<P>PROBLEM TO BE SOLVED: To provide a spring mounting structure having excellent assembling workability and assembling strength in a spring stopper mechanism 70 to stop a spring of a pressure regulating valve 50 of a cap. <P>SOLUTION: A spring stopper mechanism 70 includes stopper holding parts 71 that are formed along an inner peripheral part of a valve chest formation-member 20b, and a spring support member 75 that is held by the stopper holding parts 71 and supports an upper end of the spring. The spring support member 75 is pressed down in an axial direction of a fuel cap against a pressing force of a first spring 68. The spring support member 75 at the pressed-down position is rotated relative to the stopper holding parts 71 by a preset angle, and is then pressed against the stopper holding parts 71 by the pressing force of the spring and is held by engagement parts 77. <P>COPYRIGHT: (C)2006,JPO&NCIPI |
