Abstract
A carrier for holding a wheel unit, which is easy and simple to handle (operate), and is capable of exactly switching a condition in which a rotation of a rear wheel is restricted, and a condition in which the rotation of the rear wheel is allowed is proposed. The carrier includes: a body; a sliding member capable of being slid in one direction and held on one of a first holding position and a second holding position; an urging member urging the sliding member along the one direction. The position on which the sliding member is held after the sliding member has been returned by an urging force of the urging member, is alternately changed between the first holding position and the second holding position.

A carrier for holding a wheel unit including a wheel and an axle rotatably holding the wheel, comprising:
- a body for holding the axle of the wheel unit;
- a sliding member capable of being slid in one direction with respect to the body, the sliding member being configured to be held on one of a first holding position and a second holding position which is located nearer to one side along the one direction than the first holding position;
- an urging member supported on the body, the urging member being configured to urge the sliding member to the body from the one side to the other side along the one direction;
- and
- a restriction engagement member attached to the sliding member, the restriction engagement member being configured to be engaged with the wheel unit so as to restrict a rotation of the wheel with respect to the axle, when the sliding member is held on one of the first holding position and the second holding position, and being configured to be disengaged from the wheel unit so as to allow the rotation of the wheel with respect to the axle, when the sliding member is held on the other of the first holding position and the second holding position;
- wherein the sliding member is configured such that the position on which the sliding member is held after the sliding member has been returned from the one side to the other side by an urging force of the urging member, is alternately changed between the first holding position and the second holding position, for each time when the sliding member is slid from the other side toward the one side along the one direction,
- wherein the axle is received in a hole formed in the body and in an elongated hole formed in the sliding member, the elongated hole being formed at a position, facing the hole of the body of the sliding member, and
- wherein one of the body and the sliding member includes a surface which is substantially in parallel with the one direction and has a linearly extending groove, an insertion member is supported on the other of the body and the sliding member and engages with the linearly extending groove, and the linearly extending groove includes a path with variable depth.

A stroller comprising:
- a frame structure including a front leg and a pair of rear legs;
- and
- a pair of rear wheel carriers attached to the respective rear legs;
- a pair of first rear wheel units each including an axle detachably supported on each rear wheel carrier and a first wheel rotatably held on the axle;
- and
- a pair of second rear wheel units each including an axle detachably supported on each rear wheel carrier, and a second wheel rotatably held on the axle, the pair of second rear wheel units being alternatively used in place of the first rear wheel units, a diameter of the first wheel and a diameter of the second wheel differ from each other,
- wherein each of the pair of rear wheel carriers includes:
- a body for holding the axle of the wheel unit;
- a sliding member capable of being slid in one direction with respect to the body, the sliding member being configured to be held on one of a first holding position and a second holding position which is located nearer to one side along the one direction than the first holding position;
- an urging member supported on the body, the urging member being configured to urge the sliding member to the body from the one side to the other side along the one direction;
- and
- a restriction engagement member attached to the sliding member, the restriction engagement member being configured to be engaged with the wheel unit so as to restrict a rotation of the wheel with respect to the axle, when the sliding member is held on one of the first holding position and the second holding position, and being configured to be disengaged from the wheel unit so as to allow the rotation of the wheel with respect to the axle, when the sliding member is held on the other of the first holding position and the second holding position,
- wherein the sliding member is configured such that the position on which the sliding member is held after the sliding member has been returned from the one side to the other side by an urging force of the urging member, is alternately changed between the first holding position and the second holding position, for each time when the sliding member is slid from the other side toward the one side along the one direction, and
- wherein the axle is received in a hole formed in the body of at least one of the pair of rear wheel carriers and in an elongated hole formed in the sliding member, the elongated hole formed at a position, facing the hole of the body, of the sliding member.
