If it is controlled to stop and is rotated from the retracted position to the standby position, the stop control is performed to the standby position.

  When the drive rotary plate (13) is stopped at the standby position, the striker (14) is restrained to the standby position, and when the drive rotary plate (13) is stopped at the retracted position, the striker (14) Is constrained to the retracted position. Further, when the drive rotating plate (13) rotates from the retracted position toward the standby position, the engaging pin (13a) comes into contact with the contact arm portion (17b) of the open lever (17), so that the open lever ( The striker (14) is moved from the retracted position to the standby position while rotating 17) in the release direction.

Next, the operation of one embodiment of the present invention will be described.
When the trunk lid is open, as shown in FIGS. 1 and 2, the drive rotating plate (13) in the closure device (8) stops at the standby position, and the striker (14) is restrained at the standby position. ing. When the striker (14) is in the standby position, the striker (14) is engaged so that the latch (4) of the latch means (1) can be easily engaged with the engagement portion (14a) of the striker (14). The portion (14a) slightly protrudes from the peripheral edge of the trunk opening.

  When the trunk lid is manually closed, the contact portion (2a) of the base member (2) in the latch means (1) first contacts the lift portion (15a) of the lift lever (15) from above, and the lift spring The latch (4) in the open position is engaged with the striker (14) that is restrained in the standby position while rotating the lift lever (15) toward the lowered position against the urging force of (16). Engage with the joint (14a) from above. As a result, as shown in FIG. 3, the latch (4) rotates to the latch position, and the claw portion (6a) of the locking plate (6) engages with the outer peripheral edge of the latch (4). The lid is once held in a slightly open half-latch position.

  When the trunk lid is closed to the half latch position, the reaction force of the sealing material provided at the periphery of the trunk opening does not act so much, so that the engagement portion (14a) between the latch (4) and the striker (14) Can be engaged with a light force. Therefore, when the trunk lid is closed, the generation of a loud door closing sound can be suppressed.

When the latch (4) of the latch means (1) is engaged with the engaging portion (14a) of the striker (14), this state is detected by a half latch detection switch (not shown), so that the motor (10) The forward rotation is controlled by the control device, and the drive rotary plate (13) is rotated from the standby position to the retracted position via the output shaft (12). With the rotation of the driving rotary plate (13), the striker (14), by the displacement of the engaging pin engaged with the cam groove (19) (13a), is moved toward the standby position to the retracted position The trunk lid is forcibly moved from the half latch position toward the full latch position against the reaction force of the sealing material via the latch means (1). At this time, the lift lever (15) also moves in the same direction as the striker (14) with the lowered position. As shown in FIG. 4, when the striker (14) reaches the retracted position, the position is detected by a full latch detection switch (not shown), and the motor (10) is controlled to stop. As a result, the drive rotating plate (13) and the striker (14) are stopped at the retracted positions.

  In one embodiment of the present invention, the lift lever (15) is provided on the striker (14), and the lift spring (16) is provided between the lift lever (15) and the striker (14) to provide the striker (14). With the movement from the standby position to the retracted position, the lift lever (15) and lift spring (16) are also displaced in the same direction together with the striker (14), and the striker (14) and lift lever (15) Thus, the striker (14) can be moved from the standby position to the retracted position without resisting the urging force (lift force) of the lift spring (16). Therefore, the trunk lid can be moved from the half latch position to the full latch position with a small force without resisting the biasing force of the lift spring (16).

Further, since the positional relationship between the striker (14) and the lift lever (15) does not substantially change, move when the lift lever (15) is in the lowered position, the standby position of the striker (14) to the retracted position Accordingly, even if the trunk lid moves from the half latch position to the full latch position, the urging force of the lift spring (16) acting on the lift lever (15) is held substantially constant. Therefore, as compared with the case where the trunk lid is at the half latch position, the lift force at the full latch position does not become excessive, so that the operation force at the full latch position of the trunk lid is not deteriorated.

  When the trunk lid is in the full latch position, that is, when the trunk lid is closed, the motor (10) is controlled to rotate forward when an open operation switch (not shown) provided in the driver's seat of the vehicle is operated. Thereby, from the state shown in FIG. 4, the drive rotary plate (13) is rotated in the drive direction via the output shaft (12) of the drive means (11). The engaging pin (13a) abuts on the abutting arm portion (17b) of the open lever (17) and rotates the open lever (17) in the release direction as the drive rotating plate (13) rotates. Move the striker (14) from the retracted position to the standby position. At this time, when the open lever (17) is moved in the release direction, the release arm portion (17a) of the open lever (17) contacts the release portion (6b) of the locking plate (6) in the latch means (1). Then, the locking plate (6) is rotated in the release direction, and the engagement between the latch (4) and the striker (14) is released. By this. The trunk lid is lifted by a predetermined amount by the urging force of the lift spring (16) and can be opened.
