Abstract
A biological cell observing chamber (), wherein an intermediate support body () forming a skeleton outer shell structural part is mounted on a bottom support body () and a cover block body () is mounted on the bottom support body () on which the intermediate support body () is mounted by using lever mechanisms () and () incorporating a cam mechanism and a clamp mechanism so that the contact faces thereof can be pressed against each other in the vertical direction. The cam mechanism comprises cam grooves () and () formed in both leg part inner surfaces of U-shaped levers () and () rotatably supported on the bottom support body () and pins () and () slidably moving in the cam grooves and built in the outer peripheral surfaces of the intermediate support body () and the cover block body () at corresponding two points. Thus, in the biological cell observing chamber used for the detection of cell chemotaxis and chemotactic cell separator, the assembly and disassembly operations for the intermediate support body forming the skeleton outer shell structural part and the cover block body can be facilitated, and the operability of the chamber can be increased.
