To achieve weight saving with a simple structure, and to increase a cabin space while reducing a cost of manufacture.SOLUTION: A wheel steering gear comprises: a rear suspension mechanism 12 including a knuckle member 30 which rotatably holds a right rear wheel W; rotatably supported first cam 14 and second cam 16; a first cam follower 18 which performs tracking motion along the first cam 14; a second cam follower 20 which performs tracking motion along the second cam 16; cam grooves 48, 48 provided on the first cam 14 and the second cam 16 respectively; first engaging pin 44 and second engaging pin 52 which are engaged with respective cam grooves 48; and a rotational driving force transmission member 24 which transmits a rotational driving force of an electric motor 22 to the first cam 14 and the second cam 16. The first cam 14 and the first cam follower 18 are located forward in a vehicle longitudinal direction on the basis of an axle 34, and the second cam 16 and the second cam follower 20 are located backward in the vehicle longitudinal direction on the basis of the axle 34.SELECTED DRAWING: Figure 1
【課題】簡素な構造で軽量化を図り、製造コストを低減すると共に、車室スペースを増大させること。【解決手段】右後輪Wを回転自在に保持するナックル部材30を含むリヤサスペンション機構12と、回転可能に支持される第1カム14及び第2カム16と、第1カム14に沿って追従動作する第1カムフォロワ18と、第2カム16に沿って追従動作する第2カムフォロワ20と、第1カム14及び第2カム16にそれぞれ設けられるカム溝48、48と、各カム溝48に係合する第1係合ピン44及び第2係合ピン52と、電動モータ22の回転駆動力を第1カム14及び第2カム16に対して伝達する回転駆動力伝達部材24とを備え、第1カム14及び第1カムフォロワ18は、車軸34を基準として車両前後方向の前方に配置され、第2カム16及び第2カムフォロワ20は、車軸34を基準として車両前後方向の後方に配置されている。【選択図】図1
