Some of these are disclosed in Japanese Utility Model Publication No. 13064 and Japanese Utility Model Application Publication No. 54-37666.

ル部の盗難に遭うことが多発していた。(Problem that the invention aims to solve) In the saddles of modern rental bicycles, the saddles are frequently adjusted up and down according to the height of the user, so sometimes the up and down adjustment of the saddle is the limit of the seat post. If you cross the line, there is a risk of accidents such as bending or breaking the seat post, and because the quick seat pin can be adjusted up and down while the bike is parked, the seat post and the saddle part may be stolen. Things were happening frequently.

ていた。 For this reason, the devices shown in the above-mentioned Japanese Utility Model Publication No. 52-13064 and Japanese Utility Model Application No. 54-37666 have been proposed, but these devices are complex, difficult to set up, and stolen. Each of them had problems such as being easily removed.

シートポストを立パイプに対して左右に回転させ
ることができないという問題点があつた。 Furthermore, with conventional screw-type quick-tightening bolt structures, general users do not know how much to tighten them, so they often end up tightening them more than necessary. For this reason, if the fitting portion between the upright pulp and the seat post is deformed, or if the upright pipe is not completely restored even after loosening the screw, the seat post cannot be adjusted up and down smoothly. If the seat post becomes difficult to slide against the vertical pipe, there is a method to move the saddle and seat post up and down while rotating them from side to side relative to the vertical pipe, but this method was proposed by the applicant earlier. In the case of No. 61-69898, there is not enough room in the width of the stopper relative to the width of the recessed groove.
There was a problem that the seat post could not be rotated left and right with respect to the vertical pipe.

あるという問題点があつた。 In addition, with conventional fastening devices using bolts and nuts, when tightening the device, the cap nut must be rotated using the handlebar on the one hand, and the head of the tightening bolt must be prevented from rotating using a wrench or the like on the other hand. There was a problem that this operation was troublesome for amateurs.

がきわめて容易になる。 In addition, as mentioned above, in the device of the present invention, the width of the recessed groove formed in the seat post is made to be sufficiently wide compared to the width of the stopper. Even if the fitting part of the vertical pipe and seat post becomes slightly deformed by operating the vertical pipe and the seat post becomes difficult to slide between them, the seat post can still be rotated slightly to the left or right relative to the vertical pipe. , the seat post can be adjusted up and down relatively easily. In addition, in the device of this invention, the anti-rotation piece formed integrally with the stopper suppresses the rotation of the head of the tightening bolt, so the seat post can be tightened by rotating only one nut without using a wrench or the like. This makes handling extremely easy.
