  That is, in many cases, the belt guide 81 (83) is provided at the foremost portion in the longitudinal direction of the frame 43 that holds the drive belt 41 while extending in the operation direction of the slide door 4. Further, usually, the belt guide 81 has a strength capable of protecting the drive belt 41 located inside in the radial direction. Therefore, according to the above configuration, the front end 43f of the frame 43 can be easily positioned in the housing recess 30 with a simple configuration.

  (4) Each pulley support 44 (44f, 44r) provided at the front end 43f and the rear end 43r of the frame 43 is coaxial with the support shaft (pulley pin 47) of the pulley 42 (42f, 42r). In the position shown below, there are protruding portions 71 and 74 protruding downward from the bottom surface 43s of the frame 43. The floor portion 56 of the housing recess 30 is provided with recesses 73 and 76 with which the respective protrusions 71 provided on the frame 43 side engage.

  According to the above configuration, the first and second body-side engaging portions X1, X2, which can easily position the frame 43 in the housing recess 30 with a simple configuration, and the first and second devices. The side engagement portions Y1 and Y2 can be formed. Then, by using the support structure of the pulley 42 by the frame 43, the manufacturing cost can be reduced.

  (5) The frame 43 is fixed to the accommodation recess 30 in a state where it is separated from the side wall portion 80 (80f, 80i, 80r) and the floor portion 56 by being fastened to the ceiling portion 53 of the accommodation recess 30. .

  According to the above configuration, it is possible to suppress the contact sound of the frame 43 caused by the vibration of the vehicle body 2 and reduce the impact transmitted to the sliding door opening / closing device 40. And, by the above-described configurations (1) to (4), appropriate positioning can be performed, so that the fastening operation can be performed quickly.

  The above embodiment can be implemented with the following modifications. The above embodiment and the following modified examples can be implemented in combination with each other within a technically consistent range.

  In the above embodiment, the direction in which the slide door 4 moves toward the front of the vehicle is defined as the first operation direction, and the direction toward the rear of the vehicle is defined as the second operation direction. Further, the front end 43f of the frame 43 is provided with a contact portion 82 that contacts the side wall portion 80f on the vehicle front side (the first operating direction side) of the housing recess 30. The frame 43 pivots about the first device-side engaging portion Y1 provided on the front end 43f, whereby the rear end 43r is inserted into the housing recess 30.

  However, the present invention is not limited to this. The direction in which the slide door 4 moves toward the vehicle rear side is defined as a first operating direction, and the direction toward the vehicle front side is defined as a second operating direction. Further, in this case, a contact portion 82 is provided for the rear end 43r of the frame 43 arranged in the first operation direction of the slide door 4 to contact the side wall portion 80r on the vehicle rear side of the housing recess 30. When the frame 43 rotates around the first device-side engaging portion Y1 provided on the rear end portion 43r as a fulcrum, the front end portion 43f arranged in the second operating direction in the housing recess 30 is moved. It may be configured to be inserted.

  In the above embodiment, the sliding door 4 is closed from the rear side of the vehicle to the front side and is opened from the front side of the vehicle to the rear side. The present invention may be applied to a “front opening” configuration in which the opening operation is performed from the rear side toward the front side.

  In the above-described embodiment, each belt guide 81 (81a, 81b) provided on the pulley support portion 44f on the front end 43f side is in contact with the side wall portion 80f on the vehicle front side of the housing recess 30 on the frame 43 side. It functions as the contact portion 82. However, the present invention is not limited to this, and a configuration may be adopted in which the contact portion 82 with the side wall portion 80f of the housing recess 30 is set at a position other than the pulley support portion 44f on the front end portion 43f of the frame 43. The shape of the contact portion 82 may also be arbitrarily changed.

Further, when the belt guide provided on the pulley support portion 44 functions as the contact portion 82, the configuration of the belt guide may be changed.
For example, as in a frame 43B shown in FIGS. 16 to 18, the belt support 91 is provided on the second support piece 45b of each belt guide 91 (91a, 91b) constituting the pulley support portion 44f on the front end 43f side. The lower belt guide 91b is arranged radially outside the pulley 42 (42f) from the upper belt guide 91a provided on the first support piece 45a. Thus, the lower belt guide 91b may be configured to function as the contact portion 82.

  Even with such a configuration, the same effect as in the above embodiment can be obtained. Note that the upper belt guide provided on the first support piece 45a may be arranged radially outward from the lower belt guide provided on the second support piece 45b. By shifting the radial positions of the belt guides 91a and 91b, the drive belt 41 can be easily wound around the pulley 42 (42f) supported by the pulley support 44f. .

  In the above-described embodiment, the first and second device-side engaging portions Y1 and Y2 are provided at positions coaxial with the support shaft (the pulley pin 47) of the pulley 42. The formation positions of the first and second device-side engaging portions Y1 and Y2 at the front end 43f and the rear end 43r that constitute the first end and the second end may be arbitrarily changed. Further, the first and second vehicle body-side engaging portions X1 and X2 may be formed as projections, and the first and second device-side engaging portions Y1 and Y2 may be formed as concave portions. One of the first and second body-side engaging portions X1 and X2 is a projection, and the other is a concave portion, and one of the corresponding first and second device-side engaging portions Y1 and Y2 is a concave portion. Alternatively, the other may be configured as a projection.

  In the above embodiment, the frame 43 is fastened to the ceiling 53 of the housing recess 30. However, the fixing structure may be arbitrarily changed. Further, the frame 43 may be in contact with at least one of the side wall portion 80 (80f, 80i, 80r) and the floor portion 56 in a state where the frame 43 is fixed to the housing recess 30. The actuator 50 may be arranged in the housing recess 30 together with the frame 43.

Next, technical ideas that can be grasped from the embodiment and the modified examples will be described.
(A) The slide door opening and closing device, wherein the frame is fixed in the accommodation recess while being separated from a side wall portion and the floor portion of the accommodation recess. As a result, the contact noise of the frame caused by the vibration of the vehicle body can be suppressed, and the impact transmitted to the sliding door opening / closing device can be reduced.

  (B) The slide door opening / closing device, wherein the first and second device-side engaging portions are provided at positions coaxial with a support shaft of the pulley. Thus, the manufacturing cost can be reduced by utilizing the pulley support structure by the frame.
