PROBLEM TO BE SOLVED: To allow housing a rot of electronic parts, although a housing case is small, by, one end part of a second housing groove channel communicated to a discharge opening, connecting the other end part of the first housing groove channel and the other end part of the second housing groove channel so that the movement of electronic parts which are to be housed is unidirectional. SOLUTION: One end part of a first housing groove channel 1a is communicated to an insert opening 7 formed at a case main body 2, while the other end part of a second housing groove channel 1b is communicated to a discharge opening 5 formed at the case main body 2. The other end parts of the first and the second housing groove channels 1a and 1b are so connected with a communication channel that movement of electronic parts 4 which are to be housed is unidirectional with a small radius of curvature. The other end parts of the first and the second housing groove channels 1a and 1b are so connected as formation in the same direction as the first and the second housing groove channels 1a and 1b, for example, counterclockwise. The first and second housing groove channels 1a and 1b are formed almost entirely with a minimum required space of the case main body 2, resulting in reduced size of the case main body 2. |
