ABSTRACT:
A cam device includes a first member including a recessed first engaging portion on an inner section, a recessed second engaging portion on an outer section, and recessed third and fourth engaging portions extending from the inner section to the outer section. Further, a second member includes a ridged first engaging portion on an inner section, a ridged second engaging portion on an outer section, and ridged third and fourth engaging portions extending from the inner section to the outer section. When the ridged first and second engaging portions are partially disposed in the recessed first and second engaging portions respectively, one contacted area between the ridged third engaging portion and the recessed third engaging portion plus another contacted area between the ridged fourth engaging portion and the recessed fourth engaging portion preclude the cam device from suffering an increased pressure.
