Abstract
A return pipe is constituted by combining a pair of return pipe halves split along a non-load passage. A pipe hold down member is fixed to a nut member so as to be astride the return pipe, fixing the return pipe to the nut member. A flange portion is formed on each of the return pipe halves, while a pair of fixing leg portions covering the flange portion of each return pipe half is formed on the pipe hold down member. Fastening members pass through the fixing leg portions of the pipe hold down member and the flange portion of the return pipe halves and are fastened to the nut member. When the fixing leg portions of the pipe hold down member are fixed to the nut member by the fastening members, an engagement portion of the pipe hold down member is configured to tighten the pair of the return pipe halves in the direction where split faces of the return pipe halves abut against each other.
