The terminal includes a body section and a terminal rod inserted through the body section. The terminal guard is provided outside the casing to surround the terminal. The terminal guard includes a side wall facing the terminal rod in a radial direction. The insulating member is disposed inside the terminal guard. The insulating member includes a bottom section covering an area around the body section, and a side section integrally provided in an erected manner on a peripheral edge portion of the bottom section. The side section covers an inner surface of the side wall of the terminal guard. ## Claims ### Claim 1 A compressor comprising: a casing; a terminal provided to the casing, the terminal including a body section and a terminal rod inserted through the body section; a terminal guard provided outside the casing to surround the terminal, the terminal guard containing metal and including a side wall facing the terminal rod in a radial direction; and an insulating member disposed inside the terminal guard, the insulating member including a bottom section covering an area around the body section, and a side section integrally provided in an erected manner on a peripheral edge portion of the bottom section, the side section covering an inner surface of the side wall of the terminal guard. ### Claim 2 (depends on 1) The compressor according to claim 1, wherein a terminal chamber is defined by the casing and the terminal guard, 90% or more of a surface area of a metal portion that faces the terminal chamber is covered with the insulating member. ### Claim 3 (depends on 1) The compressor according to claim 1, wherein a height of the side section of the insulating member is substantially identical to a height of the side wall of the terminal guard. ### Claim 4 (depends on 1) The compressor according to claim 1, wherein the terminal guard includes a bottom plate in which a through hole is formed, and the body section is inserted through the through hole. ### Claim 5 A compressor comprising: a casing; a terminal provided to the casing, the terminal including a body section and a terminal rod inserted through the body section; a terminal guard provided outside the casing to surround the terminal, the terminal guard including a side wall facing the terminal rod in a radial direction; and an insulating member disposed inside the terminal guard, the insulating member including a bottom section covering an area around the body section, and a side section integrally provided in an erected manner on a peripheral edge portion of the bottom section the side section covering an inner surface of the side wall of the terminal guard, a height of the side section of the insulating member being substantially identical to a height of the side wall of the terminal guard. ### Claim 6 (depends on 5) The compressor according to claim 5, wherein a terminal chamber is defined by the casing and the terminal guard, 90% or more of a surface area of a metal portion that faces the terminal chamber is covered with the insulating member. ### Claim 7 (depends on 5) The compressor according to claim 5, wherein the terminal guard includes a bottom plate in which a through hole is formed, and the body section is inserted through the through hole. ### Claim 8 A compressor comprising: a casing; a terminal provided to the casing, the terminal including a body section and a terminal rod inserted through the body section; a terminal guard provided outside the casing to surround the terminal, the terminal guard including a side wall facing the terminal rod in a radial direction; and an insulating member disposed inside the terminal guard, the insulating member including a bottom section covering an area around the body section, and a side section integrally provided in an erected manner on a peripheral edge portion of the bottom section, the side section covering an inner surface of the side wall of the terminal guard, the terminal rod being inserted through a through hole, and the through hole is formed in the body section, an insulating glass portion containing glass being provided between an outer peripheral surface of the terminal rod and an inner peripheral surface of the through hole, the bottom section of the insulating member having, a through hole, the terminal rod being inserted through the through hole of the bottom section, and the bottom section covering the body section, and a diameter of the through hole in the bottom section of the insulating member being substantially identical to a diameter of the insulating glass portion. ### Claim 9 (depends on 8) The compressor according to claim 8, wherein a height of the side section of the insulating member is substantially identical to a height of the side wall of the terminal guard. ### Claim 10 (depends on 8) The compressor according to claim 8, wherein a terminal chamber is defined by the casing and the terminal guard, 90% or more of a surface area of a metal portion that faces the terminal chamber is covered with the insulating member.
