PROBLEM TO BE SOLVED: To provide a tooth fixing member capable of improving durability of an elastic pin equipped with a highly rigid engaging part and an elastic member.SOLUTION: A tooth fixing member has an elastic pin 8 and a lock pin 9. The elastic pin 8 has a columnar member 81 and an elastic member 83. The columnar member 8 has a pair of long faces and a pair of non-long end faces connecting the pair of long faces. A first engaging part is formed on one long face of the columnar member 8. The lock pin 9 has a second engaging part that engages with the first engaging part of the columnar member 8. The elastic pin 8 is fixed to an insertion hole formed by fitting an adapter and a tooth member. The lock pin 9 is also fixed to the insertion hole to which the elastic pin 8 is fixed. A projection part is formed on each of the pair of end faces of the columnar member 8 at its end part distant from one long face. The elastic member 83 is disposed as a compressive deformation part on one long face side of the projection part.SELECTED DRAWING: Figure 6 |
