BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to a lock mechanism which is attached to a lid of a storage body such as a glove box of an automobile and temporarily locks the lid with respect to the storage body in a closed position.

[0002]

2. Description of the Related Art In order to temporarily lock a lid of various storage bodies such as an automobile glove box in a closed position with respect to the storage body, it is attached to the lid and engages with a striker provided in the storage body. A lock mechanism including a lock member and a knob for releasing engagement of the lock member and the striker has been conventionally used.

As this lock mechanism, there is a lock mechanism proposed in Japanese Patent Application No. 6-124724, which has been proposed before the present applicant.

In the lock mechanism according to Japanese Patent Application No. 6-124724, a lock member is provided on the rear side of the main body mounted on the storage body, and the biasing force is always applied to the main body so that the lock member is biased toward the main body.
A knob is provided on the front side of the main body, and a lever cam is provided between the knob and the lock member, and a second protrusion provided on the knob is contacted with the lever cam from the upper side of the lever cam and the lock is performed. The rod portion of the member is brought into contact with the lower side of the lever cam, respectively.

Therefore, according to this device, by pulling the knob, the lock member can be pulled down against the bias through the lever cam. In this way, the lock member is pulled down once and then moved upward. The striker is put back between the lock member and the main body, the lid is locked in the closed position with respect to the storage body, and the striker sandwiched between the lock member and the main body is locked. The member can be pulled out by pulling down the member, and the lid can be pulled out from the container.

However, the lever cam is used for the purpose of maintaining the state in which the striker is sandwiched between the lock member and the main body, in other words, the state in which the lid is locked in the closed position with respect to the storage body. It is what That is, one end of the lever cam is attached to the eccentric shaft of the key cylinder housed in the housing of the main body, and the lever cam is moved in the left-right direction by the rotation of the key cylinder. Here, a void is formed in the lever cam. Therefore, the key cylinder is set so that this void is located below the knob projection.
When the lever cam is rotated to move the lever cam, even if the knob is pulled, the protruding piece moves only in the empty space, and the lever cam cannot be pushed down. As a result, when the lever cam is moved in this way, the lock member cannot be pulled down by pulling the knob, and the lid can be maintained in the closed position with respect to the storage body. It is said that

[0007]

However, in this type of locking mechanism, it is sometimes required to construct the locking mechanism without using such a key cylinder. However, the locking mechanism disclosed in Japanese Patent Application No. 6-124724. In the mechanism, since the pin provided on the rear end of the key cylinder is inserted into the hole provided at one end of the lever cam and engaged, the lever cylinder is attached directly to the key cylinder, so when the key cylinder is not used, , The lever cam could not be assembled inside the main body, and the lever cam had to be removed. For this reason, in the lock mechanism according to Japanese Patent Application No. 6-124724, when the lock mechanism is configured without using the key cylinder, the first protrusion that abuts on the upper side of the rod portion of the lock member is the lever cam. If the knob is configured to be provided separately from the second protrusion that comes into contact with the key cylinder and the lock mechanism is configured using the key cylinder, the first protrusion is inevitably cut off. Was there.

Further, the movement of the lever cam moved in the main body portion in this way is performed by the rotation of the key cylinder housed in the housing portion outside the main body to which one end of the lever cam is connected as described above. However, in order to facilitate the assembly to the main body part, this key cylinder is
It is configured so that it can be mounted in the hole of the accommodating portion with one touch.

That is, the key cylinder is provided with a cylindrical cylinder portion, the cylinder portion and a circular front plate provided at one end side of the cylinder portion, and the other end portion sideways of the cylinder portion. It has a built-in stopper piece that is constantly urged to stick out. The stopper piece is inserted into the hole wall surface of the hole so that the stopper piece is pulled into the cylinder portion from the front side of the body portion against the bias. After inserting the cylinder part while touching the tip, the other end of the cylinder part is projected from the hole edge of the hole on the back side of the main body part to push the stopper piece to the side part of the cylinder part again by the biasing. To the back edge of the stopper piece that is projected again in this way,
By making the front plate contact the front edge of the front plate, the key cylinder can be rotatably inserted and inserted into the hole of the accommodating portion with one touch.

However, when the key cylinder is inserted into the hole of the accommodating portion by one-touch as described above and attached, the stopper piece is smoothly removed at the edge of the hole of the accommodating portion on the back side. The key cylinder is dimensioned from the front plate to the stopper piece so that the key cylinder is inserted into the hole of the accommodation portion into which the key cylinder is inserted from the hole edge on the front surface side to the hole edge on the rear surface side. It is necessary to set it slightly larger than the dimensions up to.

For this reason, a gap is created between the stopper piece of the key cylinder which is inserted and fitted in the hole of the accommodating portion as described above and the hole edge surface of the hole on the back side. As a result, when this lock mechanism is used in a glove box of an automobile, there is a problem in that the key cylinder rattles in the hole of the accommodating portion and generates abnormal noise due to vibrations generated while the automobile is running. There was something to do.

For this reason, in the conventional locking mechanism of this type, the rear end portion of the key cylinder housed in the hole of the housing portion and the lever cam connected to the key cylinder at the end portion. It is unavoidable to take measures to prevent the rattling, such as interposing a cushioning material between the key cylinders, and the key cylinder that does not have the structure to be attached to the hole of the accommodating portion with one touch as described above. Also in the case of, from the viewpoint of preventing the rattling due to the dimensional error between the key cylinder and the hole of the accommodating portion,
It was unavoidable to take measures such as interposition of the cushion material.

Therefore, according to the present invention, firstly, regardless of whether or not the cylinder key is used, a lock mechanism having a desired function can be easily obtained without adding special features to each component constituting the lock mechanism. An object of the present invention is to provide a lock mechanism having a structure capable of performing the above. Secondly, the key cylinder that constitutes this type of lock mechanism can be inserted with one touch into the mounting hole and without backlash, and the lock mechanism with a structure that can be mounted can be installed without increasing the number of parts. , The purpose is to provide with a simpler structure.
