1. A cleaning device for a vehicular lamp comprising: a piston provided at a distal end thereof with a spray nozzle that sprays a cleaning fluid and a nozzle cover that forwardly covers the spray nozzle, and a cylinder that drives the piston to extend and refract with respect to an opening formed in a vehicle body; wherein said cleaning device further comprises: a bracket that is attached to the cylinder and positions the cylinder in the opening, a fixing member that is positioned on the bracket in an outwardly fitted manner, and an elastic member that is disposed between the bracket and the fixing member; and wherein the bracket has a pair of arm elements having engagement pieces that engage with front side of edge portions of the opening that are positioned mutually opposed, at least one of the pair of arm elements being an elastic arm element having elasticity in a direction of engagement and disengagement with respect to the edge portion of the opening, the fixing member has a plurality of contact portions, which are in contact with a rear side of the edge portion of the opening, and a deflection control portion, which prevents deflection of the elastic arm element in a direction of disengagement from the opening; and the engagement pieces of the bracket and the contact portions of the fixing member hold the edge portion of the opening, and the elastic member is provided between the bracket and the fixing member such that the fixing member is biased toward the opening in a state that the deflection total portion of the fixing member prevents deflection of the elastic arm element of the bracket.
