PROBLEM TO BE SOLVED: To provide a dog clutch device capable of increasing a binding force of dog teeth to each other by a simple configuration.SOLUTION: A dog clutch device of this invention comprises: a movable ring 50 having an inner peripheral surface opposing against an outer peripheral surface of a hub 40 and having dog teeth D1, D2; a supporting mechanism for supporting the movable ring 50 in such a way that it can be moved in an axial direction and integrally in respect to the hub 40. A gear change has dog teeth D3, D4 oppositely facing against the dog teeth D1, D2. The supporting mechanism has a guide groove 41 extending in an axial direction at an outer peripheral surface of the hub 40 and a guide pin 51 protruded from the inner peripheral surface of the movable ring 50, engaged with the guide groove 41 and movable from its neutral position to an in-gear position. Side surfaces 42, 43 of the guide groove 41 have slant portions 42b, 43b that are inclined in respect to a virtual line CL3 in parallel with the axis line and extended toward the end part in an axial direction.SELECTED DRAWING: Figure 5 【課題】簡易な構成によりドグ歯同士の結合力を高めることができるドグクラッチ装置を提供する。【解決手段】ドグクラッチ装置は、ハブ４０の外周面に対向した内周面を有するとともに、ドグ歯Ｄ１，Ｄ２を有する可動リング５０と、ハブ４０に対し軸方向に相対移動可能かつ一体に回転可能に可動リング５０を支持する支持機構とを備え、変速ギヤは、ドグ歯Ｄ１，Ｄ２に対向したドグ歯Ｄ３，Ｄ４を有する。支持機構は、ハブ４０の外周面に軸方向に延設されたガイド溝４１と、可動リング５０の内周面から突設され、ガイド溝４１に係合して中立位置からインギヤ位置にかけて移動可能なガイドピン５１とを有する。ガイド溝４１の側面４２，４３は、軸線と平行な仮想線ＣＬ３に対し傾斜して軸方向端部にかけて延在する傾斜部４２ｂ，４３ｂを有する。【選択図】図５
