According to the first aspect of the present invention, the lock piece is attached to the opening / closing body in a posture along the surface that closes the opening of the recess. Therefore, when the housing unit is assembled to the vehicle body, the lock piece and the surrounding structure are in contact with each other. This makes it difficult to prevent the lock device from being damaged or malfunctioning. In addition, since the lock piece is provided along the opening / closing body in such an attitude, it is possible to suppress the size of the locking device from being increased as compared with the case where the lock piece and the operating mechanism thereof are provided in the recess or the outer periphery of the opening / closing body. it can. Then, the tip of the lock piece can be locked to a lock piece locking portion provided on the peripheral wall of the recess at a position away from the arm portion by the operation of the drive mechanism, and the opening / closing body is fixed by locking the lock piece. With this configuration, the lock strength of the opening / closing body can be increased as compared with the case where the opening / closing body is fixed by the lock piece at a position near the hinge.

  According to the second aspect of the present invention, the opening / closing body is configured to have the internal space, and at least a part of the lock piece is housed in the internal space. Therefore, when the housing unit is assembled to the vehicle body or the like, It becomes more difficult to make contact with the structure, and damage and malfunction of the lock device can be prevented.

  According to the third aspect of the invention, since the lid is configured by the combination of the inner member and the outer member, the lid has an internal space as compared with the case where the lid is configured by a single resin molded product. Easy to do. Therefore, it is possible to realize the second invention with a simple configuration and easily obtain the effect.

  According to the fourth aspect of the invention, the entire lock piece or substantially the whole of the lock piece except the portion that needs to be projected to the outside for the lock function is housed in the internal space of the opening / closing body. It is possible to avoid contact between the lock piece and the surrounding structure when the lock piece is assembled to the vehicle body or the like. Further, even when the opening / closing body is opened, the lock piece is not exposed at all or almost outside, so that the design of the housing unit can be improved.

  According to the fifth invention, since the arm accommodating portion projects laterally from the recess, there is a space at a position adjacent to the arm accommodating portion and the recess on one side of the pivot of the hinge arranged in the arm accommodating portion. Although it is formed, since the drive mechanism is arranged in the space, the housing, the opening / closing body, and the locking device can be compactly assembled to reduce the size of the housing unit.

According to the sixth aspect of the invention, the lock piece is configured to combine the first lock piece and the second lock piece that advance and retreat in conjunction with each other but have different advance and retreat directions. The degree of freedom of the position can be increased, and the lock position can be made flexible according to the peripheral layout of the assembly target part such as the vehicle body.

According to the seventh aspect , when the operating piece moves in the traveling direction and is inserted into the hooking hole when the opening / closing body is in the closed position, the operating piece engages with the operating piece hooking portion to open the opening / closing body. Is fixed to the housing. Further, when the operating piece inserted into the hook hole comes into contact with the lock piece and further moves in the advancing direction in the contact state, the lock piece moves in the advancing direction in conjunction with the operating piece, and the tip of the lock piece Is hooked on the hook. This also fixes the opening / closing body to the housing. Since the double lock that locks the opening / closing body to the housing at two positions is adopted as described above, the locking strength of the opening / closing body can be further enhanced.

  Here, when the switching operation of the locked state is automatically performed with the opening / closing body being opened, and the operating piece is unintentionally moved in the traveling direction to be in the locked state, the operating piece is inserted into the insertion hole. It moves in the direction of movement at a position away from it and sticks out to the back side of the arm. Then, even if the opening / closing body is to be closed, the arm part engages with the lock piece, so that the opening / closing body cannot be closed. Further, since it cannot be visually determined that the lock piece is in a protruding state, there is a possibility that the arm portion or the lock piece may be damaged when trying to close the opening / closing body without knowing it.

On the other hand, according to the seventh aspect , since the movement of the operating piece is unintentionally moved in the traveling direction when the opening / closing body is in the open state, the movement of the operating piece is restricted by the lock restricting portion. It is possible to prevent the operating piece from protruding to the back side of the arm portion. As a result, it is possible to avoid a situation in which the arm portion falls into the actuating piece and the opening / closing body cannot be closed, and the arm portion and the lock piece are not damaged by the closing operation of the opening / closing body.

According to the eighth aspect of the invention, the lock piece is configured to combine the first lock piece and the second lock piece that advance and retreat in conjunction with each other but have different advance and retreat directions. The degree of freedom of the position can be increased, and the lock position can be made flexible according to the peripheral layout of the assembly target part such as the vehicle body.

