  (1) Utilizing a Braid group action on a completion of U_q(\hat{sl_{n+1}}), an
algebra homomorphism from the toroidal algebra U_q(sl_{n+1,tor}) (n\ge 2) with
fixed parameter to a completion of U_q(\hat{gl_{n+1}}) is obtained.
  (2) The toroidal actions by Saito induces a level 0 U'_q(\hat{sl_{n+1}})
action on level 1 integrable highest weight modules of U_q(\hat{sl_{n+1}}).
Another level 0 U'_q(\hat{sl_{n+1}}) action is defined by Jimbo, et al., in the
case n=1. Using the fact that the intertwiners of U_q(\hat{sl_{n+1}}) modules
are intertwiners of toroidal modules for an appropriate comultiplication, the
relation between these two level 0 U'_q(\hat{sl_{n+1}}) actions is clarified.
