A razor handle comprising: a handle body comprising a head adapter and a grip portion extending from the head adapter; a connecting head configured to be coupled to a razor cartridge and coupled to the head adapter so as to be pivotable around a rotational axis, the connecting head comprising a head side cam surface on one side thereof; and a plunger disposed on one side of the handle body and comprising a plunger side cam surface configured to perform a cam action with the head side cam surface, the plunger being configured to provide, through the cam action, recovery force to restore the connecting head to a rest position, wherein the plunger comprises an elastic member and a cam action member having the plunger side cam surface formed on one side thereof, wherein a contact area between the head side cam surface and the plunger side cam surface is smaller when the connecting head is deviated from the rest position than when the connecting head is in the rest position, wherein the elastic member is elastically deformed to press the cam action member in a first direction, wherein, when the connecting head is in the rest position, the elastic member is elastically deformed to keep the cam action member pressed in the first direction, wherein the plunger further comprises a plunger housing, wherein the elastic member and at least a part of the cam action member are disposed inside the plunger housing, wherein the cam action member is pressed in the first direction by the elastic member to provide the recovery force to the connecting head, wherein the cam action member comprises a first protrusion and a second protrusion projecting from one side of the cam action member, wherein the plunger side cam surface comprises a first cam surface formed at one end of the first protrusion and a second cam surface formed at one end of the second protrusion, wherein, when the connecting head is in the rest position, the head side cam surface contacts both the first cam surface and the second cam surface, and wherein, when the connecting head is deviated from the rest position, the head side cam surface is in contact with only one of the first cam surface and the second cam surface. a handle body comprising a head adapter and a grip portion extending from the head adapter; a connecting head configured to be coupled to a razor cartridge and coupled to the head adapter so as to be pivotable around a rotational axis, the connecting head comprising a head side cam surface on one side thereof; and a plunger disposed on one side of the handle body and comprising a plunger side cam surface configured to perform a cam action with the head side cam surface, the plunger being configured to provide, through the cam action, recovery force to restore the connecting head to a rest position, wherein the plunger comprises an elastic member and a cam action member having the plunger side cam surface formed on one side thereof, wherein a contact area between the head side cam surface and the plunger side cam surface is smaller when the connecting head is deviated from the rest position than when the connecting head is in the rest position, wherein the elastic member is elastically deformed to press the cam action member in a first direction, wherein, when the connecting head is in the rest position, the elastic member is elastically deformed to keep the cam action member pressed in the first direction, wherein the plunger further comprises a plunger housing, wherein the elastic member and at least a part of the cam action member are disposed inside the plunger housing, wherein the cam action member is pressed in the first direction by the elastic member to provide the recovery force to the connecting head, wherein the cam action member comprises a first protrusion and a second protrusion projecting from one side of the cam action member, wherein the plunger side cam surface comprises a first cam surface formed at one end of the first protrusion and a second cam surface formed at one end of the second protrusion, wherein, when the connecting head is in the rest position, the head side cam surface contacts both the first cam surface and the second cam surface, and wherein, when the connecting head is deviated from the rest position, the head side cam surface is in contact with only one of the first cam surface and the second cam surface.
