Abstract:
A stroller including in a grip portion thereof an operation mechanism for locking a folding operation and removing such locking,said operation mechanism comprising: a housing including: a space capable of storing a member therein; a lock lever disposed slidably in said housing; a securing pawl having a large thickness and disposed in the leading end portion of said lock lever; a lock removing lever disposed rotatably within said housing; a pressing portion formed in a portion of said lock removing lever and exposed externally of said housing; an operation portion formed in another portion of said lock removing lever and capable of pressing against said securing pawl; and a release wire securing portion disposed in a member formed integrally with said lock removing lever, when said lock lever is not allowed to slide, said securing pawl prevents said operation portion of said lock removing lever against rotation to thereby prevent the rotation of said pressing portion of said lock removing lever, so that said release wire securing portion is also prevented against rotation, and, if said lock lever is slid, said securing pawl is moved to thereby allow said operation portion of said lock removing lever to rotate, so that said pressing portion of said lock removing lever is allowed to rotate and thus said release wire securing portion is also allowed to rotate, a spring for normally energizing said lock lever to a locking position side, and, on a moving leading-end side of said securing pawl of said lock lever; and an extension portion formed projectingly within said housing and an engaging groove formed in the vicinity of a leading end of said extension portion, wherein if said lock lever is slid, then said securing pawl of said lock lever is moved to run up onto said extension portion and is thereafter engaged with said engaging groove and, if said pressing portion of said lock removing lever is further rotated, said securing pawl is moved by said spring to run up onto said extension portion again and is thereafter pulled back to the locking position side automatically.
