(57) [Problem] To provide a housing seal structure capable of reliably preventing water from infiltrating into a housing. SOLUTION: A packing 23 is provided with a groove 25 having a rectangular cross section perpendicular to the annular extending direction along the annular extending direction of the packing 23 itself. The wall 21 is attached to the wall 21 such that the wall 21 is fitted into the groove 25. That is, the packing 23 Are the tip surface 21a and both side surfaces 21b, 21c of the wall 21. Is attached to the wall 21 so as to cover the wall. Accordingly, the cross-sectional shape of the packing 23 itself perpendicular to the annular extending direction is substantially U-shaped. In particular, an outer convex portion 2 protruding outward is provided on a side portion 23b outside (upper side in the figure) of the packing 23. 7 is provided, and the outer convex portion is formed in an annular shape so as to make a round around the outer side portion 23 b of the packing 23. |
