A reinforcing apparatus for a housing of a bar-type mobile phone is provided to allow the housing to bend and straighten. The mobile phone includes a first housing having a liquid crystal display and a second housing having a key pad. The apparatus includes a first reinforcing member in the first housing, a second reinforcing member in the second housing, and a reinforcing connector that couples the first and second reinforcing members to each other and connects the first and second housings so that they may be bent or straightened with respect to one another. This configuration minimizes damage caused by dropping the phone.