According to the ninth aspect , it is possible to reliably perform the locking operation of locking the lock piece on the lock piece hooking portion. This will be described below.

  If the operating piece and the lock piece are in the intersecting direction, the bending force is applied to the operating piece and the lock piece when the locking piece is pushed by the movement of the operating piece in the moving direction. Bending may occur. Further, there is a possibility that the amount of advance / retreat of the lock piece may change relatively greatly due to the variation in the assembling accuracy of each component that constitutes the lock device. Therefore, even if the operating piece moves in the moving direction, the locking piece does not move in the moving direction for a predetermined distance in association with the moving piece, which may cause a defective locking operation.

On the other hand, according to the ninth aspect of the invention, the operating piece and the locking piece move forward and backward in the same direction in conjunction with each other in a connected state, so that the locking piece is pushed by the movement of the operating piece in the traveling direction. At that time, it is possible to suppress the actuating piece and the lock piece from being bent, and to transmit the pressing force in the traveling direction from the actuating piece to the lock piece with a small loss. Further, it is possible to reduce a change in the amount of advance / retreat that occurs in the lock piece due to a variation in the mounting accuracy of each component constituting the lock device with respect to the housing or the opening / closing body. As a result, the lock piece can be moved over a distance corresponding to the amount of movement of the actuating piece in the traveling direction, and a reliable locking operation can be realized by locking the lock piece.

According to the tenth invention, since the lock piece and the operating piece are linearly connected to each other, the bending of the operating piece and the lock piece during the lock operation are effectively suppressed, and each of the lock devices is configured. It is possible to suitably reduce the change in the amount of advance / retreat of the lock piece due to the variation in the assembly accuracy of the parts. As a result, the locking operation by hooking the lock piece can be performed more reliably.

According to the eleventh aspect , the lock piece and the operating piece are connected by a fitting structure that fits in the rotation direction of the opening / closing body, and are connected or released in accordance with the opening / closing operation of the opening / closing body. Therefore, it is possible to connect the lock piece and the operating piece by only closing the opening / closing body to make the lock operation possible, and to open the opening / closing body only. Since and are separated, the opening operation of the opening / closing body is not hindered. Therefore, a separate complex mechanism is not required for the structure in which the lock piece and the operating piece can be connected and released, and the opening / closing operation of the opening / closing body is not complicated.

According to the twelfth aspect of the invention, since the push-back portion that pushes back the operating piece that has moved in the traveling direction by the closing operation of the opening / closing body is provided, the operating piece advances unintentionally when the opening / closing body is in the open state. Even when moving in the direction, the operating piece can be pushed back by closing the opening / closing body. As a result, it is possible to avoid the situation in which the opening / closing body cannot be closed due to the fact that the opening / closing body does not close, and the closing operation of the opening / closing body does not damage the opening / closing body itself or the lock piece.

According to the thirteenth aspect , when the opening / closing body is in the open position, the operating piece moved in the traveling direction is pushed back to the position connectable to the lock piece by the closing operation of the opening / closing body, so that the opening / closing body is closed. The actuating piece can be connected to the lock piece by itself. Accordingly, it is not necessary to separately provide a complicated mechanism for connecting the operating piece and the lock piece that are unintentionally moved in the traveling direction when the opening / closing body is in the open state.

According to the fourteenth invention, since the lock piece is biased in the backward direction by the biasing member, if the holding of the lock piece at the position where the lock is advanced is stopped, the lock piece moves in the backward direction, The tip of the lock piece is removed from the hooking portion, and the locked state is released. Therefore, the drive mechanism only needs to have a function of moving the lock piece in the traveling direction, and can be realized with a simple configuration.

  Here, if only the above-mentioned biasing member is provided, the lock piece may move too much in the backward direction due to the biasing force of the biasing member and may be displaced from the predetermined retracted position. If the lock piece deviates from the predetermined retracted position, the drive mechanism and the lock piece will not be connected to each other, and the forward / backward movement of the lock piece may become uncontrollable.

On the other hand, according to the fourteenth invention, since the movable range of the lock piece in the backward direction is limited by the stopper, it is possible to prevent the lock piece from moving too much in the backward direction by the urging force of the urging member. Therefore, the forward / backward movement of the lock piece can be maintained in a well controllable state.

According to the fifteenth invention, since it has the same configuration as the lock device of the first invention, the same operational effect as that of the first invention is obtained, and damage and malfunction of the lock device are prevented, and the lock device is large-sized. The lock strength of the opening / closing body can be enhanced.
