PROBLEM TO BE SOLVED: To provide a housing for an optical device capable of securely sealing the inside and preventing deterioration in properties of the optical device.SOLUTION: The housing for an optical device includes: a container portion 30 for storing an optical device 10 connected to optical fiber 11 while leading out the optical fiber 11 extending in a front-to-back direction, having side surfaces standing upward around a bottom surface 5 below, and including a slit 34 extending upward from below and opening upward, formed at one of front and rear side surfaces; a box-shaped lid member 20 opening downward, having a slit 24 extending downward from above and opening downward; and a tongue plate member 41 installed inside the container portion 30. The lid member 20 is fitted from the outside of the container portion 30, covering the whole side surfaces of the container portion 30. The slit 24 and the slit 34 form a rectangular opening for causing the inside and the outside of a housing 1a to communicate with each other, and leading out the optical fiber 11. The plate member 41 includes a slit 42 having such a width as to be in contact with the periphery of the optical fiber 11, and the plate member abuts an inner surface around the slit 24.SELECTED DRAWING: Figure 4 |
