The assembly of the case and the combination of the upper body and the heart of the case body with the time built with the coil spring, can be made in a separate process from each other. Therefore, their assembling work is facilitated and productivity is improved.

In the present invention, the key mechanism for displacing the stopper piece to the corrected position by the use of a key in the correcting mechanism covered with the cover case is simple in structure and can make production easier. It is known that this type of bicycle has conventionally been provided with a push button type for displacing the stopper piece to a revised position by a predetermined button operation and a revision plate operation by providing a plurality of push buttons that are projected by the cover case and the cover case. It is a lock that attracts the user's attention because it has novelty that is not present in the dragon ring lock. The key type locking mechanism includes a base plate which is fixed to the cover case, front and rear fittings on the cover case, is integrally fixed, and forms an accommodation space of the locking mechanism between the cover case, and both sides are guided to the base plate. One end of the contact part appears in the gap between the stop piece superimposed back and forth and the key plate formed between the side plate of the base plate and the side edge of the stop piece. The other end of the stopper is engaged at the engagement position with the locking portion of the time frame, the middle is coupled to one end of the stop piece, and the stopper piece is stopped and the base plate has a support shaft, and the end piece is hung on the stop piece. A stopper spring which rests on the other end to the stopper piece so that the stopper piece always appears in a contact position with a locking part of the visibility, and the cover case A key which is fitted into a key hole formed in the surface, and engages the front end with the junction part of the stopper piece in the insertion gap of the key, and engages the turn hole penetrating back and forth in the turn part formed by the unevenness on the side edge of the stopper piece. Since it is made of a combination of the back and the like, it is possible to use a reversible key having a turn on both side edges in particular, making it difficult to revise, and has the advantage of easy operation of the revision of the bicycle.

In addition, in the present invention, the push button type locking mechanism is fixed integrally by attaching a cover case in which holes of the button and the same number of holes are drilled on the upper surface, and fitting portions of irregularities formed on the front and rear end surfaces of the cover case. The base plate forming the accommodation space of the correction mechanism between the cover case and the guide hole formed before and after the base plate are fitted with the standing pieces before and after, and the sliding motion is applied in the front and rear directions to overlap the back surface of the base plate. The front and rear edges corresponding to the width of the elastic hanging piece of the button are installed in the front and rear directions, and the reset plate on which the reset button is recessed on the front side of the cover case, and the spring support formed on the base plate, respectively. The return springs are supported and the upper ends of the cover cases are recessed, and the reversing parts formed of recesses and convex parts are provided on the same side of each side, respectively. The cover case is provided with sliding buttons back and forth by providing a plurality of buttons integrally having an elastic ruled piece formed in a hooked shape at the lower end so as to engage the part and the recess, and an uneven part engaged with the turn part on the side of the button. The engaging part which rotates a stopper piece in the revision direction in the front part side part of the revision part has the revision plate which has an opening button which protrudes to the rear side of the cover case at the other end, and the operation part which contact | connects the junction part of a revision plate at one end, and the said correction part at the other end A stopper piece which is formed with a rocking material on a knock pin that fixes the cover case together with a correcting mechanism suspended on the back of the cover case and hangs at the engagement position with the engaging portion of the liver; Tangier springs are mounted on the knock pins and are secured so that the stopper piece is always released to the engagement position with the locking portion of the visibility. The pushbutton type locking mechanism for fixing the reset plate together with the cover case to the integrally formed mounting part is flattened by combining the reset plate with a pressing spring for holding the pushbutton against the elastic locking piece of the pushbutton. Its use is very easy.

In addition, a large number of pushbuttons may make it difficult to arbitrarily revise. Further, in the present invention, the reset plate is provided with a protruding piece approaching the time interval, and on the side surface of the time interval, the locking portion slid along with it is supported by the elastic spring and passes through the stopper portion of the stopper piece. In the reciprocating stroke pulled by the coil spring and returning to the correct position, a contacting contact portion is formed in contact with the protruding piece to interlock the reset operation on the reset plate, and the stopper piece has a length corresponding to the reciprocating stroke and is fixed. The holding part holding the stopper part of the stopper piece in the correct position in contact with the side of the inner side is provided by the operation when the projecting piece that has passed through the engagement authority of the stopper piece returns to the stop position when the locking part is rotated to the corrected position. The engagement contact unit is moved in the reset direction, and the lock is released to automatically return by releasing the latch of each push button by the reset plate. The set is made.
