PROBLEM TO BE SOLVED: To provide a hanging hook capable of facilitating assembly of an upper hook piece to a lower hook piece without increasing the shaft length of a joint part or decline of the engagement power between joint parts. SOLUTION: The joint part 13 of the lower hook piece 11 has a butt surface 14, a shaft part 16 composed of divided pieces 16a and 16b, and a locking pawl 18 extending outward in the radial direction from front ends of the divided pieces 16a and 16b. The joint part 12 of the upper hook piece 10 has a butt surface 20, a shaft hole 22, a receiving space 23 for receiving the locking pawl 18, and an annular restraining wall 25 facing the receiving space 23 for permitting sliding of the locking pawl 18 in the direction of rotation while restraining the locking pawl 18 from loosening from the shaft hole 22. The joint part 13 of the lower hook piece 11 has a recess part 19 continued to a slit 17 of the shaft part 16 and recessed deeper than the butt surface 14. COPYRIGHT: (C)2009,JPO&INPIT
