To provide an engagement type clutch mechanism which enhances engagement probability, reduces backlash and has no restriction in rotation directions of a rotation member and a transmission member.SOLUTION: A first protrusion part 10 and an auxiliary protrusion part 11 are pressed and inserted to a recessed part 4b according to shaft direction movement to a rotation member side 4 of a second transmission member 17 by a second protrusion part 18, thereafter, the second protrusion part 18 can be inserted into the recessed part 4b so as to get in between the first protrusion part 10 and the auxiliary protrusion part 11 against energization force of energization means 13, and the first protrusion part 10 and the auxiliary protrusion part 11 can be moved together with the second protrusion part 18 by means of simple operation according to movement of only the second protrusion part 18. When the first protrusion part 10 and the auxiliary protrusion part 11 are inserted into the recessed part 4b at first, a gap G exists between the first protrusion part and the auxiliary protrusion part, and the recessed part 4b, therefore, engagement probability can be enhanced, thereafter, the gap G can be filled up by the second protrusion part 18 and, therefore, backlash can be reduced.SELECTED DRAWING: Figure 6 【課題】噛合い確率を向上させると共に、バックラッシュを低減し、更に回転部材及び伝動部材の回転方向の制限のない噛合い式クラッチ機構を提供する。【解決手段】第２伝動部材１７の回転部材側４への軸方向移動により第１凸部１０及び補助凸部１１を第２凸部１８で押圧して凹部４ｂに挿入した後、第２凸部１８を、付勢手段１３の付勢力に抗して第１凸部１０及び補助凸部１１間に入り込ませるように凹部４ｂ内に挿入でき、第２凸部１８のみの移動による簡易な操作で、第１凸部１０と補助凸部１１とを該第２凸部１８と一緒に移動させることができる。最初に第１凸部１０及び補助凸部１１を凹部４ｂに挿入する際は、凹部４ｂとの間に隙間Ｇが存在するので噛合い確率を高めることができ、その後、前記隙間Ｇを第２凸部１８で埋めることができるのでバックラッシュを低減できる【選択図】 図６
