To solve a problem that there is not a strap capable of being worn to various pumps capable of responding to individual differences even if a foot girth of an instep of a foot significantly varies depending on an individual and even if a thickness and a height of a heel vary depending on a pump, and not causing forward slippage of the foot inside the pump.

A strap belt for a pump includes: a grasp part abutting on a rear part of a pump, for grasping the pump; a holding part integrally continuously connected to the grasp part, and forming an annular part for inserting a heel of the pump through it together with the grasp part; and a fixture extended from a continuous connection part between the grasp part and the holding part.
