An operating member H2 is provided at a position, and the operating members H1 and H2 are connected to the door lock L via connecting rods 1 and 10, respectively, so that the door lock L can be unlocked from either side of the operating members H1 and H2. In such a door lock release mechanism, it is necessary to have a structure in which each connecting rod is connected to the door lock release lever so that each connecting rod can be relatively displaced so that the operation of one of the two operating members does not interfere with the other operating member. As this connection structure, for example, those shown in FIGS. 2 and 3 are known. That is, each operation member H1, H2 and the release lever L of the door lock L
The ends of the connecting rods 1 and 10 that connect the rods 1 and 1 are flattened to form elongated holes 1A and 10A, and a flanged shaft 11 is fitted into each of the elongated holes 1A and 10A. Release lever L at the tip of
1, and each connecting rod 1, 10 is movable relative to the release lever L1 within the range of each elongated hole 1A, 10A. However, with this method, it is difficult to assemble the shaft 11 because it is necessary to caulk it, and in order to prevent metal contact noise and suppress rattling between the connecting rods 1 and 10 and the shaft 11. The assembly work is complicated because it is necessary to take measures such as fitting the synthetic resin bushing 12 to the shaft 11 and arranging the spring 13. Furthermore, each connecting rod 1, 10 has a flat plate. long hole 1A crushed into shape,
Since 10A had to be formed, there were problems such as poor workability.

As shown in FIGS. 4 to 6, a rod holder for connecting each connecting rod to a door lock release lever has been proposed in order to solve the problems in the above connection structure. That is, each rod 2
Rod holder 2 holding bent ends of 0 and 21
The locking portion 2A is inserted into the elongated hole L provided in the release lever L2.
3, each rod 20,
21 within the range of long holes L3 and L4 and release lever L2.
This allows for relative displacement. However, in this conventional rod holder, since the long holes L3 and L4 must be formed in the release lever L2, there are problems in that the workability of the release lever L2 is poor and the release lever L2 itself becomes large. Ta.

``Purpose of the invention'' The present invention was made by focusing on these conventional problems, and solves the above problems by engaging the rod holder so that each connecting rod can transmit motion in only one direction. It is intended to.
