AUTONOMOUS TRAVEL TYPE CLEANER

To reduce breakage of an autonomous travel type cleaner.SOLUTION: An autonomous travel type cleaner includes: a housing; drive wheels 20 for moving the housing; wheel support members 21 for supporting the drive wheels 20 to be vertically movable with respect to the housing; and lifting parts for lifting up a front part or a rear part of the housing. Each one of the lifting parts is rotatably supported by the housing, and includes a cam 90 for pressing the wheel support member 21 by rotation so as to lift up the front part or the rear part of the housing. When downward force is applied from above the housing during lifting-up the front part or the rear part of the housing, the cam 90 is rotated to return to the original state.SELECTED DRAWING: Figure 20 【課題】自律走行型掃除機の破損を低減させる。【解決手段】自律走行型掃除機は、筐体と、筐体を移動させるための駆動輪２０と、駆動輪２０を筐体に対して上下方向に可動に支持する車輪支持部材２１と、筐体の前方又は後方を持ち上げる持上げ部と、を備える。持上げ部は、筐体に回転可能に支持され、回転することにより車輪支持部材２１を押して筐体の前方又は後方を持ち上げるカム９０を含む。筐体の前方又は後方が持ち上げられているときに筐体の上方から下向きの力が印加された場合、カム９０が元に戻る方向へ回転するように構成される。【選択図】図２０
