する。As described above, a small amount of operation in the step 15 of depressing the lock mechanism 3 of the caster 2 by the depressing operation means 7 is increased by the swing arm 11 and the eccentric cam 10 which constitute the speed increasing mechanism 6. As a result, the rotation shaft 4 can obtain a sufficient rotation amount to lock the lock mechanism 3, so that the operation becomes easy. Further, since the rotation of the rotation shaft 4 can be transmitted to all the casters 2, it is not necessary to individually lock the casters 2, so that it does not require any labor and operability. Is greatly improved.
