1. A movable wall portion attachment mechanism of an incubator in which at least one wall portion of a plurality of wall portions attached to an incubator base so as to form an outer circumference of an infant accommodation space is attached as a movable wall portion to said incubator base,
wherein said movable wall portion is configured to pivot forward about a portion of a region including a lower end portion of said movable wall portion and a vicinity of said lower end portion of said movable wall portion from a substantially erect position to an outside of said infant accommodation space, wherein when said movable wall portion moves backward from an open state in a backward movement to a midway position, said movable wall portion moves backward to said midway position while abrupt backward movement is not substantially suppressed by damper means, wherein when said movable wall portion moves backward from said midway position in backward movement to a final backward moving position, said movable wall portion moves backward to said final backward moving position by an own weight while abrupt backward movement of said movable wall portion is suppressed by said damper means, wherein said movable wall portion is attached on said incubator base side through a support shaft portion so as to be configured to pivot forward and backward, and an axis of the support shaft portion is configured to move forward and backward in a substantially vertical direction relative to said incubator base, wherein said attachment mechanism further comprises a cam surface provided on said incubator base side, an impact attenuation portion provided on the cam surface and formed from an elastic body by a configuration in which said impact attenuation portion is provided on said incubator base side and constitutes a portion of said cam surface, and a cam surface abutment portion provided on said movable wall portion side, wherein said cam surface abutment portion is configured to abut against said incubator base side first at said impact attenuation portion when said movable wall portion is at a position, where said support shaft portion of said movable wall portion is lowered, and is made to pivot backward from a forward pivot position, wherein when said movable wall portion pivots forward, abrupt forward pivoting movement of said movable wall portion is suppressed by a second damper means, and wherein when said movable wall portion pivots backward, abrupt backward pivoting movement of said movable wall portion is not substantially suppressed by said second damper means. |
