Referring to fig. 4, 5, and 7 to 10, the seat striker member 70 is attached to the lower surface 52a of the coupling portion 52 of the handle member 50. Specifically, the seat lock member 70 is attached to the lower surface 52a of the one side portion 53a of the coupling portion 52 and positioned below the coupling portion 52.

As shown in fig. 5, the seat latch member 70 engages with the engaging portion 45 in the insertion opening 58 of the insertion coupling portion 52 of the seat 14 from above, thereby locking the seat 14 in the closed state.

The seat lock member 70 includes a housing 71, a lock piece 72 movable in the housing 71, and an operation cable 73 (fig. 4 and 5).

The housing 71 includes a housing main body portion 74 attached to the one side portion 53a and a lock portion 75 located below the insertion opening 58.

The lock portion 75 includes a lock hole 75a into which the engagement portion 45 of the seat 14 is inserted from above, and an abutting portion 75b against which the lock piece 72 abuts.

The lock hole 75a is a vertically long hole that penetrates the lock portion 75 in the front-rear direction, and is open upward as viewed from the front.

The lock piece 72 closes the open portion of the upper portion of the lock hole 75a in a state of abutting against the abutting portion 75 b.

The engaging portion 45 of the seat 14 is locked to the seat lock member 70 by restricting the position of the front-rear extending portion 45a between the lock piece 72 and the lock hole 75 a.

The lock piece 72 is provided slidably in the vehicle width direction in the housing 71, and the lock piece 72 abuts against the abutting portion 75b by an urging member (not shown) incorporated in the housing 71.

The lock piece 72 operates in conjunction with the operation of the operation cable 73, and the lock piece 72 operates by operating the operation cable 73 with a key held by a passenger, for example. When the operation cable 73 is operated, the lock piece 72 slides in the vehicle width direction in a direction away from the abutting portion 75b against the urging force of the urging member. Thereby, the locked state by the locking piece 72 is released, and the engaging portion 45 of the seat 14 can be disengaged upward.

The lock piece 72 includes a cam surface 72a inclined downward toward the abutting portion 75b on the upper surface. When the engaging portion 45 of the seat 14 is inserted into the insertion opening 58 from above, the lower surface of the front-rear extending portion 45a pushes the cam surface 72a open, and the lock piece 72 slides in a direction away from the abutting portion 75 b. When the front-rear extension portion 45a is inserted below the lock piece 72, the lock piece 72 is brought into a state of abutting against the abutting portion 75b by the urging force of the urging member. Thereby, the seat 14 becomes the locked state.

When the engaging portion 45 of the seat 14 is inserted into the insertion opening 58 from above, it is guided by the peripheral edge portion of the insertion opening 58. Specifically, the narrow portion 58a of the insertion opening 58 is formed to be slightly wider than the vehicle width direction thickness of the engagement portion 45 so as to be able to guide the engagement portion 45. When the seat 14 that is closed by pivoting about the hinge portion 25a is slightly displaced in the vehicle width direction, the engaging portion 45 is guided in contact with the narrowed portion 58 a.

In the present embodiment, since the insertion opening 58 is provided in the connection portion 52 of the handle member 50, the structure of the seat latch member 70 can be simplified.

As shown in fig. 8, the substrate 53 includes positioning holes 53c vertically penetrating the substrate 53.

The seat lock member 70 includes a shaft-shaped positioning portion 76 inserted into the positioning hole 53c from below.

Further, a seat lock fixing bolt 77 inserted from above into the base plate 53 is fastened to the housing 71 of the seat lock member 70.

That is, the seat latch member 70 is positioned on the base plate 53 by the positioning portion 76, and is fixed to the base plate 53 by the seat latch fixing bolt 77.

Referring to fig. 3 to 5, in a state where the seat 14 is closed, the handle member 50 is covered from above by the rear portion of the seat 14 locked by the seat latch member 70, and the seat latch member 70 is attached to the lower surface 52a of the coupling portion 52 of the handle member 50 and covered from above by the coupling portion 52.

Therefore, referring to fig. 3, even when attempting to pry the lower edge 14c of the seat 14 and the side covers 34, 34 apart by a bar or the like to access the seat latch member 70, the coupling portion 52 becomes an obstacle and the seat latch member 70 becomes difficult to access. Therefore, it is difficult to open the seat 14 from the outside and enter the storage box 25, and the like, and therefore theft prevention can be improved.

Referring to fig. 1, 3, and 5, the

handle portions

51, 51 are positioned on the outer side of the seat lock member 70, and the

handle portions

51, 51 overlap the lower edge 14c of the seat 14 and the upper edge 34a of the side cover 34 in a side view, covering the lower edge 14c and the upper edge 34a from the outer side. Therefore, even when the seat latch member 70 is approached from between the lower edge 14c of the seat 14 and the side covers 34 and 34, the

handle portions

51 and 51 become obstacles, and thus the theft prevention performance can be improved.

The seat lock member 70 is covered from the front and the side by the wall portion 60 of the coupling portion 52, and is covered from the rear by the left attachment leg portion 56 and the bracket 42. This makes it difficult to access the seat lock member 70 from the outside, and thus the theft prevention performance can be improved.
