PROBLEM TO BE SOLVED: To easily perform a fastening operation with bolts even in a place with poor workability such as a narrow place. SOLUTION: This fastening assisting structure comprises a bolt hole 60 allowing the thread part 32a of a bolt 32 to be passed therethrough, a seat face 58 allowing the heated seat face 32b of the bolt 32 to abut thereon, and a partition wall 64 vertically provided at the peripheral edge of the seat face 58 and guiding the bolt 32. A bolt inlet part 68 opening to the end part of the partition wall 64 is set flush with the surface 22a of the end part of a swelled part 22. Even when the bolt hole 60 is positioned at the rear of the swelled part 22, the bolt inlet part 68 is visible, and the bolt 32 can be inserted from the bolt inlet part 68. When the inner surface of the partition wall 64 is formed in a conical surface diverging toward the bottom thereof, the bolt 32 can be easily led into the bolt hole 60. COPYRIGHT: (C)2004,JPO |
