The invention claimed is: 1. A cylinder housing of an actuator for lifting a bonnet hood in the event of a collision, wherein the actuator includes the cylinder housing fixed to a vehicle body of a vehicle and extending in a center axis line direction, a piston portion accommodated in the cylinder housing to be slidable, a rod portion extending forward in a sliding direction of the piston portion from the piston portion and protruding from the cylinder housing, and a drive source of the actuator, wherein the cylinder housing includes a cylindrical cylinder portion extending in the center axis line direction, and a bent portion bent with respect to the cylinder portion and extending inward in a radial direction from an end portion of the cylinder portion, wherein the cylinder portion includes a first cylinder portion, and a second cylinder portion which is located on the side of the bent portion in the first cylinder portion and is connected to the bent portion, wherein a thickness of the second cylinder portion is equal to or larger than a thickness of the first cylinder portion, and wherein a thickness of the bent portion is larger than the thickness of the first cylinder portion, wherein the thickness of the second cylinder portion is larger than the thickness of the first cylinder portion, and wherein a length of the second cylinder portion in the center axis line direction is equal to or larger than an outer diameter of the second cylinder portion. 2. An actuator for lifting a bonnet hood in the event of a collision, comprising: a cylinder housing fixed to a vehicle body of a vehicle and extending in a center axis line direction; a piston portion accommodated in the cylinder housing to be slidable; a rod portion extending forward in a sliding direction of the piston portion from the piston portion and protruding from the cylinder housing; and a drive source of the actuator, wherein the cylinder housing includes a cylindrical cylinder portion extending in the center axis line direction, and a bent portion bent with respect to the cylinder portion and extending inward in a radial direction from an end portion of the cylinder portion, wherein the cylinder portion includes a first cylinder portion, and a second cylinder portion which is located on the side of the bent portion in the first cylinder portion and is connected to the bent portion, wherein a thickness of the second cylinder portion is equal to or larger than a thickness of the first cylinder portion, and wherein a thickness of the bent portion is larger than the thickness of the first cylinder portion, wherein the thickness of the second cylinder portion is larger than the thickness of the first cylinder portion, and wherein a length of the second cylinder portion in the center axis line direction is equal to or larger than an outer diameter of the second cylinder portion.
