1. A straddle vehicle comprising:
a steering stem coupled to a handle; a front fork extending in parallel with the steering stem and supporting a front wheel at a lower end portion thereof such that the front wheel is rotatable; a head pipe into which the steering stem is inserted; a ring-shaped seal member provided at an end portion of the head pipe to seal a gap between the head pipe and the steering stem; a bearing retaining section provided on an inner peripheral side of the end portion of the head pipe; a bearing retained in the bearing retaining section to support the steering stem such that the steering stem is rotatable; and a circular tubular portion pressed against an end surface of the bearing, the circular tubular portion having a circular outer shape when viewed from an axial direction; wherein the ring-shaped seal member has a lip portion provided on an inner peripheral portion thereof and an engagement portion provided on an outer peripheral portion thereof; wherein the engagement portion is engaged with an inner peripheral surface of the head pipe; wherein the lip portion extends radially inward from the engagement portion to be close to the circular tubular portion and is biased to slidably contact an outer peripheral surface of the circular tubular portion; wherein the circular tubular portion is separate from an inner ring of the bearing; wherein a portion of the circular tubular portion, the portion on which the lip portion slidably contacts, has a smaller outer diameter than the inner ring of the bearing, the portion of the circular tubular portion being located radially inward relative to the inner peripheral surface of the head pipe; and wherein the bearing retaining section is placed between the inner peripheral surface of the head pipe and an outer peripheral surface of the steering stem.
