To secure a uniform tightening allowance over the entire periphery of a seal section while making a seal member mountable easily and preventing a mounting error, in a seal structure for the joint section between path forming members, configured in such a manner that a seal member is disposed between a first path forming member and a second path forming member, the seal member having a seal section mounted in an endless mounting groove provided in the surface of the first path forming member which is joined to the second path forming member.
The seal member 12 is configured so as to integrally have: the seal section 12a; ear sections 12b protruding side-ward along a joint surface 10 from the portions of the seal section 12a which are separated from each other in the peripheral direction; and protrusions 12c respectively protruding from the ear sections 12b in the direction opposite to a second path forming member 6 so as to be perpendicular to the joint surface 10. The joint surface 10 is provided with: recesses 21, which are continuous to the mounting groove 19 in such a way as to house the ear sections 12b, and press-fit holes 22, each having one end opened to the recess 21 by allowing the protrusion 12c to be press fitted therein.
