<p>A shock-absorbing device includes a first crank member (30), a buffering unit (40) and a second crank member (50). The first crank member (30) has a first hole (32) formed therein. The buffering unit (40) is inserted into the first hole (32), and has a cylindrical hollow outer wall (43), a cylindrical hollow inner wall (42) coaxially mounted in the outer wall (43), an annular rubber cushion (44) disposed between the inner and outer walls (42, 43), and a shaft (46) extending through and engaging the inner wall (42). The outer wall (43) engaging the first crank member (30). The second crank member (50) is connected to and is rotatable about and together with the shaft (46). The rubber cushion (44) is deformed by the outer and inner walls (43, 42) in order to retard pivotal movement of the first crank member (30) relative to the second crank member (50) about the shaft (46). <IMAGE></p> |
