PURPOSE:To effectively convert reciprocating force to revolving force or vice versa by moderating an angle at which a crank is to be mooed suitable with respect to a connecting rod by the use of a bendable arm. CONSTITUTION:Rollers or gears which are formed on an arm are turned to bend the arm so that an angle between a connecting rod and the revolving direction of a crank pin is moderated suitably for transmitting reciprocating movement force to a crank. When the force of revolving motion is converted to the force of reciprocating motion, the conversion can be effectively performed by turning a crankshaft-side arm. The force of reciprocating motion and the force of revolving motion can be efficiently converted to each other.
