ようにする点にある。In the conventional key device, a pressing body 54 bent in a box shape is formed in the latch body 53 with pressing portions a formed at both ends of the latch body 53 in the withdrawal direction. The recessed portion 53 is of a size that allows the latch body 53 to move in and out between the engaged position and the disengaged position of the latch body 53 when the pressing body 54 is in the retracted state.
Since A has to be formed, the dimension of the latch main body 53 in the retracting direction becomes large. Further, the latch body 5
Two projections 5 provided with the cam surface b in the recess 53A of No. 3
It is necessary to secure a space for projecting and forming 6 and the latch main body 53 has the coil spring 5
At the disengagement position against the elastic restoring force of No. 7, a gap is formed between the tops of the cam surfaces b and the inner surface of the top plate portion of the pressing body 54 that opposes the cam surfaces b in the axial direction of the bolt. In terms of the appearance, the depth of the recess 53A formed in the latch body 53 is the sum of the dimension of the pressing body 54 in the bolt axis direction and the dimension of the gap in the bolt axis direction. Therefore, the width of the latch main body 53 in the bolt axis center direction and the width of the latch main body 53 in the extending / retracting direction and the direction substantially orthogonal to the bolt axis center direction both become large. As a result, there is a problem that the entire key device becomes large in the three-dimensional direction. Further, in this conventional device, the pressing body 54
After fixing the casing C in which the latch main body 53 is installed to one side surface of the door A, the top plate portion of the case 51, the lid 52, and the long holes 51a, 52a formed in the latch main body 53 and the pressing body 54, respectively. Since the bolt 50 is inserted into the doors 53a and 54a from one side surface side of the door A, the sliding guide during the pulling operation of the inserted bolt 50 is performed only by the through hole formed in the door A. Therefore, if the processing accuracy of the through hole is low, rattling may occur in the operating shaft 50 and the operating member 58 connected to the other end thereof. Moreover,
Since a large long hole 51a is formed in the top plate portion of the case 51, dust may easily enter from the long hole 51a and accumulate, resulting in malfunction of the latch body 53. There is room for improvement in the external appearance of the key device. The present invention has been made in view of the above-mentioned circumstances, and an object thereof is to make a comparison with the prior art by rationally devising a cam surface formed on the latch body and a pressing body provided on the operation shaft. Then, the entire key device can be compactly constructed in the direction in which the latch body is extended and retracted, the axial direction of the operation shaft, and the direction substantially orthogonal to both directions.

できる。According to the first characteristic construction of the key device of the present invention, one of the means for operating the latch main body to the unlocked position against the elastic restoring force of the elastic biasing body in accordance with the operation of the operation shaft is provided. The pressing body is formed at one end of the operating shaft in a direction substantially orthogonal to the direction in which the latch main body extends and retracts and the axial direction of the operating shaft.
It is but because, in forming a through hole in the latch body also, a space to allow the output retraction movement across the engaged position and the disengaged position of the latch body, the width in the projecting and retracting direction of the latch body is small Since it is only necessary to consider the space into which the pressing body enters, the size of the latch main body in the retracting direction can be reduced.
