クが錠止点に集中負荷されることになり、錠止点の歪曲
変形や剪断破壊を起こしやすい。As described above, in the conventional device, the locking of the locking shaft with respect to the seat body depends only on the engagement between the handle engaging / disengaging groove of the connecting flange and the projecting portion of the locking member. Since the stopping point is located near the center of rotation of the locking shaft, when the key handle is turned strongly, a large rotational torque is concentrated on the locking point, resulting in distortion of the locking point and shear failure. Easy to cause.

が多いと製品コストが嵩むことになる。As described above, the locking point due to the engagement between the protrusion of the locking member and the handle engaging / disengaging groove is located at a position close to the center of rotation.
Since there is a large difference between the distance from the rotation center to the handle engagement groove and the distance from the rotation center to the insertion hole, the gap error between the protrusion and the handle engagement groove is caused by the notch of the insertion hole and the notch of the mounting flange. The degree to which the phase error appears between the concave portions is increased. Therefore, when the actuating projection of the key handle is pulled out of the handle engaging / disengaging groove through the insertion port, the protrusion of the locking member may not correctly face the handle engaging / disengaging groove. There was a risk that the lock would be left unsatisfied. In order to prevent such a danger, it is necessary to sufficiently reduce the tolerance of the gap between the protrusion of the locking member and the handle engagement / disengagement groove. If the loss is large, the product cost increases.

However, in the conventional apparatus, the thickness of the main body of the locking member manufactured by press-molding a metal plate is thin, and the contact portion of the outer peripheral surface of the main body with the inner wall surface of the recess is formed. The effective dimensions were relatively small. Therefore, when a large rotation torque is applied to the contact portion, the main body of the locking member may be distorted or buckled, and the locking function between the receiving main body and the locking shaft may be lost. there were.

An insertion hole 38 for the lock shaft 3 is provided at an intermediate portion of the lock shaft 3, and the locking member 10 is slidable in the length direction of the lock shaft 3. The front end face of the mounting flange 4 and the rear end face of the connecting flange 5 are in contact with each other, and the plate thickness of the operating projection 8 substantially matches the depth of the handle engagement groove 6. On the front end face of the mounting flange 4, an escape groove 17 in which the retaining protrusion 20 of the key handle 7 moves freely is provided in an arc shape.

Since the inner surface of the peripheral wall 43 of the connecting flange 5 and the inner surface of the shaft hole 28 are in contact with each other, an appropriate frictional force is obtained. The initial rotation position is maintained, and the lock position is not returned unnecessarily.

The engagement between the locking groove 46 of the connecting flange 5 and the locking sleeve 29 of the locking member 10, and the engagement between the handle engaging / disengaging groove 6 of the connecting flange 5 and the projection 12 of the locking member 10. In this case, the rotation torque applied to the locking point is dispersed, and the method depends on only one type of engagement between the handle engaging / disengaging groove of the connecting flange and the protrusion of the locking member. Higher locking performance can be obtained as compared with the conventional device.

機構の全体強度が増大する。The locking sleeve 29 of the locking member 10 is fitted into a receiving groove 46 provided on the inner wall surface of the concave portion 9 of the mounting flange 4, and the locking sleeve 29 projects out of the projection 12. Since the locking groove 46 of the connecting flange 5 is provided on the inner wall surface of the handle engaging / disengaging groove 6, the locking point by the engagement between the locking sleeve 29 and the locking groove 46 is set from the rotation center of the locking shaft 3. It is set at the maximum distance. Therefore, it depends only on the engagement between the handle engagement groove of the connecting flange and the protrusion of the locking member, and the locking point is distorted and deformed compared to the conventional device in which the locking point is relatively close to the center of rotation. No shearing or shearing occurs, greater resistance to rotational torque can be achieved, and the overall strength of the locking mechanism is increased.

すことができるため、製品コストの低減が可能である。As described above, the locking point due to the engagement between the locking sleeve 29 and the locking groove 46 is located at a position farthest from the center of rotation, and the distance from the center of rotation to the locking groove 46 and the distance from the center of rotation. Since the difference from the distance to the insertion slot 33 is set sufficiently small, even if there is a manufacturing error in the gap between the locking sleeve and the locking groove, the gap error is caused by the notch recess of the insertion slot and the mounting flange. The extent to which the phase error between the notched concave portions is enlarged and appears is negligibly small. Therefore, the insertion port 33
When the actuating projection 8 of the key handle 7 is pulled out from the handle engaging / disengaging groove 6 through the lock sleeve 29, the locking sleeve 29 correctly faces the locking groove 46, and the locking between the receiving body 2 and the locking shaft 3 is not performed. It always holds true. Therefore, the locking sleeve 29 and the locking groove 4
6, the width of the allowable error of the gap 6 can be made relatively large, and the occurrence rate of defective products due to dimensional errors can be reduced by that much, so that the product cost can be reduced.

性がない。The locking member 29 is fitted into the receiving groove 45 of the mounting flange 4 so that the locking member 10 is non-rotatably held with respect to the mounting flange 4.
The locking sleeve portion 29 has a sufficiently large height,
Since the effective dimension of the contact portion of the receiving groove 45 with each inner wall surface is large, even if the locking member 10 is manufactured by press-molding a metal plate, the locking sleeve can be subjected to a large rotational torque load. The portion 29 is not deformed or buckled, and there is no danger that the locking function between the seat main body 2 and the locking shaft 3 is lost.
