Trousers having an expansion/contraction device are provided to be manufactured simply, and to prevent deterioration in the function of an expansion/contraction member even if it is used for a long period of time. Trousers having an expansion/contraction device include a trouser body(11) and at least one expansion/contraction unit. A waist band portion(12) enclosing a user's waist is formed on the upper end portion of the trouser body. The expansion/contraction unit is installed on the waist band portion of the trouser body, and includes a length adjusting unit and expansion/contraction members. The length adjusting unit makes the waist band portion variable. The expansion/contraction members are fixed on both ends of the waist band portion on which the length adjusting unit is formed. |
