portion. In a circumferential direction of a rotary shaft, a plurality of bolt holes includes a first bolt hole arranged between a distal end portion and a proximal end portion of the lower discharge valve, a second bolt hole arranged in a position adjacent to the first bolt hole on a side close to a lower vane groove with respect to the first bolt hole, and a third bolt hole arranged in a position adjacent to the first bolt hole on a side away from the lower vane groove with respect to the first bolt hole. When the bulging portion is divided into a first bulging portion and a second bulging portion using a first straight line, the first bulging portion is larger than the second bulging portion.
