To provide a drive switching device for a handcart capable of facilitating switching of the presence of a drive device and to provide a handcart having the drive switching device.SOLUTION: A drive switching device 10 includes a fitting part 22, a first rotating shaft 24, a second rotating shaft 26, a first link member 28, a second link member 30, a drive device 32 and a drive wheel 34. The first link member 28 is constituted of a plate body. The first link member 28 is rotatably mounted on the first rotating shaft 24. The second link member 30 shown in Fig.5 is constituted of a link body. The second link member 30 is rotatably mounted on the second rotating shaft 26. When protruding parts 38, 42, 48, 52 are engaged with recessed parts 40, 44, 46, 50 at the same time, the first link member 28 and the second link member 30 are relatively fixed and thus the rotation of each of the link members 28, 30 is stopped. The first link member 28 and the second link member 30 are relatively fixed, thus fixing a position of the drive wheel 34.SELECTED DRAWING: Figure 1 【課題】駆動装置の有無の切り替えが簡単にできる手押し車の駆動切替装置およびその駆動切替装置を備えた手押し車を提供する。【解決手段】駆動切替装置１０は、取り付け部２２、第１回転軸２４、第２回転軸２６、第１リンク部材２８、第２リンク部材３０、駆動装置３２および駆動輪３４を備える。第１リンク部材２８は板体で構成されている。第１リンク部材２８は第１回転軸２４に回転可能に取り付けられている。図５に示す第２リンク部材３０は板体で構成されている。第２リンク部材３０は第２回転軸２６に回転可能に取り付けられている。凸部３８、４２、４８、５２が凹部４０、４４、４６、５０に同時に嵌った時、第１リンク部材２８と第２リンク部材３０が相対的に固定され、それぞれのリンク部材２８、３０の回転が停止される。第１リンク部材２８と第２リンク部材３０が相対的に固定されることで、駆動輪３４の位置が固定できる。【選択図】図１
