Abstract: A hose clamp includes a clamp main body including a ring portion and a pair of knob portions; and a holder. The holder includes a main body portion, a pair of holding walls, and an operation portion. An inner surface on a distal end side of one holding wall includes a protrusion that protrudes more largely inward than an inner surface on a distal end side of other holding wall. And in a state where the pair of knob portions are close to each other, a distal end of one knob portion in a peripheral direction is engaged with the inner surface of the one holding wall, and the other knob portion is engaged with the inner surface of the other holding wall, so that the ring portion is kept in a diameter-increased state.

Abstract: A valve case mounting structure includes a mount base and a valve case. The mount base includes a valve case support portion and a retainer piece having a first engagement opening and a second engagement opening. The valve case includes an engaging projection portion, and a holder portion. When the engaging projection portion is positioned at a front end side of the first engagement opening, the retainer piece does not reach the holder portion. When the engaging projection portion is moved from the front end side of the first engagement opening toward the second engagement opening, a front end portion of the retainer piece is inserted into the holding space before becoming unable to be inserted into the holder portion.
