PROBLEM TO BE SOLVED: To facilitate insertion and removal to/from a holder without deformation of a periphery of an engagement part to an outer side in forming the lock piece because stress generated by forcible removal of a die is absorbed in a periphery of an engagement projection part.SOLUTION: The lock piece 1 includes: a pair of side walls 12a, 12b opposite to each other; and a connection wall 13 crossing over the pair of side walls 12a, 12b, and is formed so that a cross sectional shape is an approximately inverted U-shape. An engaged part 11 having grooves 11g and projections 11p alternately arranged over an entire length of an axial direction X is formed on an inner surface side IS of the pair of side walls 12a, 12b and the connecting wall 13 so as to engage with an engagement part 31 of a rod 3. The engagement projection part P projecting from the inner surface side IS of the one of the side walls 12a, 12b to the other opposite side walls 12a, 12b is formed on the engaged part 11 except for an end part 11e in the axial direction X of the engaged part 11. |
