Zusammenfassung:	The present invention relates to a crank arm having an adjustable length, comprising: a power transmission bar coupled to a bicycle chain wheel; a length-adjustable body in which a slide groove is formed into which the power transmission bar is inserted; and a pressure fixing means that presses the length-adjustable body to adjust a coupling position of the power transmission bar and the length-adjustable body. Thus, the present invention can provide an assistive crank arm so that a user can obtain high propulsion force with little force. 본 발명은 자전거 체인 휠에 결합되는 동력전달 바와, 상기 동력전달 바가 끼워지는 슬라이드홈이 형성되는 길이조절 몸체와, 상기 길이조절 몸체를 압박하여 상기 동력전달 바와 상기 길이조절 몸체의 결합위치를 조절하는 압박고정수단을 포함하는, 길이조절이 가능한 크랭크암에 관한 것이다.
