An eighth aspect of the present invention is characterized in that the decorative garnish is provided outside the vehicle body and the resin garnish is provided inside the vehicle body.

In the invention according to claim 1, the hollow support member is formed in a substantially rectangular cross section, and the long side of the substantially rectangular cross section intersects the blind spot boundary line of the front pillar structure. And the front part (front short side) of the hollow support | pillar member was provided in the vehicle width direction outer side from the rear part (rear short side).
Therefore, the short side of the substantially rectangular cross section can be arranged along the vehicle width direction.
Thereby, it becomes possible to suppress the dimension (namely, width dimension) of a hollow support | pillar member in the vehicle width direction small, and can suppress the blind spot range of a front pillar structure small.

Furthermore, by crossing the long side of the substantially rectangular cross section with the blind spot boundary line of the front pillar structure, the load transmitted from the front of the vehicle body or from the side of the vehicle body is partially loaded along the long side (that is, the long side is seated). Acting as a bending load).
Therefore, the long side can support a load larger than a load orthogonal to the long side (that is, a load that bends and deforms the long side).

As a result, the hollow column member can ensure sufficient strength (rigidity) against a load from the front of the vehicle body and sufficient strength (rigidity) against a load from the side of the vehicle body.
By providing the hollow pillar member on the front pillar, the strength (rigidity) of the front pillar can be increased.
By the way, the front part of the hollow column member is provided on the outer side in the vehicle width direction from the rear part.
Therefore, the front part of the hollow column member can be separated relatively far from the blind spot boundary line on the vehicle compartment side.
Thereby, the waterproof seal part of the resin garnish can be greatly extended from the front part of the hollow support member to the blind spot boundary line on the vehicle compartment side, and a sufficient amount of extension of the waterproof seal part can be ensured.
By sufficiently securing the protruding amount of the waterproof seal portion, a large groove depth dimension of the drip groove provided between the waterproof seal portion and the windshield can be ensured.

By storing the front portion of the hollow support member in the restriction portion having a substantially U-shaped cross section, the width dimension of the restriction portion in the vehicle width direction can be made larger than that of the front portion of the hollow support member.
Thereby, the intensity | strength (rigidity) of the control part of a substantially U-shaped cross section can be improved with respect to the bending of a vehicle width direction.

  In addition, by increasing the strength (rigidity) of the restricting part against bending in the vehicle width direction, it becomes possible to reduce the size of the short side (that is, the vehicle width direction) of the hollow support member, and the front pillar structure The blind spot range can be further reduced.

In the invention which concerns on Claim 3, the decoration garnish of the same color as a vehicle exterior was provided in the front part of the outer panel, and this decoration garnish was made to protrude on the both sides of the front part along the front part of an outer panel.
As a result, it is possible to secure a large width dimension in the vehicle width direction of the decorative garnish to make the appearance of the front pillar thick, and to give a sense of security to the appearance (strength) of the front pillar.

Here, since the vehicle of the sashless door does not include the window frame on the door, the strength (rigidity) of the vehicle body is often imposed on the front pillar.
Thus, particularly in the case of a sashless door vehicle, it is important to give the appearance of the front pillar thick and give a sense of security to the strength (rigidity) of the front pillar.

In the invention which concerns on Claim 4, the surface of the decoration garnish was arrange | positioned substantially flush with respect to the surface of a waterproof seal part by providing a decoration garnish on the surface of a wind-mold main body.
