PROBLEM TO BE SOLVED: To enable a synthetic resin material block and a nut to be positively fixed to each other.SOLUTION: A block 2 is fitted into a block fixing hole 11 under an operation in which groove side walls 18 of first and second operation parts 15 are resiliently deformed in a direction where a groove width of a cut-groove 16 is decreased and flange protrusions 21 of the first and second operation parts 15 are displaced more inwardly than that of an inner peripheral surface of the block fixing hole 11. The block 2 is fixed in the block fixing hole 11 of a nut 7 under an operation in which when the flange protrusions 21 are moved in the block fixing hole 11 up to a position where it oppositely faces against block fixing grooves 13, the first and second operation parts 15 are resiliently recovered, and the flange protrusions 21 of the first and second operation parts 15 are fitted into the block fixing grooves 13. The block 2 is made in such a manner that the outer peripheral surface side wall parts 20 of the first and second operation parts 15 in which the flange protrusions 21 are formed are formed in arch shape. In addition, when a force for pushing out the block 2 outward of the block fixing hole 11 is acted under a state in which the block 2 is fixed in the block fixing hole 11, a force for pushing the flange protrusions 21 of the first and second operation parts 15 into the block fixing grooves 13 is acted.SELECTED DRAWING: Figure 1 |
